(we write all the config so you don't have to), but Redwood's also built to help you make more accessible websites. +Accessibility shouldn't be a nice-to-have. +It should be a given from the start. +A core feature that's built-in and well-supported. + +There's a lot of great tooling out there that'll not only help you build accessible websites, but also help you learn exactly what that means. + +> **Does tooling obviate the need for manual testing?** +> +> No—even with all the tooling in the world, manual testing is still important, especially for accessibility. +> But just because tooling doesn't catch everything doesn't mean it's not valuable. +> It'd be much harder to learn what to look for without it. + +## Accessible Routing + +For single-page applications (SPAs), accessibility starts with the router. +Without a full-page refresh, you just can't be sure that things like announcements and focus are being taken care of the way they're supposed to be. +Here's a great example of [how disorienting SPAs can be to screen-reader users](https://www.youtube.com/watch?v=NKTdNv8JpuM). +On navigation, nothing's announced. +The lack of an announcement isn't just buggy behavior—it's broken. + +Normally, the onus would be on you as a developer to announce to screen-reader users that they've navigated somewhere new. +That's a lot to ask—and hard to get right—especially when you're just trying to build your app. + +Luckily, if you're writing thoughtful content and marking it up semantically, there's nothing you have to do! +The router automatically announces pages on navigation, and looks for announcements in this order: + +1. The `RouteAnnouncement` component +2. The page's `

` +3. `document.title` +4. `location.pathname` + +The reason for this order is that announcements should be as specific as possible. +more specific usually means more descriptive, and more descriptive usually means that users can not only orient themselves and navigate through the content, but also find it again. + +> If you're not sure if your content is descriptive enough, see the [W3 guidelines](https://www.w3.org/WAI/WCAG21/Techniques/general/G88.html). + +Even though Redwood looks for a `RouteAnnouncement` component first, you don't have to have one on every page—it's more than ok for the `

` to be what's announced. +`RouteAnnouncement` is there for when the situation calls for a custom announcement. + +### `RouteAnnouncement` + +The way `RouteAnnouncement` works is simple: its children will be announced. +Note that this can be something on the page or can be something that's visually hidden using the `visuallyHidden` prop: + +```jsx title="web/src/pages/HomePage/HomePage.js" +import { RouteAnnouncement } from '@redwoodjs/router' + +const HomePage = () => { + return ( + // This will still be visible + +

Welcome to my site!

+ + ) +} + +export default HomePage +``` + +```jsx title="web/src/pages/AboutPage/AboutPage.js" +import { RouteAnnouncement } from '@redwoodjs/router' + +const AboutPage = () => { + return ( +

Welcome to my site!

+ // This won't be visible + // highlight-start + + All about me + + // highlight-end + ) +} + +export default AboutPage +``` + +`visuallyHidden` shouldn't be the first thing you reach for—it's good to maintain parity between your site's visual and audible experiences. +But it's there if you need it. + +## Focus + +On page change, Redwood Router resets focus to the top of the DOM so that users can navigate through the new page. +While this is the expected behavior (and the behavior you usually want), for some pages—especially those with a lot of navigation—it can be cumbersome for users to have tab through navigation before getting to the main point. +(And that goes for every page change!) + +Right now, there's two ways to alleviate this: with skip links or the `RouteFocus` component. + +### Skip Links + +Since the main content isn't usually the first thing on the page, it's a best practice to provide a shortcut for keyboard and screen-reader users to skip to it. +Skip links do just that, and if you generate a layout using the `--skipLink` option, you'll get one with a skip link: + +``` +yarn rw g layout main --skipLink +``` + +```jsx title="web/src/layouts/MainLayout/MainLayout.js" +import { SkipNavLink, SkipNavContent } from '@redwoodjs/router' +import '@redwoodjs/router/skip-nav.css' + +const MainLayout = ({ children }) => { + return ( + <> + + + +
{children}
+ + ) +} + +export default MainLayout +``` + +`SkipNavLink` renders a link that remains hidden till focused and `SkipNavContent` renders a div as the target for the link. +The code for these components comes from Reach UI. For more details, see [Reach UI's docs](https://reach.tech/skip-nav/#reach-skip-nav). + +One thing you'll probably want to do is change the URL the skip link sends the user to when activated. +You can do that by changing the `contentId` and `id` props of `SkipNavLink` and `SkipNavContent` respectively: + +```jsx + +{/* ... */} + +``` + +If you'd prefer to implement your own skip link, [Ben Myers' blog](https://benmyers.dev/blog/skip-links/) is a great resource, and a great place to read about accessibility in general. + +### `RouteFocus` + +Sometimes you don't want to just skip the nav, but send a user somewhere. +In this situation, you of course have the foresight that that place is where the user wants to be. +So please use this at your discretion—sending a user to an unexpected location can be worse than sending them back the top. + +Having said that, if you know that on a particular page change a user's focus is better off being directed to a particular element, the `RouteFocus` component is what you want: + +```jsx title="web/src/pages/ContactPage/ContactPage.js" +// highlight-next-line +import { RouteFocus } from '@redwoodjs/router' + +const ContactPage = () => ( + + + // The contact form the user actually wants to interact with + // highlight-start + + + + // highlight-end +) + +export default ContactPage +``` + +`RouteFocus` tells the router to send focus to it's child on page change. In the example above, when the user navigates to the contact page, the name text field on the form is focused—the first field of the form they're here to fill out. + +

You should keep +// the shape of this object (i.e. keep all the key names) but change all the +// values/functions to use methods from the auth service provider client sdk +// you're integrating with +function createAuthImplementation(client: AuthClient) { + return { + type: 'custom-auth', + client, + login: async () => client.login(), + logout: async () => client.logout(), + signup: async () => client.signup(), + getToken: async () => client.getToken(), + /** + * Actual user metadata might look something like this + * { + * "id": "11111111-2222-3333-4444-5555555555555", + * "aud": "authenticated", + * "role": "authenticated", + * "roles": ["admin"], + * "email": "email@example.com", + * "app_metadata": { + * "provider": "email" + * }, + * "user_metadata": null, + * "created_at": "2016-05-15T19:53:12.368652374-07:00", + * "updated_at": "2016-05-15T19:53:12.368652374-07:00" + * } + */ + getUserMetadata: async () => client.getUserMetadata(), + } +} +``` + +This may seem like a lot, but it's actually not so bad: it's just about mapping the client's functions to these properties, many of which are pretty straightforward. +The fact that this is eventually the `useAuth` hook is hidden a bit—`createAuthImplementation` gets passed to `createAuthentication`, which returns the `AuthProvider` component and `useAuth` hook—but you don't have to concern yourself with that here. + +Again, let's take all the reading and trial and error you'll have to do for granted, though it may be long and tedious: + +```ts title="web/src/auth.ts" +function createAuthImplementation(client: AuthClient) { + return { + type: 'custom-auth', + client, + // See sign in options at https://docs.nhost.io/reference/javascript/auth/sign-in + login: async (options) => { + return await client.auth.signIn(options) + }, + // See sign out options at https://docs.nhost.io/reference/javascript/auth/sign-out + logout: async (options) => { + return await client.auth.signOut(options) + }, + // See sign up options at https://docs.nhost.io/reference/javascript/auth/sign-up + signup: async (options) => { + return await client.auth.signUp(options) + }, + getToken: async () => { + return (await client.auth.getJWTToken()) || null + }, + // See https://docs.nhost.io/reference/javascript/auth/get-user + getUserMetadata: async () => { + return await client.auth.getUser() + }, + restoreAuthState: async () => { + return await client.auth.refreshSession() + }, + } +} +``` + +That's it for the web side. +Let's head over to the api side. + +## api side + +Now that we've set up the web side, every GraphQL request includes a token. +But without a way to verify and decode that token, the api side doesn't know what to do with it, so let's start there. + +In `api/src/lib/auth.ts`, make an empty function, `authDecoder`. +Eventually we'll pass this to the `createGraphQLHandler` function in `api/src/graphql.ts`. +The GraphQL server calls it with two arguments, the token and the type. Both are strings: + +```ts title="api/src/lib/auth.ts" +export const authDecoder = async (token: string, type: string) => { + // decode token... +} +``` + +First, let's make sure that the type is the same as the type in `createAuthImplementation`, `'custom-auth'`. If it's not, we can call it quits: + +```ts title="api/src/lib/auth.ts" +export const authDecoder = async (token: string, type: string) => { + if (type !== 'custom-auth') { + return null + } + + // decode token... +} +``` + +Now let's verify and decode the token. +We'll use the npm module [jose](https://www.npmjs.com/package/jose) to do that; it has a `jwtVerify` function that does exactly what we want. +Go ahead and add it: + +``` +yarn workspace api add jose +``` + +For `jwtVerify` to do it's job, it needs the secret. +Time for another trip to your Nhost application's dashboard. +This time you're looking for "NHOST_JWT_SECRET". +Just like "NHOST_BACKEND_URL", it should be in "Settings", "Environment Variables". +(This one is a JSON object, with two properties, `type` and `key`. We just need `key`.) +Add that one to your project's `.env` file (no need to put it in `redwood.toml` though): + +```shell title=".env" +NHOST_JWT_SECRET="..." +``` + +Now we can use it in the `authDecoder`: + +```ts title="api/src/lib/auth.ts" +import { jwtVerify } from 'jose' + +export const authDecoder = async (token: string, type: string) => { + if (type !== 'custom-auth') { + return null + } + + const secret = new TextEncoder().encode(process.env.NHOST_JWT_SECRET) + + const decoded = await jwtVerify(token, secret) + + return decoded +} +``` + +Great—now we've got a way of decoding the token in requests coming from the web side. +Just one more important step that's easy to overlook: we have to pass this function to `createGraphQLHandler` in `api/src/functions/graphql.ts`: + +```ts title="api/src/functions/graphql.ts" +// highlight-next-line +import { authDecoder, getCurrentUser } from 'src/lib/auth' + +// ... + +export const handler = createGraphQLHandler({ + // highlight-next-line + authDecoder, + getCurrentUser, + // ... +}) +``` + +That should be enough; now, things should just work. +Let's make sure: if this is a brand new project, generate a home page. +There we'll try to sign up by destructuring `signUp` from the `useAuth` hook (import that from `'src/auth'`). We'll also destructure and display `isAuthenticated` to see if it worked: + +```tsx title="web/src/pages/HomePage.tsx" +import { useAuth } from 'src/auth' + +const HomePage = () => { + const { isAuthenticated, signUp } = useAuth() + + return ( + <> + {/* MetaTags, h1, paragraphs, etc. */} + +

{JSON.stringify({ isAuthenticated })}

+ + + ) +} +``` + +Nhost doesn't redirect to a hosted sign-up page or open a sign-up modal. +In a real app, you'd build a form here, but we're going to hardcode an email and password. +One thing you may want to do before signing up: disable email verification, else you'll actually have to verify your email. +Go to back to "Settings" in your Nhost application, but this time click "Sign in methods". +There should be a checkbox there, "Require Verified Emails". +Toggle it off. +Now try signing up and you should see `{"isAuthenticated":true}` on the page. diff --git a/docs/versioned_docs/version-8.2/auth/dbauth.md b/docs/versioned_docs/version-8.2/auth/dbauth.md new file mode 100644 index 000000000000..b4207909941c --- /dev/null +++ b/docs/versioned_docs/version-8.2/auth/dbauth.md @@ -0,0 +1,709 @@ +--- +sidebar_label: Self-hosted (dbAuth) +--- + +# Self-hosted Authentication (dbAuth) + +Redwood's own **dbAuth** provides several benefits: + +- Use your own database for storing user credentials +- Use your own login, signup and forgot password pages (or use Redwood's pre-built ones) +- Customize login session length +- No external dependencies +- No user data ever leaves your servers +- No additional charges/limits based on number of users +- No third party service outages affecting your site + +And potentially one large drawback: + +- Use your own database for storing user credentials + +However, we're following best practices for storing these credentials: + +1.

On an attempted login, a serverless function on the api-side checks whether a user exists with the given username (internally, dbAuth refers to this field as _username_ but you can use anything you want, like an email address). If a user with that username is found, does their salted and hashed password match the one in the database? + +If so, an [HttpOnly](https://owasp.org/www-community/HttpOnly), [Secure](https://owasp.org/www-community/controls/SecureCookieAttribute), [SameSite](https://owasp.org/www-community/SameSite) cookie (dbAuth calls this the "session cookie") is sent back to the browser containing the ID of the user. The content of the cookie is a simple string, but AES encrypted with a secret key (more on that later). + +When the user makes a GraphQL call, we decrypt the cookie and make sure that the user ID contained within still exists in the database. If so, the request is allowed to proceed. + +If there are any shenanigans detected (the cookie can't be decrypted properly, or the user ID found in the cookie does not exist in the database) the user is immediately logged out by expiring the session cookie. + +## Setup + +A single CLI command will get you everything you need to get dbAuth working, minus the actual login/signup pages: + +```bash +yarn rw setup auth dbAuth +``` + +You will be prompted to ask if you want to enable **WebAuthn** support.

[Read more about WebAuthn usage and config below](#webauthn). + +Read the post-install instructions carefully as they contain instructions for adding database fields for the hashed password and salt, as well as how to configure the auth serverless function based on the name of the table that stores your user data.

The comments above each key will explain what goes where. Here's an overview of the more important options: + +### allowedUserFields + +```javascript +allowedUserFields: ['id', 'email'] +``` + +Most of the auth handlers accept a `user` argument that you can reference in the body of the function. These handlers also sometimes return that `user` object. As a security measure, `allowedUserFields` defines the only properties that will be available in that object so that sensitive data isn't accidentally leaked by these handlers to the client. + +:::info + +The `signup` and `forgotPassword` handlers return to the client whatever data is returned from their handlers, which can be used to display something like the email address that a verification email was just sent to. Without `allowedUserFields` it would be very easy to include the user's `hashedPassword` and `salt` in that response (just return `user` from those handlers) and then any customer could open the Web Inspector in their browser and see those values in plain text! + +::: + +`allowedUserFields` is defaulted to `id` and `email` but you can add any property on `user` to that list. + +### login.enabled + +Allow users to call login. Defaults to true. Needs to be explicitly set to false to disable the flow. + +```javascript +login: { + enabled: false +} +``` + +### login.handler() + +If you want to do something other than immediately let a user log in if their username/password is correct, you can add additional logic in `login.handler()`. For example, if a user's credentials are correct, but they haven't verified their email address yet, you can throw an error in this function with the appropriate message and then display it to the user. If the login should proceed, simply return the user that was passed as the only argument to the function: + +```javascript +login: { + handler: (user) => { + if (!user.verified) { + throw new Error('Please validate your email first!') + } else { + return user + } + } +} +``` + +### signup.enabled + +Allow users to sign up. Defaults to true. Needs to be explicitly set to false to disable the flow. + +```javascript +signup: { + enabled: false +} +``` + +### signup.handler() + +This function should contain the code needed to actually create a user in your database. You will receive a single argument which is an object with all of the fields necessary to create the user (`username`, `hashedPassword` and `salt`) as well as any additional fields you included in your signup form in an object called `userAttributes`: + +```javascript +signup: { + handler: ({ username, hashedPassword, salt, userAttributes }) => { + return db.user.create({ + data: { + email: username, + hashedPassword: hashedPassword, + salt: salt, + name: userAttributes.name, + }, + }) + } +} +``` + +Before `signup.handler()` is invoked, dbAuth will check that the username is unique in the database and throw an error if not. + +There are three things you can do within this function depending on how you want the signup to proceed: + +1. If everything is good and the user should be logged in after signup: return the user you just created +2. If the user is safe to create, but you do not want to log them in automatically: return a string, which will be returned by the `signUp()` function you called after destructuring it from `useAuth()` (see code snippet below) +3. If the user should _not_ be able to sign up for whatever reason: throw an error in this function with the message to be displayed + +You can deal with case #2 by doing something like the following in a signup component/page: + +```jsx +const { signUp } = useAuth() + +const onSubmit = async (data) => { + const response = await signUp({ ...data }) + + if (response.message) { + toast.error(response.message) // user created, but not logged in + } else { + toast.success('Welcome!') // user created and logged in + navigate(routes.dashboard()) + } +} +``` + +### signup.passwordValidation() + +This function is used to validate that the password supplied at signup meets certain criteria (length, randomness, etc.). By default it just returns `true` which means the password is always considered valid, even if only a single character (dbAuth features built-in validation that the password is not blank, an empty string, or made up of only spaces). Modify it to enforce whatever methodology you want on the password. + +If the password is valid, return `true`. Otherwise, throw the `PasswordValidationError` along with a (optional) message explaining why: + +```javascript +signup: { + passwordValidation: (password) => { + if (password.length < 8) { + throw new PasswordValidationError( + 'Password must be at least 8 characters' + ) + } + + if (!password.match(/[A-Z]/)) { + throw new PasswordValidationError( + 'Password must contain at least one capital letter' + ) + } + + return true + } +} +``` + +For the best user experience you should include the same checks on the client side and avoid the roundtrip to the server altogether if the password is invalid. However, having the checks here makes sure that someone can't submit a user signup programmatically and skirt your password requirements. + +### forgotPassword.enabled + +Allow users to request a new password via a call to `forgotPassword`. Defaults to true. Needs to be explicitly set to false to disable the flow. +When disabling this flow you probably want to disable `resetPassword` as well. + +```javascript +forgotPassword: { + enabled: false +} +``` + +### forgotPassword.handler() + +This handler is invoked if a user is found with the username/email that they submitted on the Forgot Password page, and that user will be passed as an argument. Inside this function is where you'll send the user a link to reset their password—via an email is most common. The link will, by default, look like: + +``` +https://example.com/reset-password?resetToken=${user.resetToken} +``` + +If you changed the path to the Reset Password page in your routes you'll need to change it here. If you used another name for the `resetToken` database field, you'll need to change that here as well: + +``` +https://example.com/reset-password?resetKey=${user.resetKey} +``` + +> Note that although the user table contains a hash of `resetToken`, only for the handler, `user.resetToken` will contain the raw `resetToken` to use for generating a password reset link. + +### resetPassword.enabled + +Allow users to reset their password via a code from a call to `forgotPassword`. Defaults to true. Needs to be explicitly set to false to disable the flow. +When disabling this flow you probably want to disable `forgotPassword` as well. + +```javascript +resetPassword: { + enabled: false +} +``` + +### resetPassword.handler() + +This handler is invoked after the password has been successfully changed in the database. Returning something truthy (like `return user`) will automatically log the user in after their password is changed. If you'd like to return them to the login page and make them log in manually, `return false` and redirect the user in the Reset Password page. + +### usernameMatch + +This configuration allows you to perform a case insensitive check on a username at the point of db check. You will need to provide the configuration of your choice for both signup and login. + +```javascript +signup: { + usernameMatch: 'insensitive' +} +``` + +```javascript +login: { + usernameMatch: 'insensitive' +} +``` + +By default no setting is required. This is because each db has its own rules for enabling this feature. To enable please see the table below and pick the correct 'userMatchString' for your db of choice. + +| DB | Default | usernameMatchString | notes | +| -------------------- | ------------------ | ------------------- | ---------------------------------------------------------------------------- | +| Postgres | 'default' | 'insensitive' | | +| MySQL | 'case-insensitive' | N/A | turned on by default so no setting required | +| MongoDB | 'default' | 'insensitive' | +| SQLite | N/A | N/A | [Not Supported] Insensitive checks can only be defined at a per column level | +| Microsoft SQL Server | 'case-insensitive' | N/A | turned on by default so no setting required | + +### Cookie config + +These options determine how the cookie that tracks whether the client is authorized is stored in the browser. The default configuration should work for most use cases. If you serve your web and api sides from different domains you'll need to make some changes: set `SameSite` to `None` and then add [CORS configuration](#cors-config). + +```javascript +cookie: { + HttpOnly: true, + Path: '/', + SameSite: 'Strict', + Secure: true, + // Domain: 'example.com', +} +``` + +### CORS config + +If you're using dbAuth and your api and web sides are deployed to different domains then you'll need to configure CORS for both GraphQL in general and dbAuth. You'll also need to enable a couple of options to be sure and send/accept credentials in XHR requests. For more info, see the complete [CORS doc](cors.md#cors-and-authentication). + +### Error Messages + +There are several error messages that can be displayed, including: + +- Username/email not found +- Incorrect password +- Expired reset password token + +We've got some default error messages that sound nice, but may not fit the tone of your site. You can customize these error messages in `api/src/functions/auth.js` in the `errors` prop of each of the `login`, `signup`, `forgotPassword` and `resetPassword` config objects.

If your site is spread across multiple domains (for example, your site is at `example.com` but your api-side is deployed to `api.example.com`) you'll need to explicitly set a Domain so that the cookie is accessible to both. + +To do this, set the `cookie.Domain` property in your `api/src/functions/auth.js` configuration, set to the root domain of your site, which will allow it to be read by all subdomains as well. For example: + +```json title="api/src/functions/auth.js" +cookie: { + HttpOnly: true, + Path: '/', + SameSite: 'Strict', + Secure: process.env.NODE_ENV !== 'development' ? true : false, + Domain: 'example.com' +} +``` + +### Session Secret Key + +If you need to change the secret key that's used to encrypt the session cookie, or deploy to a new target (each deploy environment should have its own unique secret key) we've got a CLI tool for creating a new one: + +``` +yarn rw g secret +``` + +Note that the secret that's output is _not_ appended to your `.env` file or anything else, it's merely output to the screen.

There is another file, `.env.defaults`, which is meant to be safe to commit and contain simple ENV vars that your dev team can share. The encryption key for the session cookie is NOT one of these shareable vars! + +::: + +## WebAuthn + +[WebAuthn](https://webauthn.guide/) is a specification written by the W3C and FIDO with participation from Google, Mozilla, Microsoft, and others. It defines a standard way to use public key cryptography instead of a password to authenticate users. + +That's a very technical way of saying: users can log in with [TouchID](https://en.wikipedia.org/wiki/Touch_ID), [FaceID](https://en.wikipedia.org/wiki/Face_ID), [Windows Hello](https://support.microsoft.com/en-us/windows/learn-about-windows-hello-and-set-it-up-dae28983-8242-bb2a-d3d1-87c9d265a5f0), [Yubikey](https://www.yubico.com/), and more. + +image + +We'll refer to whatever biometric device that's used as simply a "device" below. The WebAuthn flow includes two "phases": + +1. **Registration**: the first time a new device is added for a user (a user can have multiple devices registered) +2. **Authentication**: the device is recognized and can be used to login on subsequent visits + +### User Experience + +The `LoginPage` generated by Redwood includes two new prompts on the login page, depending on the state of the user and whether they have registered their device yet or not: + +**Registration** + +The user is prompted to login with username/password: + +image + +Then asked if they want to enable WebAuthn: + +image + +If so, they are shown the browser's prompt to scan: + +image + +If they skip, they just proceed into the site as usual. If they log out and back in, they will be prompted to enable WebAuthn again. + +**Authentication** + +When a device is already registered then it can be used to skip username/password login. The user is immediately shown the prompt to scan when they land on the login page (if the prompt doesn't show, or they mistakenly cancel it, they can click "Open Authenticator" to show the prompt again) + +image + +They can also choose to go to use username/password credentials instead of their registered device. + +### How it Works + +The back and forth between the web and api sides works like this: + +**Registration** + +1. If the user selects to enable their device, a request is made to the server for "registration options" which is a JSON object containing details about the server and user (domain, username). +2. Your app receives that data and then makes a browser API call that says to start the biometric reader with the received options +3. The user scans their fingerprint/face and the browser API returns an ID representing this device, a public key and a few other fields for validation on the server +4. The ID, public key, and additional details are sent to the server to be verified. Assuming the are, the device is saved to the database in a `UserCredential` table (you can change the name if you want). The server responds by placing a cookie on the user's browser with the device ID (a random string of letters and numbers) + +A similar process takes place when authenticating: + +**Authentication** + +1. If the cookie from the previous process is present, the web side knows that the user has a registered device so a request is made to the server to get "authentication options" +2. The server looks up user who's credential ID is in the cookie and gets a list of all of the devices they have registered in the past. This is included along with the domain and username +3. The web side receives the options from the server and a browser API call is made. The browser first checks to see if the list of devices from the server includes the current device. If so, it prompts the user to scan their fingerprint/face (if the device is not in the list, the user will directed back to username/password signup) +4. The ID, public key, user details and a signature are sent to the server and checked to make sure the signature contains the expected data encrypted with the public key. If so, the regular login cookie is set (the same as if the user had used username/password login) + +In both cases, actual scanning and matching of devices is handled by the operating system: all we care about is that we are given a credential ID and a public key back from the device. + +### Browser Support + +WebAuthn is supported in the following browsers (as of July 2022): + +| OS | Browser | Authenticator | +| ------- | ------- | -------------------------------------------------------------- | +| macOS | Firefox | Yubikey Security Key NFC (USB), Yubikey 5Ci, SoloKey | +| macOS | Chrome | Touch ID, Yubikey Security Key NFC (USB), Yubikey 5Ci, SoloKey | +| iOS | All | Face ID, Touch ID, Yubikey Security Key NFC (NFC), Yubikey 5Ci | +| Android | Chrome | Fingerprint Scanner, caBLE | +| Android | Firefox | Screen PIN | + +### Configuration + +WebAuthn support requires a few updates to your codebase: + +1. Adding a `UserCredential` model +2. Adding configuration options in `api/src/functions/auth.js` +3. Adding a `client` to the `` in `App.js` +4. Adding an interface during the login process that prompts the user to enable their device + +:::info +If you setup dbAuth and generated the LoginPage with WebAuthn support then all of these steps have already been done for you! As described in the post-setup instructions you just need to add the required fields to your `User` model, create a `UserCredential` model, and you're ready to go! + +If you didn't setup WebAuthn at first, but decided you now want WebAuthn, you could run the setup and generator commands again with the `--force` flag to overwrite your existing files. Any changes you made will be overwritten, but if you do a quick diff in git you should be able to port over most of your changes. +::: + +### Schema Updates + +You'll need to add two fields to your `User` model, and a new `UserCredential` model to store the devices that are used and associate them with a user: + +```javascript title="api/db/schema.prisma" +datasource db { + provider = "sqlite" + url = env("DATABASE_URL") +} + +generator client { + provider = "prisma-client-js" + binaryTargets = "native" +} + +model User { + id Int @id @default(autoincrement()) + email String @unique + hashedPassword String + salt String + resetToken String? + resetTokenExpiresAt DateTime? + // highlight-start + webAuthnChallenge String? @unique + credentials UserCredential[] + // highlight-end +} + +// highlight-start +model UserCredential { + id String @id + userId Int + user User @relation(fields: [userId], references: [id]) + publicKey Bytes + transports String? + counter BigInt +} +// highlight-end +``` + +Run `yarn rw prisma migrate dev` to apply the changes to your database. + +:::warning Do Not Allow GraphQL Access to `UserCredential` + +As you can probably tell by the name, this new model contains secret credential info for the user. You **should not** make this data publicly available by adding an SDL file to `api/src/graphql`. + +Also: if you (re)generate the SDL for your `User` model, the generator will happily include the `credentials` relationship, assuming you want to allow access to that data (it does this automatically for all relaionships). This will result in an error and warning message in the console from the API server when it tries to read the new SDL file: the `User` SDL refers to a `UserCredential` type, which does not exist (there's no `userCredential.sdl.js` file to define it). + +If you see this notice after (re)generating, simply remove the following line from the `User` SDL: + +``` +credentials: [UserCredential]! +``` + +::: + +### Function Config + +Next we need to let dbAuth know about the new field and model names, as well as how you want WebAuthn to behave (see the highlighted section) + +```javascript title="api/src/functions/auth.js" +import { db } from 'src/lib/db' +import { DbAuthHandler } from '@redwoodjs/api' + +export const handler = async (event, context) => { + // assorted handler config here... + + const authHandler = new DbAuthHandler(event, context, { + db: db, + authModelAccessor: 'user', + // highlight-start + credentialModelAccessor: 'userCredential', + // highlight-end + authFields: { + id: 'id', + username: 'email', + hashedPassword: 'hashedPassword', + salt: 'salt', + resetToken: 'resetToken', + resetTokenExpiresAt: 'resetTokenExpiresAt', + // highlight-start + challenge: 'webAuthnChallenge', + // highlight-end + }, + + cookie: { + HttpOnly: true, + Path: '/', + SameSite: 'Strict', + Secure: process.env.NODE_ENV !== 'development' ? true : false, + }, + + forgotPassword: forgotPasswordOptions, + login: loginOptions, + resetPassword: resetPasswordOptions, + signup: signupOptions, + + // highlight-start + webAuthn: { + enabled: true, + expires: 60 * 60 * 14, + name: 'Webauthn Test', + domain: + process.env.NODE_ENV === 'development' ? 'localhost' : 'server.com', + origin: + process.env.NODE_ENV === 'development' + ? 'http://localhost:8910' + : 'https://server.com', + type: 'platform', + timeout: 60000, + credentialFields: { + id: 'id', + userId: 'userId', + publicKey: 'publicKey', + transports: 'transports', + counter: 'counter', + }, + }, + // highlight-end + }) + + return await authHandler.invoke() +} +``` + +- `credentialModelAccessor` specifies the name of the accessor that you call to access the model you created to store credentials. If your model name is `UserCredential` then this field would be `userCredential` as that's how Prisma's naming conventions work. +- `authFields.challenge` specifies the name of the field in the user model that will hold the WebAuthn challenge string. This string is generated automatically whenever a WebAuthn registration or authentication request starts and is one more verification that the browser request came from this user. A user can only have one WebAuthn request/response cycle going at a time, meaning that they can't open a desktop browser, get the TouchID prompt, then switch to iOS Safari to use FaceID, then return to the desktop to scan their fingerprint. The most recent WebAuthn request will clobber any previous one that's in progress. +- `webAuthn.enabled` is a boolean, denoting whether the server should respond to webAuthn requests. If you decide to stop using WebAuthn, you'll want to turn it off here as well as update the LoginPage to stop prompting. +- `webAuthn.expires` is the number of seconds that a user will be allowed to keep using their fingerprint/face scan to re-authenticate into your site. Once this value expires, the user _must_ use their username/password to authenticate the next time, and then WebAuthn will be re-enabled (again, for this length of time). For security, you may want to log users out of your app after an hour of inactivity, but allow them to easily use their fingerprint/face to re-authenticate for the next two weeks (this is similar to login on macOS where your TouchID session expires after a couple of days of inactivity). In this example you would set `login.expires` to `60 * 60` and `webAuthn.expires` to `60 * 60 * 24 * 14`. +- `webAuthn.name` is the name of the app that will show in some browser's prompts to use the device +- `webAuthn.domain` is the name of domain making the request. This is just the domain part of the URL, ex: `app.server.com`, or in development mode `localhost` +- `webAuthn.origin` is the domain _including_ the protocol and port that the request is coming from, ex: [https://app.server.com](https://app.server.com) In development mode, this would be `http://localhost:8910` +- `webAuthn.type`: the type of device that's allowed to be used (see [next section below](#webauthn-type-option)) +- `webAuthn.timeout`: how long to wait for a device to be used in milliseconds (defaults to 60 seconds) +- `webAuthn.credentialFields`: lists the expected field names that dbAuth uses internally mapped to what they're actually called in your model. This includes 5 fields total: `id`, `userId`, `publicKey`, `transports`, `counter`. + +### WebAuthn `type` Option + +The config option `webAuthn.type` can be set to `any`, `platform` or `cross-platform`: + +- `platform` means to _only_ allow embedded devices (TouchID, FaceID, Windows Hello) to be used +- `cross-platform` means to _only_ allow third party devices (like a Yubikey USB fingerprint reader) +- `any` means to allow both platform and cross-platform devices + +In some browsers this can lead to a pretty drastic UX difference. For example, here is the interface in Chrome on macOS with the included TouchID sensor on a Macbook Pro: + +#### **any** + +image + +If you pick "Add a new Android Phone" you're presented with a QR code: + +image + +If you pick "USB Security Key" you're given the chance to scan your fingerprint in a 3rd party USB device: + +image + +And finally if you pick "This device" you're presented with the standard interface you'd get if used `platform` as your type: + +image + +You'll have to decide if this UX tradeoff is worth it for your customers, as it can be pretty confusing when first presented with all of these options when someone is just used to using TouchID or FaceID. + +#### **platform** + +The `platform` option provides the simplest UI and one that users with a TouchID or FaceID will be immediately familiar with: + +image + +Note that you can also fallback to use your user account password (on the computer itself) in addition to TouchID: + +image + +Both the password and TouchID scan will count as the same device, so users can alternate between them if they want. + +#### **cross-platform** + +This interface is the same as `any`, but without the option to pick "This device": + + + +So while the `any` option is the most flexible, it's also the most confusing to users. If you do plan on allowing any device, you may want to do a user-agent check and try to explain to users what the different options actually mean. + +The api-side is now ready to go. + +### App.js Updates + +If you generated your login/signup pages with `yarn rw g dbAuth --webauthn` then all of these changes are in place and you can start using WebAuthn right away! Otherwise, read on. + +First you'll need to import the `WebAuthnClient` and give it to the `` component: + +```jsx title="web/src/App.js" +import { AuthProvider } from '@redwoodjs/auth' +// highlight-start +import WebAuthnClient from '@redwoodjs/auth-dbauth-web/webAuthn' +// highlight-end +import { FatalErrorBoundary, RedwoodProvider } from '@redwoodjs/web' +import { RedwoodApolloProvider } from '@redwoodjs/web/apollo' + +import FatalErrorPage from 'src/pages/FatalErrorPage' +import Routes from 'src/Routes' + +import './scaffold.css' +import './index.css' + +const App = () => ( + + + // highlight-start + + // highlight-end + + + + + + +) + +export default App +``` + +Now you're ready to access the functionality added by the WebAuthn client. The easiest way to do this would be to generate a new `LoginPage` with `yarn rw g dbAuth --webauthn`, even if it's in a brand new, throwaway app, and copy the pieces you need (or just replace your existing login page with it). + +The gist of building a login flow is that you now need to stop after username/password authentication and, if the browser supports WebAuthn, give the user the chance to register their device. If they come to the login page and already have the `webAuthn` cookie then you can show the prompt to authenticate, skipping the username/password form completely. This is all handled in the LoginPage template that Redwood generates for you. + +### WebAuthn Client API + +The `client` that we gave to the `AuthProvider` can be destructured from `useAuth()`: + +```javascript +const { isAuthenticated, client, logIn } = useAuth() +``` + +`client` gives you access to four functions for working with WebAuthn: + +- `client.isSupported()`: returns a Promise which resolves to a boolean—whether or not WebAuthn is supported in the current browser browser +- `client.isEnabled()`: returns a boolean for whether the user currently has a `webAuthn` cookie, which means this device has been registered already and can be used for login +- `client.register()`: returns a Promise which gets options from the server, presents the prompt to scan your fingerprint/face, and then sends the result up to the server. It will either resolve successfully with an object `{ verified: true }` or throw an error. This function is used when the user has not registered this device yet (`client.isEnabled()` returns `false`). +- `client.authenticate()`: returns a Promise which gets options from the server, presents the prompt to scan the user's fingerprint/face, and then sends the result up to the server. It will either resolve successfully with an object `{ verified: true }` or throw an error. This should be used when the user has already registered this device (`client.isEnabled()` returns `true`) diff --git a/docs/versioned_docs/version-8.2/auth/firebase.md b/docs/versioned_docs/version-8.2/auth/firebase.md new file mode 100644 index 000000000000..6fa20136e3e4 --- /dev/null +++ b/docs/versioned_docs/version-8.2/auth/firebase.md @@ -0,0 +1,79 @@ +--- +sidebar_label: Firebase +--- + +# Firebase Authentication + +To get started, run the setup command: + +```bash +yarn rw setup auth firebase +``` + +This installs all the packages, writes all the files, and makes all the code modifications you need. +For a detailed explanation of all the api- and web-side changes that aren't exclusive to Firebase, see the top-level [Authentication](../authentication.md) doc. +For now, let's focus on Firebase's side of things. + +If you don't have a Firebase account yet, now's the time to make one: navigate to https://firebase.google.com and click "Go to console", sign up, and create a project. +After it's ready, we'll get the API keys. + +To get the API keys, we need to add a web app to our project. +Click the `` icon in main call to action on the dashboard—"Get started by adding Firebase to your app". +Give your app a nickname, then you should see the API keys. +Since we're only using Firebase for auth, we only need `apiKey`, `authDomain`, and `projectId`. +Copy them into your project's `.env` file: + +```bash title=".env" +FIREBASE_API_KEY="..." +FIREBASE_AUTH_DOMAIN="..." +FIREBASE_PROJECT_ID="..." +``` + +Lastly, include `FIREBASE_API_KEY` and `FIREBASE_AUTH_DOMAIN` in the list of env vars that should be available to the web side (`FIREBASE_PROJECT_ID` is for the api side): + +```toml title="redwood.toml" +[web] + # ... + includeEnvironmentVariables = ["FIREBASE_API_KEY", "FIREBASE_AUTH_DOMAIN"] +``` + +We've hooked up our Firebase app to our Redwood app, but if you try it now, it won't work. +That's because we haven't actually enabled auth in our Firebase app yet. + +Back to the dashboard one more time: in the nav on the left, click "Build", "Authentication", and "Get started". +We're going to go with "Email/Password" here, but feel free to configure things as you wish. +Click "Email/Password", enable it, and click "Save". + +That should be enough; now, things should just work. +Let's make sure: if this is a brand new project, generate a home page. +There we'll try to sign up by destructuring `signUp` from the `useAuth` hook (import that from `'src/auth'`).

All of the logic around sending the email is packaged up as a **job** and a **job worker** is responsible for executing it. + +Each job is completely self-contained and has everything it needs to perform its own task. + +### Overview + +There are three components to the Background Job system in Redwood: + +1. Scheduling +2. Storage +3. Execution + +**Scheduling** is the main interface to background jobs from within your application code. This is where you tell the system to run a job at some point in the future, whether that's: + +- as soon as possible +- delay for an amount of time before running +- run at a specific datetime in the future + +**Storage** is necessary so that your jobs are decoupled from your running application. The job system interfaces with storage via an **adapter**. With the included `PrismaAdapter`, jobs are stored in your database. This allows you to scale everything independently: the api server (which is scheduling jobs), the database (which is storing the jobs ready to be run), and the job workers (which are executing the jobs). + +**Execution** is handled by a **job worker**, which takes a job from storage, executes it, and then does something with the result, whether it was a success or failure. + +:::info Job execution time is never guaranteed + +When scheduling a job, you're really saying "this is the earliest possible time I want this job to run": based on what other jobs are in the queue, and how busy the workers are, they may not get a chance to execute this one particular job for an indeterminate amount of time. + +The only thing that's guaranteed is that a job won't run any _earlier_ than the time you specify. + +::: + +### Queues + +Jobs are organized by a named **queue**. This is simply a string and has no special significance, other than letting you group jobs. Why group them? So that you can potentially have workers with different configurations working on them. Let's say you send a lot of emails, and you find that among all your other jobs, emails are starting to be noticeably delayed when sending. You can start assigning those jobs to the "email" queue and create a new worker group that _only_ focuses on jobs in that queue so that they're sent in a more timely manner. + +Jobs are sorted by **priority** before being selected to be worked on. Lower numbers mean higher priority: + +![job-queues](/img/background-jobs/jobs-queues.png) + +You can also increase the number of workers in a group. If we bumped the group working on the "default" queue to 2 and started our new "email" group with 1 worker, once those workers started we would see them working on the following jobs: + +![job-workers](/img/background-jobs/jobs-workers.png) + +## Quick Start + +Start here if you want to get up and running with jobs as quickly as possible and worry about the details later. + +### Setup + +Run the setup command to get the jobs configuration file created and migrate the database with a new `BackgroundJob` table: + +```bash +yarn rw setup jobs +yarn rw prisma migrate dev +``` + +This created `api/src/lib/jobs.js` (or `.ts`) with a sensible default config. You can leave this as is for now. + +### Create a Job + +```bash +yarn rw g job SampleJob +``` + +This created `api/src/jobs/SampleJob/SampleJob.js` and a test and scenario file. For now the job just outputs a message to the logs, but you'll fill out the `perform()` function to take any arguments you want and perform any work you want to do. Let's update the job to take a user's `id` and then just print that to the logs: + +```js +import { jobs } from 'src/lib/jobs' + +export const SampleJob = jobs.createJob({ + queue: 'default', + // highlight-start + perform: async (userId) => { + jobs.logger.info(`Received user id ${userId}`) + }, + // highlight-end +}) +``` + +### Schedule a Job + +You'll most likely be scheduling work as the result of one of your service functions being executed. Let's say we want to schedule our `SampleJob` whenever a new user is created: + +```js title="api/src/services/users/users.js" +import { db } from 'src/lib/db' +// highlight-start +import { later } from 'src/lib/jobs' +import { SampleJob } from 'src/jobs/SampleJob' +// highlight-end + +export const createUser = async ({ input }) => { + const user = await db.user.create({ data: input }) + // highlight-next-line + await later(SampleJob, [user.id], { wait: 60 }) + return user +} +``` + +The first argument is the job itself, the second argument is an array of all the arguments your job should receive. The job itself defines them as normal, named arguments (like `userId`), but when you schedule you wrap them in an array (like `[user.id]`). The third argument is an optional object that provides a couple of options. In this case, the number of seconds to `wait` before this job will be run (60 seconds). + +### Executing a Job + +Start the worker process to find jobs in the DB and execute them: + +```bash +yarn rw jobs work +``` + +This process will stay attached to the terminal and show you debug log output as it looks for jobs to run. Note that since we scheduled our job to wait 60 seconds before running, the runner will not find a job to work on right away (unless it's already been a minute since you scheduled it!). + +That's the basics of jobs! Keep reading to get a more detailed walkthrough, followed by the API docs listing all the various options. We'll wrap up with a discussion of using jobs in a production environment. + +## In-Depth Start + +Let's go into more depth in each of the parts of the job system. + +### Installation + +To get started with jobs, run the setup command: + +```bash +yarn rw setup jobs +``` + +This will add a new model to your Prisma schema, and create a configuration file at `api/src/lib/jobs.js` (or `.ts` for a TypeScript project). You'll need to run migrations in order to actually create the model in your database: + +```bash +yarn rw prisma migrate dev +``` + +This added the following model: + +```prisma +model BackgroundJob { + id Int @id @default(autoincrement()) + attempts Int @default(0) + handler String + queue String + priority Int + runAt DateTime? + lockedAt DateTime? + lockedBy String? + lastError String? + failedAt DateTime? + createdAt DateTime @default(now()) + updatedAt DateTime @updatedAt +} +``` + +Let's look at the config file that was generated. Comments have been removed for brevity: + +```js +import { PrismaAdapter, JobManager } from '@redwoodjs/jobs' + +import { db } from 'src/lib/db' +import { logger } from 'src/lib/logger' + +export const jobs = new JobManager({ + adapters: { + prisma: new PrismaAdapter({ db, logger }), + }, + queues: ['default'], + logger, + workers: [ + { + adapter: 'prisma', + logger, + queue: '*', + count: 1, + maxAttempts: 24, + maxRuntime: 14_400, + deleteFailedJobs: false, + sleepDelay: 5, + }, + ], +}) + +export const later = jobs.createScheduler({ + adapter: 'prisma', +}) +``` + +Two variables are exported: one is an instance of the `JobManager` called `jobs` on which you'll call functions to create jobs and schedulers. The other is `later` which is an instance of the `Scheduler`, which is responsible for getting your job into the storage system (out of the box this will be the database thanks to the `PrismaAdapter`). + +We'll go into more detail on this file later (see [JobManager Config](#jobmanager-config)), but what's there now is fine to get started creating a job. + +### Creating New Jobs + +We have a generator that creates a job in `api/src/jobs`: + +```bash +yarn rw g job SendWelcomeEmail +``` + +Jobs are defined as a plain object and given to the `createJob()` function (which is called on the `jobs` export in the config file above). An example `SendWelcomeEmailJob` may look something like: + +```js +import { db } from 'src/lib/db' +import { mailer } from 'src/lib/mailer' +import { jobs } from 'src/lib/jobs' + +export const SendWelcomeEmailJob = jobs.createJob({ + queue: 'default', + perform: async (userId) => { + const user = await db.user.findUnique({ where: { id: userId } }) + await mailer.send(WelcomeEmail({ user }), { + to: user.email, + subject: `Welcome to the site!`, + }) + }, +}) +``` + +At a minimum, a job must contain the name of the `queue` the job should be saved to, and a function named `perform()` which contains the logic for your job. You can add additional properties to the object to support the task your job is performing, but `perform()` is what's invoked by the job worker that we'll see later. + +Note that `perform()` can take any argument(s) you want (or none at all), but it's a best practice to keep them as simple as possible. With the `PrismaAdapter` the arguments are stored in the database, so the list of arguments must be serializable to and from a string of JSON. + +:::info Keeping Arguments Simple + +Most jobs will probably act against data in your database, so it makes sense to have the arguments simply be the `id` of those database records. When the job executes it will look up the full database record and then proceed from there. + +If it's likely that the data in the database will change before your job is actually run, but you need the job to run with the original data, you may want to include the original values as arguments to your job. This way the job is sure to be working with those original values and not the potentially changed ones in the database. + +::: + +### Scheduling Jobs + +Remember the `later` export in the jobs config file: + +```js +export const later = jobs.createScheduler({ + adapter: 'prisma', +}) +``` + +You call this function, passing the job, job arguments, and an optional options object when you want to schedule a job. Let's see how we'd schedule our welcome email to go out when a new user is created: + +```js +// highlight-start +import { later } from 'src/lib/jobs' +import { SendWelcomeEmailJob } from 'src/jobs/SendWelcomeEmailJob' +// highlight-end + +export const createUser = async ({ input }) { + const user = await db.user.create({ data: input }) + // highlight-next-line + await later(SendWelcomeEmailJob, [user.id]) + return user +} +``` + +By default the job will run as soon as possible. If you wanted to wait five minutes before sending the email you can set a `wait` time to a number of seconds: + +```js +later(SendWelcomeEmailJob, [user.id], { wait: 300 }) +``` + +Or run it at a specific datetime: + +```js +later(MillenniumAnnouncementJob, [user.id], { + waitUntil: new Date(3000, 0, 1, 0, 0, 0), +}) +``` + +If we were to query the `BackgroundJob` table after the job has been scheduled you'd see a new row. We can use the Redwood Console to query the table from the command line: + +```js +% yarn rw console +> db.backgroundJob.findMany() +[ + { + id: 1, + attempts: 0, + handler: '{"name":"SendWelcomeEmailJob",path:"SendWelcomeEmailJob/SendWelcomeEmailJob","args":[335]}', + queue: 'default', + priority: 50, + runAt: 2024-07-12T22:27:51.085Z, + lockedAt: null, + lockedBy: null, + lastError: null, + failedAt: null, + createdAt: 2024-07-12T22:27:51.125Z, + updatedAt: 2024-07-12T22:27:51.125Z + } +] +``` + +:::info + +Because we're using the `PrismaAdapter` here all jobs are stored in the database, but if you were using a different storage mechanism via a different adapter you would have to query those in a manner specific to that adapter's backend. + +::: + +The `handler` column contains the name of the job, file path to find it, and the arguments its `perform()` function will receive. Where did the `name` and `path` come from? We have a babel plugin that adds them to your job when they are built! + +:::warning Jobs Must Be Built + +Jobs are run from the `api/dist` directory, which will exist only after running `yarn rw build api` or `yarn rw dev`. If you are working on a job in development, you're probably running `yarn rw dev` anyway. But just be aware that if the dev server is _not_ running then any changes to your job will not be reflected unless you run `yarn rw build api` (or start the dev server) to compile your job into `api/dist`. + +::: + +### Executing Jobs + +In development you can start a job worker via the **job runner** from the command line: + +```bash +yarn rw jobs work +``` + +The runner is a sort of overseer that doesn't do any work itself, but spawns workers to actually execute the jobs. When starting in `work` mode your `workers` config will be used to start the workers and they will stay attached to the terminal, updating you on the status of what they're doing: + +![image](/img/background-jobs/jobs-terminal.png) + +It checks the `BackgroundJob` table every few seconds for a new job and, if it finds one, locks it so that no other workers can have it, then calls your `perform()` function, passing it the arguments you gave when you scheduled it. + +If the job succeeds then by default it's removed from the database (using the `PrismaAdapter`, other adapters behavior may vary). If the job fails, the job is un-locked in the database, the `runAt` is set to an incremental backoff time in the future, and `lastError` is updated with the error that occurred. The job will now be picked up in the future once the `runAt` time has passed and it'll try again. + +To stop the runner (and the workers it started), press `Ctrl-C` (or send `SIGINT`). The workers will gracefully shut down, waiting for their work to complete before exiting. If you don't wait to wait, hit `Ctrl-C` again (or send `SIGTERM`). + +There are a couple of additional modes that `rw jobs` can run in: + +```bash +yarn rw jobs workoff +``` + +This mode will execute all jobs that are eligible to run, then stop itself. + +```bash +yarn rw jobs start +``` + +Starts the workers and then detaches them to run forever. Use `yarn rw jobs stop` to stop them, or `yarn rw jobs restart` to pick up any code changes to your jobs. + +### Everything Else + +The rest of this doc describes more advanced usage, like: + +- Assigning jobs to named **queues** +- Setting a **priority** so that some jobs always run before others +- Using different adapters and loggers on a per-job basis +- Starting more than one worker +- Having some workers focus on only certain queues +- Configuring individual workers to use different adapters +- Manually start workers without the job runner monitoring them +- And more! + +## Instantly Running Jobs + +As noted in the [Concepts](#concepts) section, a job is never _guaranteed_ to run at an exact time. The worker could be busy working on other jobs and can't get to yours just yet. + +If you absolutely, positively need your job to run right _now_ (with the knowledge that the user will be waiting for it to complete) you can call your job's `perform` function directly in your code: + +```js +await SampleEmailJob.perform(user.id) +``` + +## Recurring Jobs + +A common task for a background job is that it does something on a schedule: run reports every night at midnight, check for abandoned carts every 15 minutes, that sort of thing. We call these recurring jobs. + +Redwood's job system will soon have native syntax for setting a job to run repeatedly, but in the meantime you can accomplish this by simply having your job schedule another copy of itself at some interval in the future: + +```js +import { later, jobs } from 'src/lib/jobs' + +export const NightlyReportJob = jobs.createJob({ + queue: 'default', + perform: async () => { + await DailyUsageReport.run() + // highlight-start + await later(NightlyReportJob, [], { + wait: new Date(new Date().getTime() + 86_400 * 1000), + }) + // highlight-end + }, +}) +``` + +## Configuration + +There are a bunch of ways to customize your jobs and the workers. + +### JobManager Config + +Let's take a closer look at the `jobs` export in `api/src/lib/jobs.js`: + +```js +export const jobs = new JobManager({ + adapters: { + prisma: new PrismaAdapter({ db, logger }), + }, + queues: ['default'], + logger, + workers: [ + { + adapter: 'prisma', + logger, + queue: '*', + count: 1, + maxAttempts: 24, + maxRuntime: 14_400, + deleteFailedJobs: false, + sleepDelay: 5, + }, + ], +}) +``` + +The object passed here contains all of the configuration for the Background Job system. Let's take a quick look at the four top-level properties and then we'll get into more details in the subsections to follow. + +#### `adapters` + +This is the list of adapters that are available to handle storing and retrieving your jobs to and from the storage system. You could list more than one adapter here and then have multiple schedulers. Most folks will probably stick with a single one. + +#### `queues` + +An array of available queue names that jobs can be placed in. By default, a single queue named "default" is listed here, and will also be the default queue for generated jobs. To denote the named queue that a worker will look at, there is a matching `queue` property on the `workers` config below. + +#### `logger` + +The logger object for all internal logging of the job system itself and will fall back to `console` if you don't set it. + +#### `workers` + +This is an array of objects, each defining a "group" of workers. When will you need more than one group? If you need workers to work on different queues, or use different adapters. Read more about this in the [Job Workers](#job-workers) section. + +### Adapter Config + +Adapters are added as key/value pairs to the `adapters` object given to the `JobManager` upon initialization. The key of the property (like `prisma` in the example below) is the name you'll use in your scheduler when you tell it which adapter to use to schedule your jobs. Adapters accept an object of options when they are initialized. + +#### PrismaAdapter + +```js +export const jobs = new JobManager({ + adapters: { + // highlight-next-line + prisma: new PrismaAdapter({ db, model: 'BackgroundJob', logger }), + }, + // remaining config... +}) +``` + +- `db`: **[required]** an instance of `PrismaClient` that the adapter will use to store, find and update the status of jobs. In most cases this will be the `db` variable exported from `api/src/lib/db.{js,ts}`. This must be set in order for the adapter to be initialized! +- `model`: the name of the model that was created to store jobs. This defaults to `BackgroundJob`. +- `logger`: events that occur within the adapter will be logged using this. This defaults to `console` but the `logger` exported from `api/src/lib/logger` works great. + +### Scheduler Config + +When you create an instance of the scheduler you can pass it a couple of options: + +```js +export const later = jobs.createScheduler({ + adapter: 'prisma', +}) +``` + +- `adapter` : **[required]** the name of the adapter this scheduler will use to schedule jobs. Must be one of the keys that you gave to the `adapters` option on the JobManager itself. +- `logger` : the logger to use for this instance of the scheduler. If not provided, defaults to the `logger` set on the `JobManager`. + +#### Scheduling Options + +When using the scheduler to schedule a job you can pass options in an optional third argument: + +```js +later(SampleJob, [user.id], { wait: 300 }) +``` + +- `wait`: number of seconds to wait before the job will run +- `waitUntil`: a specific `Date` in the future to run at + +If you don't pass any options then the job will be defaulted to run as soon as possible, ie: `new Date()` + +### Job Config + +There are two configuration options you can define in the object that describes your job: + +```js +import { jobs } from 'src/lib/jobs' + +export const SendWelcomeEmailJob = jobs.createJob({ + // highlight-start + queue: 'email', + priority: 1, + // highlight-end + perform: async (userId) => { + // job details... + }, +}) +``` + +- `queue` : **[required]** the name of the queue that this job will be placed in. Must be one of the strings you assigned to the `queues` array when you set up the `JobManager`. +- `priority` : within a queue you can have jobs that are more or less important. The workers will pull jobs off the queue with a higher priority before working on ones with a lower priority. A lower number is _higher_ in priority than a higher number. Ie. the workers will work on a job with a priority of `1` before they work on one with a priority of `100`. If you don't override it here, the default priority is `50`. + +### Worker Config + +This is the largest section of the `JobManager` config object. This options array tell the workers how to behave when looking for and executing jobs. + +```js +export const jobs = new JobManager({ + // .. more config + workers: [ + { + adapter: 'prisma', + logger, + queue: '*', + count: 1, + maxAttempts: 24, + maxRuntime: 14_400, + deleteFailedJobs: true, + deleteSuccessfulJobs: false, + sleepDelay: 5, + }, + ], + +``` + +This is an array of objects. Each object represents the config for a single "group" of workers. By default, there is only one worker group. It uses the `PrismaAdapter` and will look for jobs in all queues. If you want to start fine tuning your workers by working with different adapters, or only working on some named queues, you can add additional members to this array, each with a unique set of options. + +- `adapter` : **[required]** the name of the adapter this worker group will use. Must be one of the keys that you gave to the `adapters` option on the `JobManager` itself. +- `logger` : the logger to use when working on jobs. If not provided, defaults to the `logger` set on the `JobManager`. You can use this logger in the `perform()` function of your job by accessing `jobs.logger` +- queue : **[required]** the named queue(s) in which this worker group will watch for jobs. There is a reserved `'*'` value you can use which means "all queues." This can be an array of queues as well: `['default', 'email']` for example. +- `count` : **[required]** the number of workers to start with this config. +- `maxAttempts`: the maximum number of times to retry a job before giving up. A job that throws an error will be set to retry in the future with an exponential backoff in time equal to the number of previous attempts \*\* 4. After this number, a job is considered "failed" and will not be re-attempted. Default: `24`. +- `maxRuntime` : the maximum amount of time, in seconds, to try running a job before another worker will pick it up and try again. It's up to you to make sure your job doesn't run for longer than this amount of time! Default: `14_400` (4 hours). +- `deleteFailedJobs` : when a job has failed (maximum number of retries has occurred) you can keep the job in the database, or delete it. Default: `false`. +- `deleteSuccessfulJobs` : when a job has succeeded, you can keep the job in the database, or delete it. It's generally assumed that your jobs _will_ succeed so it usually makes sense to clear them out and keep the queue lean. Default: `true`. +- `sleepDelay` : the amount of time, in seconds, to wait before checkng the queue for another job to run. Too low and you'll be thrashing your storage system looking for jobs, too high and you start to have a long delay before any job is run. Default: `5`. + +See the next section for advanced usage examples, like multiple worker groups. + +## Job Workers + +A job worker actually executes your jobs. The workers will ask the adapter to find a job to work on. The adapter will mark the job as locked (the process name and a timestamp is set on the job) and then the worker will call `perform()` on your job, passing in any args that were given when you scheduled it. The behavior of what happens when the job succeeds or fails depends on the config options you set in the `JobManager`. By default, successful jobs are removed from storage and failed jobs and kept around so you can diagnose what happened. + +The runner has several modes it can start in depending on how you want it to behave. + +### Dev Modes + +These modes are ideal when you're creating a job and want to be sure it runs correctly while developing. You could also use this in production if you wanted (maybe a job is failing and you want to watch verbose logs and see what's happening). + +```bash +yarn rw jobs work +``` + +This process will stay attached to the console and continually look for new jobs and execute them as they are found. The log level is set to `debug` by default so you'll see everything. Pressing `Ctrl-C` to cancel the process (sending `SIGINT`) will start a graceful shutdown: the workers will complete any work they're in the middle of before exiting. To cancel immediately, hit `Ctrl-C` again (or send `SIGTERM`) and they'll stop in the middle of what they're doing. Note that this could leave locked jobs in the database, but they will be picked back up again if a new worker starts with the same name as the one that locked the process. They'll also be picked up automatically after `maxRuntime` has expired, even if they are still locked. + +:::caution Long running jobs + +It's currently up to you to make sure your job completes before your `maxRuntime` limit is reached! NodeJS Promises are not truly cancelable: you can reject early, but any Promises that were started _inside_ will continue running unless they are also early rejected, recursively forever. + +The only way to guarantee a job will completely stop no matter what is for your job to spawn an actual OS level process with a timeout that kills it after a certain amount of time. We may add this functionality natively to Jobs in the near future: let us know if you'd benefit from this being built in! + +::: + +To work on whatever outstanding jobs there are and then automatically exit use the `workoff` mode: + +```bash +yarn rw jobs workoff +``` + +As soon as there are no more jobs to be executed (either the store is empty, or they are scheduled in the future) the process will automatically exit. + +### Clearing the Job Queue + +You can remove all jobs from storage with: + +```bash +yarn rw jobs clear +``` + +### Production Modes + +In production you'll want your job workers running forever in the background. For that, use the `start` mode: + +```bash +yarn rw jobs start +``` + +That will start a number of workers determined by the `workers` config on the `JobManager` and then detach them from the console. If you care about the output of that worker then you'll want to have configured a logger that writes to the filesystem or sends to a third party log aggregator. + +To stop the workers: + +```bash +yarn rw jobs stop +``` + +Or to restart any that are already running: + +```bash +yarn rw jobs restart +``` + +### Multiple Workers + +With the default configuration options generated with the `yarn rw setup jobs` command you'll have one worker group. If you simply want more workers that use the same `adapter` and `queue` settings, increase the `count`: + +```js +export const jobs = new JobManager({ + adapters: { + prisma: new PrismaAdapter({ db, logger }), + }, + queues: ['default'], + logger, + workers: [ + { + adapter: 'prisma', + logger, + queue: '*', + // highlight-next-line + count: 5, + maxAttempts: 24, + maxRuntime: 14_400, + deleteFailedJobs: false, + sleepDelay: 5, + }, + ], +}) +``` + +Now you have 5 workers. If you want to have separate workers working on separate queues, create another worker config object with a different queue name: + +```js +export const jobs = new JobManager({ + adapters: { + prisma: new PrismaAdapter({ db, logger }), + }, + queues: ['default'], + logger, + workers: [ + { + adapter: 'prisma', + logger, + // highlight-start + queue: 'default', + // highlight-end + count: 1, + maxAttempts: 24, + maxRuntime: 14_400, + deleteFailedJobs: false, + sleepDelay: 5, + }, + { + adapter: 'prisma', + logger, + // highlight-start + queue: 'email', + count: 1, + maxAttempts: 1, + maxRuntime: 30, + deleteFailedJobs: true, + // highlight-end + sleepDelay: 5, + }, + ], +}) +``` + +Here, we have 2 workers working on the "default" queue and 1 worker looking at the "email" queue (which will only try a job once, wait 30 seconds for it to finish, and delete the job if it fails). You can also have different worker groups using different adapters. For example, you may store and work on some jobs in your database using the `PrismaAdapter` and some jobs/workers using a `RedisAdapter`. + +:::info + +We don't currently provide a `RedisAdapter` but plan to add one soon! You'll want to create additional schedulers to use any other adapters as well: + +```js +export const prismaLater = jobs.createScheduler({ + adapter: 'prisma', +}) + +export const redisLater = jobs.createScheduler({ + adapter: 'redis', +}) +``` + +::: + +## Job Errors & Failure + +Jobs sometimes don't complete as expected, either because of an error in our code (unlikely, of course) or because a third party service that's being accessed responds in an unexpected way. Luckily, the job system is ready to handle these problems gracefully. + +If you're using the `PrismaAdapter` and an uncaught error occurs while the worker is executing your `perform` function, three things happen: + +1. The job's `runAt` time is set to a new time in the future, based on an incremental backoff computed from the number of previous attempts at running the job (by default it's `attempts ** 4`) +2. The error message and backtrace is recorded in the `lastError` field +3. The job is unlocked so that it's available for another worker to pick up when the time comes + +By checking the `lastError` field in the database you can see what the last error was and attempt to correct it, if possible. If the retry occurs and another error is thrown, the same sequence above will happen _unless_ the number of attempts is equal to the `maxAttempts` config variable set in the jobs config. If `maxAttempts` is reached then the job is considered **failed** and will not be rescheduled. `runAt` is set to `NULL`, the `failedAt` timestamp is set to now and, assuming you have `deleteFailedJobs` set to `false`, the job will remain in the database so you can inspect it and potentially correct the problem. + +## Deployment + +For many use cases you may simply be able to rely on the job runner to start your job workers, which will run forever: + +```bash +yarn rw jobs start +``` + +When you deploy new code you'll want to restart your runners to make sure they get the latest source files: + +```bash +yarn rw jobs restart +``` + +Using this utility, however, gives you nothing to monitor that your jobs workers are still running: the runner starts the required number of workers, detaches them, and then exits itself. Node processes are pretty robust, but by no means are they guaranteed to run forever with no problems. You could mistakenly release a bad job that has an infinite loop or even just a random gamma ray striking the RAM of the server could cause a panic and the process will be shut down. + +For maximum reliability you should take a look at the [Advanced Job Workers](#advanced-job-workers) section and manually start your workers this way, with a process monitor like [pm2](https://pm2.keymetrics.io/) or [nodemon](https://github.com/remy/nodemon) to watch and restart the workers if something unexpected happens. + +:::info + +Of course if you have a process monitor system watching your workers you'll want to use the process monitor's version of the `restart` command each time you deploy! + +::: + +## Advanced Job Workers + +As noted above, although the workers are started and detached using the `yarn rw jobs start` command, there is nothing to monitor those workers to make sure they keep running. To do that, you'll want to start the workers yourself (or have your process monitor start them) using command line flags. + +You can do this with the `yarn rw-jobs-worker` command. The flags passed to the script tell it which worker group config to use to start itself, and which `id` to give this worker (if you're running more than one). To start a single worker, using the first `workers` config object, you would run: + +```bash +yarn rw-jobs-worker --index=0 --id=0 +``` + +:::info + +The job runner started with `yarn rw jobs start` runs this same command behind the scenes for you, keeping it attached or detached depending on if you start in `work` or `start` mode! + +::: + +### Flags + +- `--index` : a number that represents the index of the `workers` config array you passed to the `JobManager`. Setting this to `0`, for example, uses the first object in the array to set all config options for the worker. +- `--id` : a number identifier that's set as part of the process name. Starting a worker with `--id=0` and then inspecting your process list will show one worker running named `rw-job-worker.queue-name.0`. Using `yarn rw-jobs-worker` only ever starts a single instance, so if your config had a `count` of `2` you'd need to run the command twice, once with `--id=0` and a second time with `--id=1`. +- `--workoff` : a boolean that will execute all currently available jobs and then cause the worker to exit. Defaults to `false` +- `--clear` : a boolean that starts a worker to remove all jobs from all queues. Defaults to `false` + +Your process monitor can now restart the workers automatically if they crash since the monitor is using the worker script itself and not the wrapping job runner. + +### What Happens if a Worker Crashes? + +If a worker crashes because of circumstances outside of your control the job will remained locked in the storage system: the worker couldn't finish work and clean up after itself. When this happens, the job will be picked up again immediately if a new worker starts with the same process title, otherwise when `maxRuntime` has passed it's eligible for any worker to pick up and re-lock. + +## Creating Your Own Adapter + +We'd love the community to contribute adapters for Redwood Jobs! Take a look at the source for `BaseAdapter` for what's absolutely required, and then the source for `PrismaAdapter` to see a concrete implementation. + +The general gist of the required functions: + +- `find()` should find a job to be run, lock it and return it (minimum return of an object containing `id`, `name`, `path`, `args` and `attempts` properties) +- `schedule()` accepts `name`, `path`, `args`, `runAt`, `queue` and `priority` and should store the job +- `success()` accepts the same job object returned from `find()` and a `deleteJob` boolean for whether the job should be deleted upon success. +- `error()` accepts the same job object returned from `find()` and an error instance. Does whatever failure means to you (like unlock the job and reschedule a time for it to run again in the future) +- `failure()` is called when the job has reached `maxAttempts`. Accepts the job object and a `deleteJob` boolean that says whether the job should be deleted. +- `clear()` remove all jobs from the queue (mostly used in development). + +## The Future + +There's still more to add to background jobs!

The root query in `QUERY` is the same as `` so that, if you're generating a cell based on a model in your `schema.prisma`, you can get something out of the database right away. But there's a good chance you won't generate your Cell this way, so if you need to, make sure to change the root query. See the [Cells](tutorial/chapter2/cells.md#our-first-cell) section of the Tutorial for a great example of this. + +## Usage + +With Cells, you have a total of seven exports to work with: + +| Name | Type | Description | +| :------------ | :---------------- | :----------------------------------------------------------- | +| `QUERY` | `string,function` | The query to execute | +| `beforeQuery` | `function` | Lifecycle hook; prepares variables and options for the query | +| `isEmpty` | `function` | Lifecycle hook; decides if the Cell should render Empty | +| `afterQuery` | `function` | Lifecycle hook; sanitizes data returned from the query | +| `Loading` | `component` | If the request is in flight, render this component | +| `Empty` | `component` | If there's no data (`null` or `[]`), render this component | +| `Failure` | `component` | If something went wrong, render this component | +| `Success` | `component` | If the data has loaded, render this component | + +Only `QUERY` and `Success` are required. If you don't export `Empty`, empty results are sent to `Success`, and if you don't export `Failure`, error is output to the console. + +In addition to displaying the right component at the right time, Cells also funnel the right props to the right component. `Loading`, `Empty`, `Failure`, and `Success` all have access to the props passed down from the Cell in good ol' React fashion, and most of the `useQuery` hook's return as a prop called `queryResult`. In addition to all those props, `Empty` and `Success` also get the `data` returned from the query and an `updating` prop indicating whether the Cell is currently fetching new data. `Failure` also gets `updating` and exclusive access to `error` and `errorCode`. + +We mentioned above that Cells receive "most" of what's returned from the `useQuery` hook. You can see exactly what `useQuery` returns in Apollo Client's [API reference](https://www.apollographql.com/docs/react/api/react/hooks/#result). Again note that `error` and `data` get some special treatment. + +### QUERY + +`QUERY` can be a string or a function. If `QUERY` is a function, it has to return a valid GraphQL document. + +It's more-than ok to have more than one root query. Here's an example: + +```jsx {7-10} +export const QUERY = gql`{ + query { + posts { + id + title + } + authors { + id + name + } + } +} +``` + +So in this case, both `posts` and `authors` would be available to `Success`: + +```jsx +export const Success = ({ posts, authors }) => { + // ... +} +``` + +Normally queries have variables. Cells are setup to use any props they receive from their parent as variables (things are setup this way in `beforeQuery`). For example, here `BlogPostCell` takes a prop, `numberToShow`, so `numberToShow` is just available to your `QUERY`: + +```jsx {7} +import BlogPostsCell from 'src/components/BlogPostsCell' + +const HomePage = () => { + return ( +
+

Home

+ +
+ ) +} + +export default HomePage +``` + +```jsx {2-3} +export const QUERY = gql` + query ($numberToShow: Int!) { + posts(numberToShow: $numberToShow) { + id + title + } + } +` +``` + +This means you can think backwards about your Cell's props from your SDL: whatever the variables in your SDL are, that's what your Cell's props should be. + +### beforeQuery + +`beforeQuery` is a lifecycle hook. The best way to think about it is as a chance to configure [Apollo Client's `useQuery` hook](https://www.apollographql.com/docs/react/api/react/hooks#options). + +By default, `beforeQuery` gives any props passed from the parent component to `QUERY` so that they're available as variables for it. It'll also set the fetch policy to `'cache-and-network'` since we felt it matched the behavior users want most of the time: + +```jsx +export const beforeQuery = (props) => { + return { + variables: props, + fetchPolicy: 'cache-and-network', + } +} +``` + +For example, if you wanted to turn on Apollo's polling option, and prevent caching, you could export something like this (see Apollo's docs on [polling](https://www.apollographql.com/docs/react/data/queries/#polling) and [caching](https://www.apollographql.com/docs/react/data/queries/#setting-a-fetch-policy)) + +```jsx +export const beforeQuery = (props) => { + return { variables: props, fetchPolicy: 'no-cache', pollInterval: 2500 } +} +``` + +You can also use `beforeQuery` to populate variables with data not included in the Cell's props (like from React's Context API or a global state management library). If you provide a `beforeQuery` function, the Cell will automatically change the type of its props to match the first argument of the function. + +```jsx +// The Cell will take no props: +export const beforeQuery = () => { + const { currentUser } = useAuth() + + return { + variables: { userId: currentUser.id }, + } +} +``` + +```jsx +// The cell will take 1 prop named "word" that is a string: +export const beforeQuery = ({ word }: { word: string }) => { + return { + variables: { magicWord: word } + } +} +``` + +### isEmpty + +`isEmpty` is an optional lifecycle hook. It returns a boolean to indicate if the Cell should render empty. Use it to override the default check, which checks if the Cell's root fields are null or empty arrays. + +It receives two parameters: 1) the `data`, and 2) an object that has the default `isEmpty` function, named `isDataEmpty`, so that you can extend the default: + +```jsx +export const isEmpty = (data, { isDataEmpty }) => { + return isDataEmpty(data) || data?.blog?.status === 'hidden' +} +``` + +### afterQuery + +`afterQuery` is a lifecycle hook. It runs just before data gets to `Success`. +Use it to sanitize data returned from `QUERY` before it gets there. + +By default, `afterQuery` just returns the data as it is: + +### Loading + +If there's no cached data and the request is in flight, a Cell renders `Loading`. + +When you're developing locally, you can catch your Cell waiting to hear back for a moment if set your speed in the Inspector's **Network** tab to something like "Slow 3G". + +But why bother with Slow 3G when Redwood comes with Storybook? Storybook makes developing components like `Loading` (and `Failure`) a breeze. We don't have to put up with hacky workarounds like Slow 3G or intentionally breaking our app just to develop our components. + +### Empty + +A Cell renders this component if there's no data. +By no data, we mean if the response is 1) `null` or 2) an empty array (`[]`). + +### Failure + +A Cell renders this component if something went wrong. You can quickly see this in action if you add an untyped field to your `QUERY`: + +```jsx {6} +const QUERY = gql` + query { + posts { + id + title + unTypedField + } + } +` +``` + +But, like `Loading`, Storybook is probably a better place to develop this. + + + +In this example, we use the `errorCode` to conditionally render the error heading title, and we also use it for our translation string. + +```jsx +export const Failure = ({ error, errorCode }: CellFailureProps) => { + const { t } = useTranslation() + return ( +
+ {errorCode === 'NO_CONFIG' ?

NO_CONFIG

:

ERROR

} + Error: {error.message} - Code: {errorCode} - {t(`error.${errorCode}`)} +
+ ) +} +``` + +### Success + +If everything went well, a Cell renders `Success`. + +As mentioned, Success gets exclusive access to the `data` prop. But if you try to destructure it from `props`, you'll notice that it doesn't exist. This is because Redwood adds a layer of convenience: Redwood spreads `data` into `Success` so that you can just destructure whatever data you were expecting from your `QUERY` directly. + +So, if you're querying for `posts` and `authors`, instead of doing: + +```jsx +export const Success = ({ data }) => { + const { posts, authors } = data + + // ... +} +``` + +Redwood lets you do: + +```jsx +export const Success = ({ posts, authors }) => { + // ... +} +``` + +Note that you can still pass any other props to `Success`. After all, it's just a React component. + +:::tip + +Looking for info on how TypeScript works with Cells? Check out the [Utility Types](typescript/utility-types.md#cells) doc. + +::: + +### When should I use a Cell? + +Whenever you want to fetch data. Let Redwood juggle what's displayed when. You just focus on what those things should look like. + +While you can use a Cell whenever you want to fetch data, it's important to note that you don't have to. You can do anything you want! For example, for one-off queries, there's always `useApolloClient`. This hook returns the client, which you can use to execute queries, among other things: + +```jsx +// In a react component... + +client = useApolloClient() + +client.query({ + query: gql` + ... + `, +}) +``` + +### Can I Perform a Mutation in a Cell? + +Absolutely. We do so in our [example todo app](https://github.com/redwoodjs/example-todo/blob/f29069c9dc89fa3734c6f99816442e14dc73dbf7/web/src/components/TodoListCell/TodoListCell.js#L26-L44). +We also don't think it's an anti-pattern to do so. Far from it—your cells might end up containing a lot of logic and really serve as the hub of your app in many ways. + +It's also important to remember that, besides exporting certain things with certain names, there aren't many rules around Cells—everything you can do in a regular component still goes. + +## How Does Redwood Know a Cell is a Cell? + +You just have to end a filename in "Cell" right? Well, while that's basically correct, there is one other thing you should know. + +Redwood looks for all files ending in "Cell" (so if you want your component to be a Cell, its filename does have to end in "Cell"), but if the file 1) doesn't export a const named `QUERY` and 2) has a default export, then it'll be skipped. + +When would you want to do this? If you just want a file to end in "Cell" for some reason. Otherwise, don't worry about it! + + + + + + +## Advanced Example: Implementing a Cell Yourself + +If we didn't do all that build-time stuff for you, how might you go about implementing a Cell yourself? + +Consider the [example from the Tutorial](tutorial/chapter2/cells.md#our-first-cell) where we're fetching posts: + +```jsx +export const QUERY = gql` + query { + posts { + id + title + body + createdAt + } + } +` + +export const Loading = () =>
Loading...
+ +export const Empty = () =>
No posts yet!
+ +export const Failure = ({ error }) => ( +
Error loading posts: {error.message}
+) + +export const Success = ({ posts }) => { + return posts.map((post) => ( +
+

{post.title}

+
{post.body}
+
+ )) +} +``` + +And now let's say that Babel isn't going to come along and assemble our exports. What might we do? + +We'd probably do something like this: + + + +```jsx +const QUERY = gql` + query { + posts { + id + title + body + createdAt + } + } +` + +const Loading = () =>
Loading...
+ +const Empty = () =>
No posts yet!
+ +const Failure = ({ error }) => ( +
Error loading posts: {error.message}
+) + +const Success = ({ posts }) => { + return posts.map((post) => ( +
+

{post.title}

+
{post.body}
+
+ )) +} + +const isEmpty = (data) => { + return isDataNull(data) || isDataEmptyArray(data) +} + +export const Cell = () => { + return ( + + {({ error, loading, data }) => { + if (error) { + if (Failure) { + return + } else { + console.error(error) + } + } else if (loading) { + return + } else if (data) { + if (typeof Empty !== 'undefined' && isEmpty(data)) { + return + } else { + return + } + } else { + throw 'Cannot render Cell: graphQL success but `data` is null' + } + }} + + ) +} +``` + +That's a lot of code. A lot of imperative code too. + +We're basically just dumping the contents of [createCell.tsx](https://github.com/redwoodjs/redwood/blob/main/packages/web/src/components/cell/createCell.tsx) into this file. Can you imagine having to do this every time you wanted to fetch data that might be delayed in responding?

I.e. errors in the function needed for the GraphQL server, but also other serverless functions. + +The main reason for this is that these Netlify CLI commands simply build and deploy -- they build your project locally and then push the dist folder. That means that when building a RedwoodJS project, the [Prisma client is generated with binaries matching the operating system at build time](https://cli.netlify.com/commands/link) -- and not the [OS compatible](https://www.prisma.io/docs/reference/api-reference/prisma-schema-reference#binarytargets-options) with running functions on Netlify.

Prisma Migrate lets you use Prisma schema to make changes to your database declaratively, all while keeping things deterministic and fully customizable by generating the migration steps in a simple, familiar format: SQL. + +Since migrate generates plain SQL files, you can edit those SQL files before applying the migration using `yarn redwood prisma migrate --create-only`. This creates the migration based on the changes in the Prisma schema, but doesn't apply it, giving you the chance to go in and make any modifications you want. [Daniel Norman's tour of Prisma Migrate](https://www.youtube.com/watch?v=0LKhksstrfg) demonstrates this and more to great effect. + +Prisma Migrate has separate commands for applying migrations based on whether you're in dev or in production.

It supports MySQL and Postgres databases in either the U.S. or EU regions. + +To set up a Prisma Data Proxy, sign up for the [Prisma Data Platform](https://www.prisma.io/data-platform) for free. In your onboarding workflow, plug in the connection URL for your database and choose your region. This will generate a connection string for your app. Then follow the instructions in [Prisma's documentation](https://www.prisma.io/docs/concepts/data-platform/data-proxy). + +> Note that the example uses npm. Rather than using npm, you can access the Prisma CLI using `yarn redwood prisma` inside a Redwood app. + +## Prisma & PgBouncer + +PgBouncer holds a connection pool to the database and proxies incoming client connections by sitting between Prisma Client and the database. This reduces the number of processes a database has to handle at any given time. PgBouncer passes on a limited number of connections to the database and queues additional connections for delivery when space becomes available. + +To use Prisma Client with PgBouncer from a serverless function, add the `?pgbouncer=true` flag to the PostgreSQL connection URL: + +``` +postgresql://USER:PASSWORD@HOST:PORT/DATABASE?pgbouncer=true +``` + +Typically, your PgBouncer port will be 6543 which is different from the Postgres default of 5432. + +> Note that since Prisma Migrate uses database transactions to check out the current state of the database and the migrations table, if you attempt to run Prisma Migrate commands in any environment that uses PgBouncer for connection pooling, you might see an error. +> +> To work around this issue, you must connect directly to the database rather than going through PgBouncer when migrating. + +For more information on Prisma and PgBouncer, please refer to Prisma's Guide on [Configuring Prisma Client with PgBouncer](https://www.prisma.io/docs/guides/performance-and-optimization/connection-management/configure-pg-bouncer). + +## Supabase + +For Postgres running on [Supabase](https://supabase.io) see: [PgBouncer is now available in Supabase](https://supabase.io/blog/2021/04/02/supabase-pgbouncer#using-connection-pooling-in-supabase). + +All new Supabase projects include connection pooling using [PgBouncer](https://www.pgbouncer.org/). + +We recommend that you connect to your Supabase Postgres instance using SSL which you can do by setting `sslmode` to `require` on the connection string: + +``` +// not pooled typically uses port 5432 +postgresql://postgres:mydb.supabase.co:5432/postgres?sslmode=require +// pooled typically uses port 6543 +postgresql://postgres:mydb.supabase.co:6543/postgres?sslmode=require&pgbouncer=true +``` + +## Heroku + +For Postgres, see [Postgres Connection Pooling](https://devcenter.heroku.com/articles/postgres-connection-pooling). + +Heroku does not officially support MySQL. + +## Digital Ocean + +For Postgres, see [How to Manage Connection Pools](https://www.digitalocean.com/docs/databases/postgresql/how-to/manage-connection-pools) + +To run migrations through a connection pool, you're required to append connection parameters to your `DATABASE_URL`.

If omitted, you may receive the following error: + +``` +Error: Migration engine error: +db error: ERROR: prepared statement "s0" already exists +``` + +To resolve this, use the following structure in your `DATABASE_URL`: + +``` +:25061/defaultdb?connection_limit=3&sslmode=require&pgbouncer=true&connect_timeout=10&pool_timeout=30 +``` + +Here's a couple more things to be aware of: + +- When using a Digital Ocean connection pool, you'll have multiple ports available. Typically the direct connection (without connection pooling) is on port `25060` and the connection through pgbouncer is served through port `25061`. Make sure you connect to your connection pool on port `25061` +- Adjust the `connection_limit`. Clusters provide 25 connections per 1 GB of RAM. Three connections per cluster are reserved for maintenance, and all remaining connections can be allocated to connection pools +- Both `pgbouncer=true` and `pool_timeout=30` are required to deploy successfully through your connection pool + +Connection Pooling for MySQL is not yet supported. + +## AWS + +Use [Amazon RDS Proxy](https://aws.amazon.com/rds/proxy) for MySQL or PostgreSQL. + +From the [AWS Docs](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-proxy.html#rds-proxy.limitations): + +> Your RDS Proxy must be in the same VPC as the database. The proxy can't be publicly accessible. + +Because of this limitation, with out-of-the-box configuration, you can only use RDS Proxy if you're deploying your Lambda Functions to the same AWS account. Alternatively, you can use RDS directly, but you might require larger instances to handle your production traffic and the number of concurrent connections. + +## Why Connection Pooling? + +Relational databases have a maximum number of concurrent client connections. + +- Postgres allows 100 by default +- MySQL allows 151 by default + +In a traditional server environment, you would need a large amount of traffic (and therefore web servers) to exhaust these connections, since each web server instance typically leverages a single connection. + +In a Serverless environment, each function connects directly to the database, which can exhaust limits quickly. To prevent connection errors, you should add a connection pooling service in front of your database.

Our community mantra is **“By helping each other be successful with Redwood, we make the Redwood project successful.”** We have a specific vision for the effect this project and community will have on you — it should give you superpowers to build+create, progress in skills, and help advance your career. + +So who do you need to become to achieve this? Specifically, what characteristics, skills, and capabilities will you need to cultivate through practice? Here are our suggestions: + +- Empathy +- Gratitude +- Generosity + +All of these are applicable in relation to both others and yourself. The goal of putting them into practice is to create trust that will be a catalyst for risk-taking (another word to describe this process is “learning”!). These are the ingredients necessary for productive, positive collaboration. + +And you thought all this was just about opening a PR 🤣 Yes, it’s a super rewarding experience. But that’s just the beginning! + +## What should I work on? + +Even if you know the mechanics, it’s hard to get started without a starting place. Our best advice is this — dive into the Redwood Tutorial, read the docs, and build your own experiment with Redwood. Along the way, you’ll find typos, out-of-date (or missing) documentation, code that could work better, or even opportunities for improving and adding features. You’ll be engaging in the Forums and Chat and developing a feel for priorities and needs. This way, you’ll naturally follow your own interests and sooner than later intersect “things you’re interested in” + “ways to help improve Redwood”. + +There are other more direct ways to get started as well, which are outlined below. + +### Project Boards and GitHub Issues + +The Redwood Core Team is working publicly — progress is updated daily on the [Release Project Board](https://github.com/orgs/redwoodjs/projects/11). + +Eventually, all this leads you back to Redwood’s GitHub Issues page. Here you’ll find open items that need help, which are organized by labels. There are four labels helpful for contributing: + +1. [Good First Issue](https://github.com/redwoodjs/redwood/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22): these items are more likely to be an accessible entry point to the Framework. It’s less about skill level and more about focused scope. +2. [Help Wanted](https://github.com/redwoodjs/redwood/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22): these items especially need contribution help from the community. +3. [Bugs 🐛](https://github.com/redwoodjs/redwood/issues?q=is%3Aissue+is%3Aopen+label%3Abug%2Fconfirmed): last but not least, we always need help with bugs. Some are technically less challenging than others. Sometimes the best way you can help is to attempt to reproduce the bug and confirm whether or not it’s still an issue. + +### Create a New Issue + +Anyone can create a new Issue. If you’re not sure that your feature or idea is something to work on, start the discussion with an Issue. Describe the idea and problem + solution as clearly as possible, including examples or pseudo code if applicable. It’s also very helpful to `@` mention a maintainer or Core Team member that shares the area of interest. + +Just know that there’s a lot of Issues that shuffle every day. If no one replies, it’s just because people are busy. Reach out in the Forums, Chat, or comment in the Issue. We intend to reply to every Issue that’s opened. If yours doesn’t have a reply, then give us a nudge! + +Lastly, it can often be helpful to start with brief discussion in the community Chat or Forums. Sometimes that’s the quickest way to get feedback and a sense of priority before opening an Issue. + +## Contributing Code + +Redwood's composed of many packages that are designed to work together. Some of these packages are designed to be used outside Redwood too! + +Before you start contributing, you'll want to set up your local development environment. The Redwood repo's top-level [contributing guide](https://github.com/redwoodjs/redwood/blob/main/CONTRIBUTING.md#local-development) walks you through this. Make sure to give it an initial read. + +For details on contributing to a specific package, see the package's README (links provided in the table below). Each README has a section named Roadmap. If you want to get involved but don't quite know how, the Roadmap's a good place to start. See anything that interests you? Go for it! And be sure to let us know—you don't have to have a finished product before opening an issue or pull request. In fact, we're big fans of [Readme Driven Development](https://tom.preston-werner.com/2010/08/23/readme-driven-development.html). + +What you want to do not on the roadmap? Well, still go for it!

Redwood prides itself on good developer experience, and that includes good documentation. + +Before you get started, there's an implicit doc-distinction that we should make explicit: all the docs on redwoodjs.com are for helping people develop apps using Redwood, while all the docs on the Redwood repo are for helping people contribute to Redwood. + +Although Developing and Contributing docs are in different places, they most definitely should be linked and referenced as needed. For example, it's appropriate to have a "Contributing" doc on redwoodjs.com that's context-appropriate, but it should link to the Framework's [CONTRIBUTING.md](https://github.com/redwoodjs/redwood/blob/main/CONTRIBUTING.md) (the way this doc does). + +### How Redwood Thinks about Docs + +Before we get into the how-to, a little explanation. When thinking about docs, we find [divio's documentation system](https://documentation.divio.com/) really useful. It's not necessary that a doc always have all four of the dimensions listed, but if you find yourself stuck, you can ask yourself questions like "Should I be explaining? Am I explaining too much? Too little?" to reorient yourself while writing. + +### Docs for Developing Redwood Apps + +redwoodjs.com has three kinds of Developing docs: References, How To's, and The Tutorial. +You can find References and How To's within their respective directories on the redwood/redwood repo: [docs/](https://github.com/redwoodjs/redwood/tree/main/docs) and [how-to/](https://github.com/redwoodjs/redwood/tree/main/docs/how-to). + +The Tutorial is a standalone document that serves a specific purpose as an introduction to Redwood, an aspirational roadmap, and an example of developer experience. As such, it's distinct from the categories mentioned, although it's most similar to How To's. + +#### References + +References are explanation-driven how-to content. They're more direct and to-the-point than The Tutorial and How To's. The idea is much more about finding something or getting something done than any kind of learning journey. + +Before you take on a doc, you should read [Forms](forms.md) and [Router](router.md); they have the kind of content you should be striving for. They're comprehensive yet conversational. + +In general, don't be afraid to go into too much detail. We'd rather you err on the side of too much than too little. One tip for finding good content is searching the forum and repo for "prior art"—what are people talking about where this comes up? + +#### How To's + +How To's are tutorial-style content focused on a specific problem-solution. They usually have a beginner in mind (if not, they should indicate that they don't—put 'Advanced' or 'Deep-Dive', etc., in the title or introduction). How To's may include some explanatory text as asides, but they shouldn't be the majority of the content. + +#### Making a Doc Findable + +If you write it, will they read it? We think they will—if they can find it. + +After you've finished writing, step back for a moment and consider the word(s) or phrase(s) people will use to find what you just wrote. For example, let's say you were writing a doc about configuring a Redwood app. If you didn't know much about configuring a Redwood app, a heading (in the nav bar to the left) like "redwood.toml" wouldn't make much sense, even though it _is_ the main configuration file. You'd probably look for "Redwood Config" or "Settings", or type "how to change Redwood App settings" in the "Search the docs" bar up top, or in Google. + +That is to say, the most useful headings aren't always the most literal ones. Indexing is more than just underlining the "important" words in a text—it's identifying and locating the concepts and topics that are the most relevant to our readers, the users of our documentation. + +So, after you've finished writing, reread what you wrote with the intention of making a list of two to three keywords or phrases. Then, try to use each of those in three places, in this order of priority: + +- the left-nav menu title +- the page title or the first right-nav ("On this page") section title +- the introductory paragraph + +### Docs for Contributing to the Redwood Repo + +These docs are in the Framework repo, redwoodjs/redwood, and explain how to contribute to Redwood packages. They're the docs linked to in the table above. + +In general, they should consist of more straightforward explanations, are allowed to be technically heavy, and should be written for a more experienced audience. But as a best practice for collaborative projects, they should still provide a Vision + Roadmap and identify the project-point person(s) (or lead(s)). + +## What makes for a good Pull Request? + +In general, we don’t have a formal structure for PRs. Our goal is to make it as efficient as possible for anyone to open a PR. But there are some good practices, which are flexible. Just keep in mind that after opening a PR there’s more to do before getting to the finish line: + +1. Reviews from other contributors and maintainers +2. Update code and, after maintainer approval, merge-in changes to the `main` branch +3. Once PR is merged, it will be released and added to the next version Release Notes with a link for anyone to look at the PR and understand it. + +Some tips and advice: + +- **Connect the dots and leave a breadcrumb**: link to related Issues, Forum discussions, etc. Help others follow the trail leading up to this PR. +- **A Helpful Description**: What does the code in the PR do and what problem does it solve? How can someone use the code? Code sample, Screenshot, Quick Video… Any or all of this is so so good. +- **Draft or Work in Progress**: You don’t have to finish the code to open a PR. Once you have a start, open it up! Most often the best way to move an Issue forward is to see the code in action. Also, often this helps identify ways forward before you spend a lot of time polishing. +- **Questions, Items for Discussion, Etc.**: Another reason to open a Draft PR is to ask questions and get direction via review. +- **Loop in a Maintainer for Feedback and Review**: ping someone with an `@`. And nudge again in a few days if there’s no reply. We appreciate it and truly don’t want the PR to get lost in the shuffle! +- **Next Steps**: Once the PR is merged, will there be a follow up step? If so, link to an Issue. How about Docs to-do or Docs to-merge? + +The best thing you can do is look through existing PRs, which will give you a feel for how things work and what you think is helpful. + +### Example PR + +If you’re looking for an example of “what makes a good PR”, look no further than this one by Kim-Adeline: + +- [Convert component generator to TS #632](https://github.com/redwoodjs/redwood/pull/632) + +Not every PR needs this much information.

This is what you install when you run `yarn create redwood-app `. It’s the thing you are building with Redwood. + +Lastly, you’ll find the template used to create a new project (when you run create redwood-app) here in GitHub: [redwoodjs/redwood/packages/create-redwood-app/template/](https://github.com/redwoodjs/redwood/tree/main/packages/create-redwood-app/template) + +We refer to this as the **CRWA Template or Project Template**. + +#### Redwood “Framework” + +The Framework is the codebase containing all the packages (and other code) that is published on NPMjs.com as `@redwoodjs/`. The Framework repository on GitHub is here: [https://github.com/redwoodjs/redwood](https://github.com/redwoodjs/redwood) + +### Development tools + +These are the tools used and recommended by the Core Team. + +**VS Code** +[Download VS Code](https://code.visualstudio.com/download) +This has quickly become the de facto editor for JavaScript and TypeScript. Additionally, we have added recommended VS Code Extensions to use when developing both the Framework and a Project. You’ll see a pop-up window asking you about installing the extensions when you open up the code. + +**GitHub Desktop** +[Download GitHub Desktop](https://desktop.github.com) +You’ll need to be comfortable using Git at the command line. But the thing we like best about GitHub Desktop is how easy it makes workflow across GitHub -- GitHub Desktop -- VS Code. You don’t have to worry about syncing permissions or finding things. You can start from a repo on GitHub.com and use Desktop to do everything from “clone and open on your computer” to returning back to the site to “open a PR on GitHub”. + +**[Mac OS] iTerm and Oh-My-Zsh** +There’s nothing wrong with Terminal (on Mac) and plain zsh or bash. (If you’re on Windows, we highly recommend using Git for Windows and Git bash.) But we enjoy using iTerm2 ([download](https://iterm2.com)) and zsh much more (combined with [Oh My Zsh](https://ohmyz.sh)). Heads up, you can get lost in the world of theming and adding plugins. We recommend keeping it simple for awhile before taking the customization deep dive +😉. + +**[Windows] Git for Windows with Git Bash or WSL(2)** +Unfortunately, there are a lot of “gotchas” when it comes to working with Javascript-based frameworks on Windows. We do our best to point out (and resolve) issues, but our priority focus is on developing a Redwood app vs contributing to the Framework. (If you’re interested, there’s a lengthy Forum conversation about this with many suggestions.) + +All that said, we highly recommend using one of the following setups to maximize your workflow: + +1. Use [Git for Windows and Git Bash](how-to/windows-development-setup.md) (included in installation) +2. Use [WSL following this setup guide on the Forums](https://community.redwoodjs.com/t/windows-subsystem-for-linux-setup/2439) + +Lastly, the new Gitpod integration is a great option and only getting better. You might just want to start using it from the beginning (see section below in “Local Development Setup”). + +**Gitpod** +We recently added an integration with [Gitpod](http://gitpod.io) that automatically creates a Framework dev workspace, complete with test project, in a browser-based VS Code environment. It’s pretty amazing and we highly recommend giving it a shot. (If you’re developing on Windows, it’s also an amazing option for you anytime you run into something that isn’t working correctly or supported.) + +But don’t skip out reading the following steps in “Local Development Setup” — Gitpod uses the same workflow and tools to initialize. If you want to develop in Gitpod, you’ll need to understand how it all works. + +But when you’re ready, learn how to use it in the section at the end [“GitPod: Browser-based Development”](#gitpod-browser-based-development). + +### Local Development Setup + +#### Step 1: Redwood Framework + +1. **Fork the [Redwood Framework](https://github.com/redwoodjs/redwood)** into a personal repo +2. Using GitHub Desktop, **open the Framework Codebase** in a VS Code workspace +3. Commands to “**start fresh**” when working on the Framework + - `yarn install`: This installs the package dependencies in /node_modules using Yarn package manager. This command is the same as just typing `yarn`. Also, if you ever switch branches and want to make sure the install dependencies are correct, you can run `yarn install --force` (shorthand `yarn -f`). + - `git clean -fxd`: _You’ll only need to do this if you’ve already been developing and want to “start over” and reset your codebase_. This command will permanently delete everything that is .gitignored, e.g. /node_modules and /dist directories with package builds. When switching between branches, this command makes sure nothing is carried over that you don’t want. (Warning: it will delete .env files in a Redwood Project. To avoid this, you can use `git clean -fxd -e .env`.) +4. **Create a new branch** from the `main` branch + First make sure you’ve pulled all changes from the remote origin (GitHub repo) into your local branch. (If you just cloned from your fork, you should be up to date.) Then create a new branch. The nomenclature used by David Price is `-description-with-hyphens`, e.g. `dsp-add-eslint-config-redwood-toml`. It's simple to use VS Code or GitHub Desktop to manage branches. You can also do this via the CLI git checkout command. + +#### Step 2: Test Project + +There are several options for creating a local Redwood Project to use during development. Anytime you are developing against a test project, there are some specific gotchas to keep in mind: + +- New projects always use the latest stable version of the Redwood packages, which will not be up to date with the latest Framework code in the `main` branch. +- To use the packages corresponding with the latest code in the Framework `main` branch, you can use the canary version published to NPM. All you need to do to install the canary versions is run `yarn rw upgrade --tag canary` in your Project +- Using a cloned project or repo? Just know there are likely breaking changes in `main` that haven’t been applied. You can examine merged PRs with the “breaking” label for more info. +- Just because you are using canary doesn’t mean you are using your local Framework branch code! Make sure you run `yarn rwfw project:sync`. And anytime you switch branches or get out of sync, you might need to start over beginning with the `git clean -fxd` command + +With those details out of the way, now is the time to choose an option below that meets your needs based on functionality and codebase version. + +**Build a Functional Test Project [Recommended]** + +1. 👉 **Use the build script to create a test project**: From the Framework root directory, run `yarn build:test-project `. This command installs a new project using the Template codebase from your current Framework branch, it then adds Tutorial features, and finally it initializes the DB (with seed data!). It should work 90% of the time and is the recommended starting place. We also use this out-of-the-box with Gitpod. + +**Other Options to create a project** + +2. **Install a fresh project using the local Framework template code:** Sometimes you need to create a project that uses the Template codebase in your local branch of the Framework, e.g. your changes include modifications to the CRWA Template and need to be tested. Running the command above is exactly the same as `yarn create redwood- app …`, only it runs the command from your local Framework package using the local Template codebase. Note: this is the same command used at the start of the `yarn build:test-project` command. + +``` +yarn babel-node packages/create-redwood-app/src/create-redwood-app.js +``` + +3. **Clone the Redwood Tutorial App repo:** This is the codebase to use when starting the Redwood Tutorial Part 2. It is updated to the latest version and has the Blog features. This is often something we use for local development. Note: be sure to upgrade to canary and look out for breaking changes coming with the next release. + +4. **Install a fresh project**: `yarn create redwood-app ` If you just need a fresh installation 1) using the latest version template codebase and 2) without any features, then just install a new Redwood project. Note: this can have the same issues regarding the need to upgrade to canary and addressing breaking changes (see Notes from items 2 and 3 above). + +> Note: All the options above currently set the language to JavaScript. If you would like to work with TypeScript, you can add the option `--typescript` to either of the commands that run the create-redwood-app installation. + +#### Step 3: Link the local Framework with the local test Project + +Once you work on the Framework code, you’ll most often want to run the code in a Redwood app for testing. However, the Redwood Project you created for testing is currently using the latest version (or canary) packages of Redwood published on NPMjs.com, e.g. [@redwoodjs/core](https://www.npmjs.com/package/@redwoodjs/core) + +So we’ll use the Redwood Framework (rwfw) command to connect our local Framework and test Projects, which allows the Project to run on the code for Packages we are currently developing. + +Run this command from the CLI in your test Project: + +``` +RWFW_PATH= yarn rwfw project:sync +``` + +For Example: + +``` +cd redwood-project +RWFW_PATH=~/redwood yarn rwfw project:sync +``` + +RWFW*PATH is the path to your local copy of the Redwood Framework. \_Once provided to rwfw, it'll remember it and you shouldn't have to provide it again unless you move it.* + +> **Heads up for Windows Devs** +> Depending on your dev setup, Windows might balk at you setting the env var RWFW_PATH at the beginning of the command like this. If so, try prepending with `cross-env`, e.g. `yarn cross-env RWFW_PATH=~/redwood yarn rwfw` ... Or you can add the env var and value directly to your shell before running the command. + +As project:sync starts up, it'll start logging to the console. In order, it: + +1. cleans and builds the framework +2. copies the framework's dependencies to your project +3. runs yarn install in your project +4. copies over the framework's packages to your project +5. waits for changes + +Step two is the only explicit change you'll see to your project. You'll see that a ton of packages have been added to your project's root package.json. + +All done? You’re ready to kill the link process with “ctrl + c”. You’ll need to confirm your root package.json no longer has the added dependencies. And, if you want to reset your test-project, you should run `yarn install --force`. + +#### Step 4: Framework Package(s) Local Testing + +Within your Framework directory, use the following tools and commands to test your code: + +1. **Build the packages**: `yarn build` + - to delete all previous build directories: yarn build:clean +2. **Syntax and Formatting**: `yarn lint` + - to fix errors or warnings: `yarn lint:fix` +3. **Run unit tests for each package**: `yarn test` +4. **Run through the Cypress E2E integration tests**: `yarn e2e` +5. **Check Yarn resolutions and package.json format**: `yarn check` + +All of these checks are included in Redwood’s GitHub PR Continuous Integration (CI) automation. However, it’s good practice to understand what they do by using them locally. The E2E tests aren’t something we use every time anymore (because it takes a while), but you should learn how to use it because it comes in handy when your code is failing tests on GitHub and you need to diagnose. + +> **Heads up for Windows Devs** +> The Cypress E2E does _not_ work on Windows. Two options are available if needed: +> +> 1. Use Gitpod (see related section for info) +> 2. When you create a PR, just ask for help from a maintainer + +#### Step 5: Open a PR 🚀 + +You’ve made it to the fun part! It’s time to use the code you’re working on to create a new PR into the Redwood Framework `main` branch. + +We use GitHub Desktop to walk through the process of: + +- Committing my changes to my development branch +- Publishing (pushing) my branch and changes to my GitHub repo fork of the Redwood Framework +- Opening a PR requesting to merge my forked-repo branch into the Redwood Framework `main` branch + +> While we use GitHub Desktop as an example, the basic process outlined above is the same whether using the command line or other clients. + +1. **Commit Files:** Using GitHub Desktop, browse to your local Redwood Framework repository and select the current branch you're working on. On the left-hand side, you'll see the files that have been modified, added, or removed. Check the boxes for the files you want to include in the PR. Below the file list, you'll see two text boxes and a "Commit to <your-branch-name>" button. Write a short commit message in the first box. If you want to add a longer description then you can do so in the second box. Click the "Commit to ..." button to commit the changes to the branch. The files are now committed under that commit message. + +2. **Push Files:** After committing, you should see an option appear with the count of local commits and a button to "Push origin." If you're ready to push those changes to the remote branch, click that button. Otherwise, you can keep working and add more commits using the process in step 1. + +3. **Create Pull Request:** Once the commit(s) have been pushed, you should see another option for "Create Pull Request." This will open a browser window to GitHub's "Open a pull request" form. Fill out the appropriate information, check the box to "Allow edits by maintainers," and submit! + +> If you are following along and are not using GitHub Desktop, after pushing your commits, you can open a pull request by visiting [github.com](https://github.com) and browsing to your fork. There should be a button at the top to submit a pull request. + +You have successfully submitted your PR! + +**Note:** Make sure you check the box that allows project maintainers to update your branch. This option is found on the "Open a pull request" form below the description textbox. Checking this option helps move a PR forward more quickly, as branches always need to be updated from `main` before we can merge. + +**When is my code “ready” to open a PR?** +Most of the action, communication, and decisions happen within a PR. A common mistake new contributors make is _waiting_ until their code is “perfect” before opening a PR. Assuming your PR has some code changes, it’s great practice to open a [Draft PR](https://github.blog/2019-02-14-introducing-draft-pull-requests/) (setting during the PR creation), which you can use to start discussion and ask questions. PRs are closed all the time without being merged, often because they are replaced by another PR resulting from decisions and discussion. It’s part of the process. More importantly, it means collaboration is happening! + +What isn’t a fun experience is spending a whole bunch of time on code that ends up not being the correct direction or is unnecessary/redundant to something that already exists. This is a part of the learning process. But it’s another reason to open a draft PR sooner than later to get confirmation and questions out of the way before investing time into refining and details. + +When in doubt, just try first and ask for help and direction! + +Refer to the [What makes for a good Pull Request?](contributing-overview.md#what-makes-for-a-good-pull-request) section in [Contributing Overview](contributing-overview.md)for general good practices when opening PR. + +### Gitpod: Browser-based Development + +[Gitpod](http://gitpod.io) has recently been integrated with Redwood to JustWork™ with any branch or PR.

In a nutshell, by default, browsers aren't allowed to access resources outside their own domain. + +## When you need to worry about CORS + +If your api and web sides are deployed to different domains, you'll have to worry about CORS. For example, if your web side is deployed to `example.com` but your api is `api.example.com`. For security reasons your browser will not allow XHR requests (like the kind that the GraphQL client makes) to a domain other than the one currently in the browser's address bar. + +This will become obvious when you point your browser to your site and see none of your GraphQL data. When you look in the web inspector you'll see a message along the lines of: + +> ⛔️ Access to fetch https://api.example.com has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. + +## Avoiding CORS + +Dealing with CORS can complicate your app and make it harder to deploy to new hosts, run in different environments, etc. Is there a way to avoid CORS altogether? + +Yes! If you can add a proxy between your web and api sides, all requests will _appear_ to be going to and from the same domain (the web side, even though behind the scenes they are forwarded somewhere else). This functionality is included automatically with hosts like [Netlify](https://docs.netlify.com/routing/redirects/rewrites-proxies/#proxy-to-another-service) or [Vercel](https://vercel.com/docs/cli#project-configuration/rewrites). With a host like [Render](https://render-web.onrender.com/docs/deploy-redwood#deployment) you can enable a proxy with a simple config option. Most providers should provide this functionality through a combination of provider-specific config and/or web server configuration. + +## GraphQL Config + +You'll need to add CORS headers to GraphQL responses. You can do this easily enough by adding the `cors` option in `api/src/functions/graphql.js` (or `graphql.ts`): + +```diff +export const handler = createGraphQLHandler({ + loggerConfig: { logger, options: {} }, + directives, + sdls, + services, ++ cors: { ++ origin: 'https://www.example.com', // <-- web side domain ++ }, + onException: () => { + db.$disconnect() + }, +}) +``` + +Note that the `origin` needs to be a complete URL including the scheme (`https`). This is the domain that requests are allowed to come _from_. In this example we assume the web side is served from `https://www.example.com`. If you have multiple servers that should be allowed to access the api, you can pass an array of them instead: + +```jsx +cors: { + origin: ['https://example.com', 'https://www.example.com'] +}, +``` + +The proper one will be included in the CORS header depending on where the response came from. + +## Authentication Config + +The following config only applies if you're using [dbAuth](authentication.md#self-hosted-auth-installation-and-setup), which is Redwood's own cookie-based auth system. + +You'll need to configure several things: + +- Add CORS config for GraphQL +- Add CORS config for the auth function +- Cookie config for the auth function +- Allow sending of credentials in GraphQL XHR requests +- Allow sending of credentials in auth function requests + +Here's how you configure each of these: + +### GraphQL CORS Config + +You'll need to add CORS headers to GraphQL responses, and let the browser know to send up cookies with any requests. Add the `cors` option in `api/src/functions/graphql.js` (or `graphql.ts`) with an additional `credentials` property: + +```diff +export const handler = createGraphQLHandler({ + loggerConfig: { logger, options: {} }, + directives, + sdls, + services, ++ cors: { ++ origin: 'https://www.example.com', // <-- web side domain ++ credentials: true, ++ }, + onException: () => { + db.$disconnect() + }, +}) +``` + +`origin` is the domain(s) that requests come _from_ (the web side). + +### Auth CORS Config + +Similar to the `cors` options being sent to GraphQL, you can set similar options in `api/src/functions/auth.js` (or `auth.ts`): + +```diff +const authHandler = new DbAuthHandler(event, context, { + db: db, + authModelAccessor: 'user', + authFields: { + id: 'id', + username: 'email', + hashedPassword: 'hashedPassword', + salt: 'salt', + resetToken: 'resetToken', + resetTokenExpiresAt: 'resetTokenExpiresAt', + }, ++ cors: { ++ origin: 'https://www.example.com', // <-- web side domain ++ credentials: true, ++ }, + cookie: { + HttpOnly: true, + Path: '/', + SameSite: 'Strict', + Secure: true, + }, + forgotPassword: forgotPasswordOptions, + login: loginOptions, + resetPassword: resetPasswordOptions, + signup: signupOptions, +}) +``` + +Just like the GraphQL config, `origin` is the domain(s) that requests come _from_ (the web side). + +### Cookie Config + +In order to be able accept cookies from another domain we'll need to make a change to the `SameSite` option in `api/src/functions/auth.js` and set it to `None`: + +```jsx {4} + cookie: { + HttpOnly: true, + Path: '/', + SameSite: 'None', + Secure: true, + }, +``` + +### GraphQL XHR Credentials + +Next we need to tell the GraphQL client to include credentials (the dbAuth cookie) in any requests. This config goes in `web/src/App.{ts,js}`: + +```jsx {7-12} +import { AuthProvider, useAuth } from 'src/auth' + +const App = () => ( + + + + + + + + + +) +``` + +### Auth XHR Credentials + +Finally, we need to tell dbAuth to include credentials in its own XHR requests. We'll do this within `web/src/auth.{ts,js}` when creating the `AuthProvider`: + +```jsx {3-5} +import { createDbAuthClient, createAuth } from '@redwoodjs/auth-dbauth-web' + +const dbAuthClient = createDbAuthClient({ + fetchConfig: { credentials: 'include' }, +}) + +export const { AuthProvider, useAuth } = createAuth(dbAuthClient) +``` + +## Testing CORS Locally + +If you've made the configuration changes above, `localhost` testing should continue working as normal. But, if you want to make sure your CORS config works without deploying to the internet somewhere, you'll need to do some extra work. + +### Serving Sides to the Internet + +First, you need to get the web and api sides to be serving from different hosts. A tool like [ngrok](https://ngrok.com/) or [localhost.run](https://localhost.run/) allows you to serve your local development environment over a real domain to the rest of the internet (on both `http` and `https`). + +You'll need to start two tunnels, one for the web side (this example assumes ngrok): + +```bash +> ngrok http 8910 + +Session Status online +Account Your Name (Plan: Pro) +Version 2.3.40 +Region United States (us) +Web Interface http://127.0.0.1:4040 +Forwarding http://3c9913de0c00.ngrok.io -> http://localhost:8910 +Forwarding https://3c9913de0c00.ngrok.io -> http://localhost:8910 +``` + +And another for the api side: + +```bash +> ngrok http 8911 + +Session Status online +Account Your Name (Plan: Pro) +Version 2.3.40 +Region United States (us) +Web Interface http://127.0.0.1:4040 +Forwarding http://fb6d701c44b5.ngrok.io -> http://localhost:8911 +Forwarding https://fb6d701c44b5.ngrok.io -> http://localhost:8911 +``` + +Note the two different domains. Copy the `https` domain from the api side because we'll need it in a moment. Even if the Redwood dev server isn't running you can leave these tunnels running, and when the dev server _does_ start, they'll just start on those domains again. + +### `redwood.toml` Config + +You'll need to make two changes here: + +1. Bind the server to all network interfaces +2. Point the web side to the api's domain + +Normally the dev server only binds to `127.0.0.1` (home sweet home) which means you can only access it from your local machine using `localhost` or `127.0.0.1`. To tell it to bind to all network interfaces, and to be available to the outside world, add this `host` option: + +```toml {4} +[web] + title = "Redwood App" + port = 8910 + host = '0.0.0.0' + apiUrl = '/.redwood/functions' + includeEnvironmentVariables = [] +[api] + port = 8911 +[browser] + open = true +``` + +We'll also need to tell the web side where the api side lives. Update the `apiUrl` to whatever domain your api side is running on (remember the domain you copied from from ngrok): + +```toml {5} +[web] + title = "Redwood App" + port = 8910 + host = '0.0.0.0' + apiUrl = 'https://fb6d701c44b5.ngrok.io' + includeEnvironmentVariables = [] +[api] + port = 8911 +[browser] + open = true +``` + +Where you get this domain from will depend on how you expose your app to the outside world (this example assumes ngrok). + +### Starting the Dev Server + +You'll need to apply an option when starting the dev server to tell it to accept requests from any host, not just `localhost`: + +```bash +rw > yarn dev --fwd="--allowed-hosts all" +``` + +### Wrapping Up + +Now you should be able to open the web side's domain in a browser and use your site as usual. Test that GraphQL requests work, as well as authentication if you are using dbAuth. diff --git a/docs/versioned_docs/version-8.2/create-redwood-app.md b/docs/versioned_docs/version-8.2/create-redwood-app.md new file mode 100644 index 000000000000..1d4fe329bde7 --- /dev/null +++ b/docs/versioned_docs/version-8.2/create-redwood-app.md @@ -0,0 +1,106 @@ +--- +slug: create-redwood-app +description: Instructions and usage examples for Create Redwood App +--- + +# Create Redwood App + +To get up and running with Redwood, you can use Create Redwood App: + +```terminal +yarn create redwood-app +``` + +## Set up for success + +Redwood requires that you're running Node version 20 or higher. + +If you're running Node version 21.0.0 or higher, you can still use Create Redwood App, but it may make your project incompatible with some deploy targets, such as AWS Lambdas. + +To see what version of Node you're running, you can run the following command in your terminal: + +```terminal +node -v +``` + +If you need to update your version of Node or run multiple versions of Node, we recommend installing nvm and have [documentation about how to get up and running.](./how-to/using-nvm) + +You also need to have yarn version 1.22.21 or higher installed.

See the README for `node-type` for more info: https://github.com/nodejs/node-gyp#installation + +### Configuration + +Before your first deploy you'll need to add some configuration. + +#### ecosystem.config.js + +By default, baremetal assumes you want to run the `yarn rw serve` command, which provides both the web and api sides. The web side will be available on port 8910 unless you update your `redwood.toml` file to make it available on another port. The default generated `ecosystem.config.js` will contain this config only, within a service called "serve": + +```jsx title="ecosystem.config.js" +module.exports = { + apps: [ + { + name: 'serve', + cwd: 'current', + script: 'node_modules/.bin/rw', + args: 'serve', + instances: 'max', + exec_mode: 'cluster', + wait_ready: true, + listen_timeout: 10000, + }, + ], +} +``` + +If you follow our recommended config [below](#redwood-serves-api-nginx-serves-web-side), you could update this to only serve the api side, because the web side will be handled by [nginx](https://www.nginx.com/). That could look like: + +```jsx title="ecosystem.config.js" +module.exports = { + apps: [ + { + name: 'api', + cwd: 'current', + script: 'node_modules/.bin/rw', + args: 'serve api', + instances: 'max', + exec_mode: 'cluster', + wait_ready: true, + listen_timeout: 10000, + }, + ], +} +``` + +#### deploy.toml + +This file contains your server configuration: which servers to connect to and which commands to run on them. + +```toml title="deploy.toml" +[[production.servers]] +host = "server.com" +username = "user" +agentForward = true +sides = ["api","web"] +packageManagerCommand = "yarn" +monitorCommand = "pm2" +path = "/var/www/app" +processNames = ["serve"] +repo = "git@github.com:myorg/myapp.git" +branch = "main" +keepReleases = 5 +``` + +This lists a single server, in the `production` environment, providing the hostname and connection details (`username` and `agentForward`), which `sides` are hosted on this server (by default it's both web and api sides), the `path` to the app code and then which PM2 service names should be (re)started on this server. + +#### Config Options + +- `host` - hostname to the server +- `port` - [optional] ssh port for server connection, defaults to 22 +- `username` - the user to login as +- `password` - [optional] if you are using password authentication, include that here +- `privateKey` - [optional] if you connect with a private key, include the content of the key here, as a buffer: `privateKey: Buffer.from('...')`. Use this _or_ `privateKeyPath`, not both. +- `privateKeyPath` - [optional] if you connect with a private key, include the path to the key here: `privateKeyPath: path.join('path','to','key.pem')` Use this _or_ `privateKey`, not both. +- `passphrase` - [optional] if your private key contains a passphrase, enter it here +- `agentForward` - [optional] if you have [agent forwarding](https://docs.github.com/en/developers/overview/using-ssh-agent-forwarding) enabled, set this to `true` and your own credentials will be used for further SSH connections from the server (like when connecting to GitHub) +- `sides` - An array of sides that will be built on this server +- `packageManagerCommand` - The package manager bin to call, defaults to `yarn` but could be updated to be prefixed with another command first, for example: `doppler run -- yarn` +- `monitorCommand` - The monitor bin to call, defaults to `pm2` but could be updated to be prefixed with another command first, for example: `doppler run -- pm2` +- `path` - The absolute path to the root of the application on the server +- `migrate` - [optional] Whether or not to run migration processes on this server, defaults to `true` +- `processNames` - An array of service names from `ecosystem.config.js` which will be (re)started on a successful deploy +- `repo` - The path to the git repo to clone +- `branch` - [optional] The branch to deploy (defaults to `main`) +- `keepReleases` - [optional] The number of previous releases to keep on the server, including the one currently being served (defaults to 5) + +The easiest connection method is generally to include your own public key in the server's `~/.ssh/authorized_keys` mannually or by running `ssh-copy-id user@server.com` from your local machine, [enable agent forwarding](https://docs.github.com/en/developers/overview/using-ssh-agent-forwarding), and then set `agentForward = true` in `deploy.toml`. This will allow you to use your own credentials when pulling code from GitHub (required for private repos). Otherwise you can create a [deploy key](https://docs.github.com/en/developers/overview/managing-deploy-keys) and keep it on the server. + +#### Using Environment Variables in `deploy.toml` + +Similarly to `redwood.toml`, `deploy.toml` supports interpolation of environment variables. For more details on how to use the environment variable interpolation see [Using Environment Variables in redwood.toml](/docs/app-configuration-redwood-toml#using-environment-variables-in-redwoodtoml) + +#### Multiple Servers + +If you start horizontally scaling your application you may find it necessary to have the web and api sides served from different servers. The configuration files can accommodate this: + +```toml title="deploy.toml" +[[production.servers]] +host = "api.server.com" +username = "user" +agentForward = true +sides = ["api"] +path = "/var/www/app" +processNames = ["api"] + +[[production.servers]] +host = "web.server.com" +username = "user" +agentForward = true +sides = ["web"] +path = "/var/www/app" +migrate = false +processNames = ["web"] +``` + +```jsx title="ecosystem.config.js" +module.exports = { + apps: [ + { + name: 'api', + cwd: 'current', + script: 'node_modules/.bin/rw', + args: 'serve api', + instances: 'max', + exec_mode: 'cluster', + wait_ready: true, + listen_timeout: 10000, + }, + { + name: 'web', + cwd: 'current', + script: 'node_modules/.bin/rw', + args: 'serve web', + instances: 'max', + exec_mode: 'cluster', + wait_ready: true, + listen_timeout: 10000, + }, + ], +} +``` + +Note the inclusion of `migrate = false` so that migrations are not run again on the web server (they only need to run once and it makes sense to keep them with the api side). + +You can add as many `[[servers]]` blocks as you need. + +#### Multiple Environments + +You can deploy to multiple environments from a single `deploy.toml` by including servers grouped by environment name: + +```toml title="deploy.toml" +[[production.servers]] +host = "prod.server.com" +username = "user" +agentForward = true +sides = ["api", "web"] +path = "/var/www/app" +processNames = ["serve"] + +[[staging.servers]] +host = "staging.server.com" +username = "user" +agentForward = true +sides = ["api", "web"] +path = "/var/www/app" +processNames = ["serve", "stage-logging"] +``` + +At deploy time, include the environment in the command: + +```bash +yarn rw deploy baremetal staging +``` + +Note that the codebase shares a single `ecosystem.config.js` file. If you need a different set of services running in different environments you'll need to simply give them a unique name and reference them in the `processNames` option of `deploy.toml` (see the additional `stage-logging` process in the above example). + +## Server Setup + +You will need to create the directory in which your app code will live. This path will be the `path` var in `deploy.toml`. Make sure the username you will connect as in `deploy.toml` has permission to read/write/execute files in this directory. For example, if your `/var` dir is owned by `root`, but you're going to deploy with a user named `deploy`: + +```bash +sudo mkdir -p /var/www/myapp +sudo chown deploy:deploy /var/www/myapp +``` + +You'll want to create an `.env` file in this directory containing any environment variables that are needed by your app (like `DATABASE_URL` at a minimum). This will be symlinked to each release directory so that it's available as the app expects (in the root directory of the codebase). + +:::warning SSH and Non-interactive Sessions + +The deployment process uses a '[non-interactive](https://tldp.org/LDP/abs/html/intandnonint.html)' SSH session to run commands on the remote server. A non-interactive session will often load a minimal amount of settings for better compatibility and speed. In some versions of Linux `.bashrc` by default does not load (by design) from a non-interactive session. This can lead to `yarn` (or other commands) not being found by the deployment script, even though they are in your path, because additional ENV vars are set in `~/.bashrc` which provide things like NPM paths and setup. + +A quick fix on some distros is to edit the deployment user's `~/.bashrc` file and comment out the lines that _stop_ non-interactive processing. + +```diff title="~/.bashrc" +# If not running interactively, don't do anything +- case $- in +- *i*) ;; +- *) return;; +- esac + +# If not running interactively, don't do anything ++ # case $- in ++ # *i*) ;; ++ # *) return;; ++ # esac +``` + +This may also be a one-liner like: + +```diff title="~/.bashrc" +- [ -z "$PS1" ] && return ++ # [ -z "$PS1" ] && return +``` + +There are techniques for getting `node`, `npm` and `yarn` to be available without loading everything in `.bashrc`. See [this comment](https://github.com/nvm-sh/nvm/issues/1290#issuecomment-427557733) for some ideas. + +::: + +## First Deploy + +Back on your development machine, enter your details in `deploy.toml`, commit it and push it up, and then try a first deploy: + +```bash +yarn rw deploy baremetal production --first-run +``` + +If there are any issues the deploy should stop and you'll see the error message printed to the console. + +If it worked, hooray! You're deployed to BAREMETAL. If not, read on... + +### Troubleshooting + +On the server you should see a new directory inside the `path` you defined in `deploy.toml`. It should be a timestamp of the deploy, like: + +```bash +drwxrwxr-x 7 ubuntu ubuntu 4096 Apr 22 23:00 ./ +drwxr-xr-x 7 ubuntu ubuntu 4096 Apr 22 22:46 ../ +-rw-rw-r-- 1 ubuntu ubuntu 1167 Apr 22 20:49 .env +drwxrwxr-x 10 ubuntu ubuntu 4096 Apr 22 21:43 20220422214218/ +``` + +You may or may not also have a `current` symlink in the app directory pointing to that timestamp directory (it depends how far the deploy script got before it failed as to whether you'll have the symlink or not). + +`cd` into that timestamped directory and check that you have a `.env` symlink pointing back to the app directory's `.env` file. + +Next, try performing all of the steps yourself that would happen during a deploy: + +``` +yarn install +yarn rw prisma migrate deploy +yarn rw prisma generate +yarn rw dataMigrate up +yarn rw build +ln -nsf "$(pwd)" ../current +``` + +If they worked for you, the deploy process should have no problem as it runs the same commands (after all, it connects via SSH and runs the same commands you just did!) + +Next we can check that the site is being served correctly. Run `yarn rw serve` and make sure your processes start and are accessible (by default on port 8910): + +```bash +curl http://localhost:8910 +# or +wget http://localhost:8910 +``` + +If you don't see the content of your `web/src/index.html` file then something isn't working. You'll need to fix those issues before you can deploy. Verify the api side is responding: + +```bash +curl http://localhost:8910/.redwood/functions/graphql?query={redwood{version}} +# or +wget http://localhost:8910/.redwood/functions/graphql?query={redwood{version}} +``` + +You should see something like: + +```json +{ + "data": { + "redwood": { + "version": "1.0.0" + } + } +} +``` + +If so then your API side is up and running! The only thing left to test is that the api side has access to the database. This call would be pretty specific to your app, but assuming you have port 8910 open to the world you could simply open a browser to click around to find a page that makes a database request. + +Was the problem with starting your PM2 process? That will be harder to debug here in this doc, but visit us in the [forums](https://community.redwoodjs.com) or [Discord](https://discord.gg/redwoodjs) and we'll try to help! + +:::note My pm2 processes are running but your app has errors, how do I see them? + +If your processes are up and running in pm2 you can monitor their log output. Run `pm2 monit` and get a nice graphical interface for watching the logs on your processes. Press the up/down arrows to move through the processes and left/right to switch panes. + +![pm2 monit screenshot](https://user-images.githubusercontent.com/300/213776175-2f78d9d4-7e6e-4d69-81b2-a648cc37b6ea.png) + +Sometimes the log messages are too long to read in the pane at the right. In that case you can watch them live by "tailing" them right in the terminal. pm2 logs are written to `~/.pm2/logs` and are named after the process name and id, and whether they are standard output or error messages. Here's an example directory listing: + +``` +ubuntu@ip-123-45-67-89:~/.pm2/logs$ ll +total 116 +drwxrwxr-x 2 ubuntu ubuntu 4096 Jan 20 17:58 ./ +drwxrwxr-x 5 ubuntu ubuntu 4096 Jan 20 17:40 ../ +-rw-rw-r-- 1 ubuntu ubuntu 0 Jan 20 17:58 api-error-0.log +-rw-rw-r-- 1 ubuntu ubuntu 0 Jan 20 17:58 api-error-1.log +-rw-rw-r-- 1 ubuntu ubuntu 27788 Jan 20 18:11 api-out-0.log +-rw-rw-r-- 1 ubuntu ubuntu 21884 Jan 20 18:11 api-out-1.log +``` + +To watch a log live, run: + +```terminal +tail -f ~/.pm2/logs/api-out-0.log +``` + +Note that if you have more than one process running, like we do here, requesting a page on the website will send the request to one of available processes randomly, so you may not see your request show up unless you refresh a few times. Or you can connect to two separate SSH sessions and tail both of the log files at the same time. + +::: + +## Starting Processes on Server Restart + +The `pm2` service requires some system "hooks" to be installed so it can boot up using your system's service manager. Otherwise, your PM2 services will need to be manually started again on a server restart. These steps only need to be run the first time you install PM2. + +SSH into your server and then run: + +```bash +pm2 startup +``` + +You will see some output similar to the output below. We care about the output after "copy/paste the following command:" You'll need to do just that: copy the command starting with `sudo` and then paste and execute it. _Note_ this command uses `sudo` so you'll need the root password to the machine in order for it to complete successfully. + +:::warning + +The below text is _example_ output, yours will be different, don't copy and paste ours! + +::: + +```bash +$ pm2 startup +[PM2] Init System found: systemd +[PM2] To setup the Startup Script, copy/paste the following command: +// highlight-next-line +sudo env PATH=$PATH:/home/ubuntu/.nvm/versions/node/v16.13.2/bin /home/ubuntu/.nvm/versions/node/v16.13.2/lib/node_modules/pm2/bin/pm2 startup systemd -u ubuntu --hp /home/ubuntu +``` + +In this example, you would copy `sudo env PATH=$PATH:/home/ubuntu/.nvm/versions/node/v16.13.2/bin /home/ubuntu/.nvm/versions/node/v16.13.2/lib/node_modules/pm2/bin/pm2 startup systemd -u ubuntu --hp /home/ubuntu` and run it. You should get a bunch of output along with `[PM2] [v] Command successfully executed.` near the end. Now if your server restarts for whatever reason, your PM2 processes will be restarted once the server is back up. + +## Customizing the Deploy + +There are several ways you can customize the deploys steps, whether that's skipping steps completely, or inserting your own commands before or after the default ones. + +### Skipping Steps + +If you want to speed things up you can skip one or more steps during the deploy. For example, if you have no database migrations, you can skip them completely and save some time: + +```bash +yarn rw deploy baremetal production --no-migrate +``` + +Run `yarn rw deploy baremetal --help` for the full list of flags. You can set them as `--migrate=false` or use the `--no-migrate` variant. + +### Inserting Custom Commands + +Baremetal supports running your own custom commands before or after the regular deploy commands. You can run commands **before** and/or **after** the built-in commands. Your custom commands are defined in the `deploy.toml` config file. The existing commands that you can hook into are: + +1. `update` - cloning the codebase +2. `symlinkEnv` - symlink the new deploy's `.env` to shared one in the app dir +3. `install` - `yarn install` +4. `migrate` - database migrations +5. `build` - `yarn build` (your custom before/after command is run for each side being built) +6. `symlinkCurrent` - symlink the new deploy dir to `current` in the app dir +7. `restart` - (re)starting any pm2 processes (your custom command will run before/after each process is restarted) +8. `cleanup` - cleaning up any old releases + +You can define your before/after commands in three different places: + +- Globally - runs for any environment +- Environment specific - runs for only a single environment +- Server specific - runs for only a single server in a single environment + +:::warning + +Custom commands are run in the new **deploy** directory, not the root of your application directory. During a deploy the `current` symlink will point to the previous directory while your code is executed in the new one, before the `current` symlink location is updated. + +```bash +drwxrwxr-x 5 ubuntu ubuntu 4096 May 10 18:20 ./ +drwxr-xr-x 7 ubuntu ubuntu 4096 Apr 27 17:43 ../ +drwxrwxr-x 2 ubuntu ubuntu 4096 May 9 22:59 20220503211428/ +drwxrwxr-x 2 ubuntu ubuntu 4096 May 9 22:59 20220503211429/ +drwxrwxr-x 10 ubuntu ubuntu 4096 May 10 18:18 20220510181730/ commands are run in here < -- +lrwxrwxrwx 1 ubuntu ubuntu 14 May 10 18:19 current - > 20220503211429/ +-rw-rw-r-- 1 ubuntu ubuntu 1167 Apr 22 20:49 .env +``` + +::: + +#### Syntax + +Global events are defined in a `[before]` and/or `[after]` block in your `deploy.toml` file: + +```toml +[before] +install = "touch install.lock" + +[after] +install = "rm install.lock" + +[[production.servers]] +host = 'server.com' +# ... +``` + +Environment specific commands are defined in a `[[environment.before]]` and `[[environment.after]]` block: + +```toml +[production.before] +install = "touch prod-install.lock" + +[production.after] +install = "rm prod-install.lock" + +[production.servers] +host = 'server.com' +# ... +``` + +Server specific commands are defined with a `before.command` and `after.command` key directly in your server config: + +```toml +[[production.servers]] +host = 'server.com' +# ... +before.install = 'touch server-install.lock' +after.install = 'rm server-install.lock' +``` + +You can define commands as a string, or an array of strings if you want to run multiple commands: + +```toml +[before] +install = ["echo 'started at $(date)' > install.lock", "cp -R . ../backup"] + +[[production.servers]] +host = 'server.com' +# ... +``` + +You can include commands in any/all of the three configurations (global, env and server) and they will all be stacked up and run in that order: `global -> environment -> server`. For example: + +```toml +[[production.servers]] +host = 'server.com' +# ... +before.install = 'touch server-install.lock' + +[production.before] +install = ['touch prod-install1.lock', 'touch prod-install2.lock'] + +[before] +install = 'touch install.lock' +``` + +Would result in the commands running in this order, all before running `yarn install`: + +1. `touch install.lock` +2. `touch prod-install1.lock` +3. `touch prod-install2.lock` +4. `touch server-install.lock` + +## Rollback + +If you deploy and find something has gone horribly wrong, you can rollback your deploy to the previous release: + +```bash +yarn rw deploy baremetal production --rollback +``` + +You can even rollback multiple deploys, up to the total number you still have denoted with the `keepReleases` option: + +```bash +yarn rw deploy baremetal production --rollback 3 +``` + +Note that this will _not_ rollback your database—if you had a release that changed the database, that updated database will still be in effect, but with the previous version of the web and api sides. Trying to undo database migrations is a very difficult proposition and isn't even possible in many cases. + +Make sure to thoroughly test releases that change the database before doing it for real! + +## Maintenance Page + +If you find that you have a particular complex deploy, one that may involve incompatible database changes with the current codebase, or want to make sure that database changes don't occur while in the middle of a deploy, you can put up a maintenance page: + +```bash +yarn rw deploy baremetal production --maintenance up +``` + +It does this by replacing `web/dist/200.html` with `web/src/maintenance.html`. This means any new web requests, at any URL, will show the maintenance page. This process also stops any services listed in the `processNames` option of `deploy.toml`—this is important for the api server as it will otherwise keep serving requests to users currently running the app, even though no _new_ users can get the Javascript packages required to start a new session in their browser. + +You can remove the maintenance page with: + +```bash +yarn rw deploy baremetal production --maintenance down +``` + +Note that the maintenance page will automatically come down as the result of a new deploy as it checks out a new copy of the codebase (with a brand new copy of `web/dist/200.html` and will automatically restart services (bring them all back online). + +## Monitoring + +PM2 has a nice terminal-based dashboard for monitoring your services: + +```bash +pm2 monit +``` + +![pm2 dashboard](https://user-images.githubusercontent.com/300/164799386-84442fa3-8e68-4cc6-9e64-928b8e32731a.png) + +And even a web-based UI with paid upgrades if you need to give normies access to your monitoring data: + +![pm2 web dashboard](https://user-images.githubusercontent.com/300/164799541-6fe321fa-4d7c-44f7-93c6-3c202638da4f.png) + +## Example Server Configurations + +The default configuration, which requires the least amount of manual configuration, is to serve both the web and api sides, with the web side being bound to port 8910. This isn't really feasible for a general web app which should be available on port 80 (for HTTP) and/or port 443 (for HTTPS). Here are some custom configs to help. + +### Redwood Serves Web and Api Sides, Bind to Port 80 + +This is almost as easy as the default configuration, you just need to tell Redwood to bind to port 80. However, most \*nix distributions will not allow a process to bind to ports lower than 1024 without root/sudo permissions. There is a command you can run to allow access to a specific binary (`node` in this case) to bind to one of those ports anyway. + +#### Tell Redwood to Bind to Port 80 + +Update the `[web]` port: + +```diff title="redwood.toml" +[web] + title = "My Application" + apiUrl = "/.netlify/functions" ++ port = 80 +[api] + port = 8911 +[browser] + open = true +``` + +#### Allow Node to Bind to Port 80 + +Use the [setcap](https://man7.org/linux/man-pages/man7/capabilities.7.html) utility to provide access to lower ports by a given process: + +```bash +sudo setcap CAP_NET_BIND_SERVICE=+eip $(which node) +``` + +Now restart your service and it should be available on port 80: + +```bash +pm2 restart serve +``` + +This should get your site available on port 80 (for HTTP), but you really want it available on port 443 (for HTTPS). That won't be easy if you continue to use Redwood's internal web server. See the next recipe for a solution. + +### Redwood Serves Api, Nginx Serves Web Side + +[nginx](https://www.nginx.com/) is a very robust, dedicated web server that can do a better job of serving our static web-side files than Redwood's own built-in web server (Fastify) which isn't really configured in Redwood for a high traffic, production website. + +If nginx will be serving our web side, what about api-side? Redwood's internal API server will be running, but on the default port of 8911. But browsers are going to want to connect on port 80 (HTTP) or 443 (HTTPS). nginx takes care of this as well: it will [proxy](https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/) (forward) any requests to a path of your choosing (like the default of `/.redwood/functions`) to port 8911 behind the scenes, then return the response to the browser. + +This doc isn't going to go through installing and getting nginx running, there are plenty of resources for that available.

You can find more information by searching the [GitHub Issues](https://github.com/redwoodjs/redwood/issues) and [Forums](https://community.redwoodjs.com). + +## General Deployment Setup + +Deploying Redwood requires setup for the following four categories. + +### 1. Host Specific Configuration + +Each hosting provider has different requirements for how (and where) the deployment is configured. Sometimes you'll need to add code to your repository, configure settings in a dashboard, or both. You'll need to read the provider specific documentation. + +The most important Redwood configuration is to set the `apiUrl` in your `redwood.toml` This sets the API path for your serverless functions specific to your hosting provider. + +### 2. Build Command + +The build command is used to prepare the Web and API for deployment. Additionally, other actions can be run during build such as database migrations. The Redwood build command must specify one of the supported hosting providers (aka `target`): + +```shell +yarn rw deploy +``` + +For example: + +```shell +# Build command for Netlify deploy target +yarn rw deploy netlify +``` + +```shell +# Build command for Vercel deploy target +yarn rw deploy vercel +``` + +```shell +# Build command for AWS Lambdas using the https://serverless.com framework +yarn rw deploy serverless --side api +``` + +```shell +# Build command for Edgio deploy target +yarn rw deploy edgio +``` + +```shell +# Build command for baremetal deploy target +yarn rw deploy baremetal [--first-run] +``` + +### 3. Prisma and Database + +Redwood uses Prisma for managing database access and migrations. The settings in `api/prisma/schema.prisma` must include the correct deployment database, e.g. postgresql, and the database connection string. + +To use PostgreSQL in production, include this in your `schema.prisma`: + +```jsx +datasource db { + provider = "postgresql" + url = env("DATABASE_URL") +} +``` + +The `url` setting above accesses the database connection string via an environment variable, `DATABASE_URL`. Using env vars is the recommended method for both ease of development process as well as security best practices. + +Whenever you make changes to your `schema.prisma`, you must run the following command: + +```shell +yarn rw prisma migrate dev # creates and applies a new Prisma DB migration +``` + +> Note: when setting your production DATABASE_URL env var, be sure to also set any connection-pooling or sslmode parameters. For example, if using Supabase Postgres with pooling, then you would use a connection string similar to `postgresql://postgres:mydb.supabase.co:6432/postgres?sslmode=require&pgbouncer=true` that uses a specific 6432 port, informs Prisma to consider pgBouncer, and also to use SSL. See: [Connection Pooling](connection-pooling.md) for more info. + +### 4. Environment Variables + +Any environment variables used locally, e.g. in your `env.defaults` or `.env`, must also be added to your hosting provider settings. (See documentation specific to your provider.) + +Additionally, if your application uses env vars on the Web Side, you must configure Redwood's build process to make them available in production.

Any bill you receive is from your hosting provider (although many offer a generous free tier). You can optionally use the [Serverless Dashboard](https://www.serverless.com/dashboard/) to monitor your deploys and setup CI/CD to automatically deploy when pushing to your repo of choice. If you don't setup CI/CD you actually deploy from your development machine (or another designated machine you've setup to do the deployment). + +Currently we default to deploying to AWS.

They will override any same-named vars in `.env`. Make sure neither of these files is checked into your code repository! + +If you're setting up CI/CD and deploying from the Serverless Dashboard, you'll need to copy your required ENV vars up to your app on Serverless and then tell it where to get them from. In `api/serverless.yml` and `web/serverless.yml` look for the `provider > environment` section. You'll need to list any ENV vars here, using the `${param:VAR_NAME}` syntax, which means to get them from the Serverless Dashboard "parameters" (which is what they call environment variables, for some strange reason). + +There are even more places you can get environment variables from, check out Serverless's [Variables documentation](https://www.serverless.com/framework/docs/providers/aws/guide/variables) for more. + +## Serverless Dashboard + +> **Note:** +> Serverless Dashboard CI/CD does not support projects structured like Redwood, although they're working on it. For CD, you'll need to use something like GitHub Actions. +> +> It can still be worthwhile to integrate your project with Serverless Dashboard — you'll have features like deploy logs and monitoring, analytics, secret management, and AWS account integration. You can also [authenticate into your Serverless account within a CI context](https://www.serverless.com/framework/docs/guides/cicd/running-in-your-own-cicd). Just remember that if you do use the Dashboard to manage secrets, you'll need to use the `${param:VAR_NAME}` syntax. + +To integrate your site into the Serverless Dashboard, there are two ways: + +1. Run `yarn serverless login` and a browser _should_ open asking you to allow permission. However, in our experience, this command will fail nearly 50% of the time complaining about an invalid URL. If it _does_ work you can then run `yarn serverless` in both the `api` and `web` directories to link to them an existing app in the Dashboard, or you'll be prompted to create a new one. Future deploys will now be monitored on the Dashboard. +2. You can manually add the `org` and `app` lines in `api/serverless.yml` and `web/serverless.yml`. You'll see example ones commented out near the top of the file. + +## Environments Besides Production + +By default we assume you want to deploy to a production environment, but Serverless lets you deploy anywhere.

For example, if you're on the Hobby plan, there are some storage and write limits that you can mitigate by turning the Prisma and data migration steps off during deploy and only enabling them on a case-by-case basis when needed: + +``` +yarn rw deploy vercel --prisma=false --data-migrate=false +``` + +::: + +### Vercel Initial Setup and Configuration + +Either [login](https://vercel.com/login) to your Vercel account and select "Import Project" or use the Vercel [quick start](https://vercel.com/#get-started). + +Then select the "Continue" button within the "From Git Repository" section: + + +Next, select the provider where your repo is hosted: GitHub, GitLab, or Bitbucket. You'll be asked to login and then provider the URL of the repository, e.g. for a GitHub repo `https://github.com/your-account/your-project.git`. Select "Continue". + +You'll then need to provide permissions for Vercel to access the repo on your hosting provider. + +### Import and Deploy your Project + +Vercel will recognize your repo as a Redwood project and take care of most configuration heavy lifting. You should see the following options and, most importantly, the "Framework Preset" showing RedwoodJS. + + + +Leave the **Build and Output Settings** at the default settings (unless you know what you're doing and have very specific needs). + +In the "Environment Variables" dropdown, add `DATABASE_URL` and your app's database connection string as the value. (Or skip if not applicable.) + +> When configuring a database, you'll want to append `?connection_limit=1` to the URI. This is [recommended by Prisma](https://www.prisma.io/docs/reference/tools-and-interfaces/prisma-client/deployment#recommended-connection-limit) when working with relational databases in a Serverless context. For production apps, you should setup [connection pooling](https://redwoodjs.com/docs/connection-pooling). + +For example, a postgres connection string should look like `postgres://:@/?connection_limit=1` + +Finally, click the "Deploy" button. You'll hopefully see a build log without errors (warnings are fine) and end up on a screen that looks like this: + + + +Go ahead, click that "Visit" button. You’ve earned it 🎉 + +## Vercel Dashboard Settings + +From the Vercel Dashboard you can access the full settings and information for your Redwood App. The default settings seem to work just fine for most Redwood projects. Do take a look around, but be sure check out the [docs as well](https://vercel.com/docs). + +From now on, each time you push code to your git repo, Vercel will automatically trigger a deploy of the new code. You can also manually redeploy if you select "Deployments", then the specific deployment from the list, and finally the "Redeploy" option from the vertical dots menu next to "Visit". + +## Configuration + +You can use `vercel.json` to configure and override the default behavior of Vercel from within your project. For [`functions`](#functions), you should configure in code directly and not in `vercel.json`. + +### Project + +The [`vercel.json` configuration file](https://vercel.com/docs/projects/project-configuration#configuring-projects-with-vercel.json) lets you configure, and override the default behavior of Vercel from within your project such as rewrites or headers. + +### Functions + +By default, API requests in Vercel have a timeout limit of 15 seconds, but can be configured to be up to 90 seconds. Pro and other plans allow for longer [duration](https://vercel.com/docs/functions/runtimes#max-duration) and larger [memory-size limits](https://vercel.com/docs/functions/runtimes#memory-size-limits). + +To change the `maxDuration` or `memory` per function, export a `config` with the settings you want applied in your function. For example: + +```ts +import type { APIGatewayEvent, Context } from 'aws-lambda' + +import { logger } from 'src/lib/logger' + +export const config = { + maxDuration: 30, + memory: 512, +} + +export const handler = async (event: APIGatewayEvent, _context: Context) => { + logger.info(`${event.httpMethod} ${event.path}: vercel function`) + + return { + statusCode: 200, + headers: { + 'Content-Type': 'application/json', + }, + body: JSON.stringify({ + data: 'vercel function', + }), + } +} +``` + +:::tip important +Since Redwood has it's own handling of the api directory, the Vercel flavored api directory is disabled. Therefore you don't use the "functions" config in `vercel.json` with Redwood. + +Also, be sure to use Node version 20.x or greater or set the `runtime` in the function config: + +```ts +export const config = { + runtime: 'nodejs20.x', +} +``` + +::: diff --git a/docs/versioned_docs/version-8.2/directives.md b/docs/versioned_docs/version-8.2/directives.md new file mode 100644 index 000000000000..d9c0d1d50119 --- /dev/null +++ b/docs/versioned_docs/version-8.2/directives.md @@ -0,0 +1,694 @@ +--- +description: Customize GraphQL execution +--- + +# Directives + +Redwood Directives are a powerful feature, supercharging your GraphQL-backed Services. + +You can think of directives like "middleware" that let you run reusable code during GraphQL execution to perform tasks like authentication and formatting. + +Redwood uses them to make it a snap to protect your API Services from unauthorized access. + +Here we call those types of directives **Validators**. + +You can also use them to transform the output of your query result to modify string values, format dates, shield sensitive data, and more! +We call those types of directives **Transformers**. + +You'll recognize a directive as being 1) preceded by `@` (e.g. `@myDirective`) and 2) declared alongside a field: + +```tsx +type Bar { + name: String! @myDirective +} +``` + +or a Query or a Mutation: + +```tsx +type Query { + bars: [Bar!]! @myDirective +} + +type Mutation { + createBar(input: CreateBarInput!): Bar! @myDirective +} +``` + +You can also define arguments that can be extracted and used when evaluating the directive: + +```tsx +type Bar { + field: String! @myDirective(roles: ["ADMIN"]) +} +``` + +or a Query or Mutation: + +```tsx +type Query { + bars: [Bar!]! @myDirective(roles: ["ADMIN"]) +} +``` + +You can also use directives on relations: + +```tsx +type Baz { + name: String! +} + +type Bar { + name: String! + bazzes: [Baz]! @myDirective +} +``` + +There are many ways to write directives using GraphQL tools and libraries. Believe us, it can get complicated fast. + +But, don't fret: Redwood provides an easy and ergonomic way to generate and write your own directives so that you can focus on the implementation logic and not the GraphQL plumbing. + +## What is a Redwood Directive? + +Redwood directives are purposeful. +They come in two flavors: **Validators** and **Transformers**. + +Whatever flavor of directive you want, all Redwood directives must have the following properties: + +- be in the `api/src/directives/{directiveName}` directory where `directiveName` is the directive directory +- must have a file named `{directiveName}.{js,ts}` (e.g. `maskedEmail.ts`) +- must export a `schema` and implement either a `validate` or `transform` function + +### Understanding the Directive Flow + +Since it helps to know a little about the GraphQL phases—specifically the Execution phase—and how Redwood Directives fit in the data-fetching and authentication flow, let's have a quick look at some diagrams. + +First, we see the built-in `@requireAuth` Validator directive that can allow or deny access to a Service (a.k.a. a resolver) based on Redwood authentication. +In this example, the `post(id: Int!)` query is protected using the `@requireAuth` directive. + +If the request's context has a `currentUser` and the app's `auth.{js|ts}` determines it `isAuthenticated()`, then the execution phase proceeds to get resolved (for example, the `post({ id })` Service is executed and queries the database using Prisma) and returns the data in the resulting response when execution is done. + +![require-auth-directive](https://user-images.githubusercontent.com/1051633/135320891-34dc06fc-b600-4c76-8a35-86bf42c7f179.png) + +In this second example, we add the Transformer directive `@welcome` to the `title` field on `Post` in the SDL. + +The GraphQL Execution phase proceeds the same as the prior example (because the `post` query is still protected and we'll want to fetch the user's name) and then the `title` field is resolved based on the data fetch query in the service. + +Finally after execution is done, then the directive can inspect the `resolvedValue` (here "Welcome to the blog!") and replace the value by inserting the current user's name—"Welcome, Tom, to the blog!" + +![welcome-directive](https://user-images.githubusercontent.com/1051633/135320906-5e2d639d-13a1-4aaf-85bf-98529822d244.png) + +### Validators + +Validators integrate with Redwood's authentication to evaluate whether or not a field, query, or mutation is permitted—that is, if the request context's `currentUser` is authenticated or belongs to one of the permitted roles. + +Validators should throw an Error such as `AuthenticationError` or `ForbiddenError` to deny access and simply return to allow. + +Here the `@isSubscriber` validator directive checks if the currentUser exists (and therefore is authenticated) and whether or not they have the `SUBSCRIBER` role. If they don't, then access is denied by throwing an error. + +```tsx +import { + AuthenticationError, + ForbiddenError, + createValidatorDirective, + ValidatorDirectiveFunc, +} from '@redwoodjs/graphql-server' +import { hasRole } from 'src/lib/auth' + +export const schema = gql` + directive @isSubscriber on FIELD_DEFINITION +` + +const validate: ValidatorDirectiveFunc = ({ context }) => { + if (!context.currentUser) { + throw new AuthenticationError("You don't have permission to do that.") + } + + if (!context.currentUser.roles?.includes('SUBSCRIBER')) { + throw new ForbiddenError("You don't have access to do that.") + } +} + +const isSubscriber = createValidatorDirective(schema, validate) + +export default isSubscriber +``` + +Since validator directives can access arguments (such as `roles`), you can quickly provide RBAC (Role-based Access Control) to fields, queries and mutations. + +```tsx +import gql from 'graphql-tag' + +import { createValidatorDirective } from '@redwoodjs/graphql-server' + +import { requireAuth as applicationRequireAuth } from 'src/lib/auth' +import { logger } from 'src/lib/logger' + +export const schema = gql` + directive @requireAuth(roles: [String]) on FIELD_DEFINITION +` + +const validate = ({ directiveArgs }) => { + const { roles } = directiveArgs + + applicationRequireAuth({ roles }) +} + +const requireAuth = createValidatorDirective(schema, validate) + +export default requireAuth +``` + +All Redwood apps come with two built-in validator directives: `@requireAuth` and `@skipAuth`. +The `@requireAuth` directive takes optional roles. +You may use these to protect against unwanted GraphQL access to your data. +Or explicitly allow public access. + +> **Note:** Validators evaluate prior to resolving the field value, so you cannot modify the value and any return value is ignored. + +### Transformers + +Transformers can access the resolved field value to modify and then replace it in the response. +Transformers apply to both single fields (such as a `User`'s `email`) and collections (such as a set of `Posts` that belong to `User`s) or is the result of a query. As such, Transformers cannot be applied to Mutations. + +In the first case of a single field, the directive would return the modified field value. In the latter case, the directive could iterate each `Post` and modify the `title` in each. In all cases, the directive **must** return the same expected "shape" of the data the SDL expects. + +> **Note:** you can chain directives to first validate and then transform, such as `@requireAuth @maskedEmail`. Or even combine transformations to cascade formatting a value (you could use `@uppercase` together with `@truncate` to uppercase a title and shorten to 10 characters). + +Since transformer directives can access arguments (such as `roles` or `maxLength`) you may fetch those values and use them when applying (or to check if you even should apply) your transformation. + +That means that a transformer directive could consider the `permittedRoles` in: + +```tsx +type user { + email: String! @maskedEmail(permittedRoles: ["ADMIN"]) +} +``` + +and if the `currentUser` is an `ADMIN`, then skip the masking transform and simply return the original resolved field value: + +```jsx title="./api/src/directives/maskedEmail.directive.js" +import { createTransformerDirective, TransformerDirectiveFunc } from '@redwoodjs/graphql-server' + +export const schema = gql` + directive @maskedEmail(permittedRoles: [String]) on FIELD_DEFINITION +` + +const transform: TransformerDirectiveFunc = ({ context, resolvedValue }) => { + return resolvedValue.replace(/[a-zA-Z0-9]/i, '*') +} + +const maskedEmail = createTransformerDirective(schema, transform) + +export default maskedEmail +``` + +and you would use it in your SDLs like this: + +```graphql +type UserExample { + id: Int! + email: String! @maskedEmail # 👈 will replace alphanumeric characters with asterisks in the response! + name: String +} +``` + +### Where can I use a Redwood Directive? + +A directive can only appear in certain locations in a GraphQL schema or operation. These locations are listed in the directive's definition. + +In the example below, the `@maskedEmail` example, the directive can only appear in the `FIELD_DEFINITION` location. + +An example of a `FIELD_DEFINITION` location is a field that exists on a `Type`: + +```graphql +type UserExample { + id: Int! + email: String! @requireAuth + name: String @maskedEmail # 👈 will maskedEmail name in the response! +} + +type Query { + userExamples: [UserExample!]! @requireAuth 👈 will enforce auth when fetching all users + userExamples(id: Int!): UserExample @requireAuth 👈 will enforce auth when fetching a single user +} +``` + +> **Note**: Even though GraphQL supports `FIELD_DEFINITION | ARGUMENT_DEFINITION | INPUT_FIELD_DEFINITION | ENUM_VALUE` locations, RedwoodDirectives can **only** be declared on a `FIELD_DEFINITION` — that is, you **cannot** declare a directive in an `Input type`: +> +> ```graphql +> input UserExampleInput { +> email: String! @maskedEmail # 👈 🙅 not allowed on an input +> name: String! @requireAuth # 👈 🙅 also not allowed on an input +> } +> ``` + +## When Should I Use a Redwood Directive? + +As noted in the [GraphQL spec](https://graphql.org/learn/queries/#directives): + +> Directives can be useful to get out of situations where you otherwise would need to do string manipulation to add and remove fields in your query. Server implementations may also add experimental features by defining completely new directives. + +Here's a helpful guide for deciding when you should use one of Redwood's Validator or Transformer directives: + +| | Use | Directive | Custom? | Type | +| --- | ---------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------- | ------------ | +| ✅ | Check if the request is authenticated? | `@requireAuth` | Built-in | Validator | +| ✅ | Check if the user belongs to a role? | `@requireAuth(roles: ["AUTHOR"])` | Built-in | Validator | +| ✅ | Only allow admins to see emails, but others get a masked value like "###@######.###" | `@maskedEmail(roles: ["ADMIN"])` | Custom | Transformer | +| 🙅 | Know if the logged in user can edit the record, and/or values | N/A - Instead do this check in your service | +| 🙅 | Is my input a valid email address format? | N/A - Instead do this check in your service using [Service Validations](services.md#service-validations) or consider [GraphQL Scalars](https://www.graphql-scalars.dev) | +| 🙅 | I want to remove a field from the response for data filtering; for example, do not include the title of the post | `@skip(if: true )` or `@include(if: false)` | Instead use [core directives](https://graphql.org/learn/queries/#directives) on the GraphQL client query, not the SDL | Core GraphQL | + +## Combining, Chaining and Cascading Directives + +Now that you've seen what Validator and Transformer directives look like and where and when you may use them, you may wonder: can I use them together? Can I transform the result of a transformer? + +The answer is: yes—yes you can! + +### Combine Directives on a Query and a Type Field + +Let's say you want to only allow logged-in users to be able to query `User` details and you only want un-redacted email addresses to be shown to ADMINs. + +You can apply the `@requireAuth` directive to the `user(id: Int!)` query so you have to be logged in. +Then, you can compose a `@maskedEmail` directive that checks the logged-in user's role membership and if they're not an ADMIN, mask the email address: + +```tsx + type User { + id: Int! + name: String! + email: String! @maskedEmail(role: "ADMIN") + createdAt: DateTime! + } + + type Query { + user(id: Int!): User @requireAuth + } +``` + +Or, let's say I want to only allow logged in users to be able to query User details. + +But, I only want ADMIN users to be able to query and fetch the email address. + +I can apply the `@requireAuth` directive to the `user(id: Int!)` query so I have to be logged in. + +And, I can apply the `@requireAuth` directive to the `email` field with a role argument. + +```tsx + type User { + id: Int! + name: String! + email: String! @requireAuth(role: "ADMIN") + createdAt: DateTime! + } + + type Query { + user(id: Int!): User @requireAuth + } +``` + +Now, if a user who is not an ADMIN queries: + +```tsx +query user(id: 1) { + id + name + createdAt +} +``` + +They will get a result. + +But, if they try to query: + +```tsx +query user(id: 1) { + id + name + email + createdAt +} +``` + +They will be forbidden from even making the request. + +### Chaining a Validator and a Transformer + +Similar to the prior example, you may want to chain directives, but the transform doesn't consider authentication or role membership. + +For example, here we ensure that anyone trying to query a User and fetch the email must be authenticated. + +And then, if they are, apply a mask to the email field. + +```tsx + type User { + id: Int! + name: String! + email: String! @requireAuth @maskedEmail + createdAt: DateTime! + } +``` + +### Cascade Transformers + +Maybe you want to apply multiple field formatting? + +If your request event headers includes geographic or timezone info, you could compose a custom Transformer directive called `@localTimezone` could inspect the header value and convert the `createdAt` from UTC to local time -- something often done in the browser. + +Then, you can chain the `@dateFormat` Transformer, to just return the date portion of the timestamp -- and not the time. + +```tsx + type User { + id: Int! + name: String! + email: String! + createdAt: DateTime! @localTimezone @dateFormat + } +``` + +> **Note**: These directives could be alternatively be implemented as "operation directives" so the client can use them on a query instead of the schema-level. These such directives are a potential future Redwood directive feature. + +## GraphQL Handler Setup + +Redwood makes it easy to code, organize, and map your directives into your GraphQL schema. +Simply add them to the `directives` directory and the `createGraphQLHandler` does all the work. + +You simply add them to the `directives` directory and the `createGraphQLHandler` will do all the work. + +> **Note**: Redwood has a generator that will do all the heavy lifting setup for you! + +```tsx title="api/src/functions/graphql.ts" +import { createGraphQLHandler } from '@redwoodjs/graphql-server' + +import directives from 'src/directives/**/*.{js,ts}' // 👈 directives live here +import sdls from 'src/graphql/**/*.sdl.{js,ts}' +import services from 'src/services/**/*.{js,ts}' + +import { db } from 'src/lib/db' +import { logger } from 'src/lib/logger' + +export const handler = createGraphQLHandler({ + loggerConfig: { logger, options: {} }, + directives, // 👈 directives are added to the schema here + sdls, + services, + onException: () => { + // Disconnect from your database with an unhandled exception. + db.$disconnect() + }, +}) +``` + +## Secure by Default with Built-in Directives + +By default, your GraphQL endpoint is open to the world. + +That means anyone can request any query and invoke any Mutation. +Whatever types and fields are defined in your SDL is data that anyone can access. + +But Redwood encourages being secure by default by defaulting all queries and mutations to have the `@requireAuth` directive when generating SDL or a service. +When your app builds and your server starts up, Redwood checks that **all** queries and mutations have `@requireAuth`, `@skipAuth` or a custom directive applied. + +If not, then your build will fail: + +```bash +✖ Verifying graphql schema... +Building API... +Cleaning Web... +Building Web... +Prerendering Web... +You must specify one of @requireAuth, @skipAuth or a custom directive for +- contacts Query +- posts Query +- post Query +- updatePost Mutation +- deletePost Mutation +``` + +or your server won't startup and you should see that "Schema validation failed": + +```bash +gen | Generating TypeScript definitions and GraphQL schemas... +gen | 47 files generated +api | Building...

But they do have access to the `context` and `directiveArgs`. +They can be async or sync. +And if you want to stop executing (because of insufficient permissions for example), throw an error. +The return value is ignored + +An example of `directiveArgs` is the `roles` argument in the directive `requireAuth(roles: "ADMIN")` + +```tsx +const validate: ValidatorDirectiveFunc = ({ context, directiveArgs }) => { + // You can also modify your directive to take arguments + // and use the directiveArgs object provided to this function to get values + logger.debug(directiveArgs, 'directiveArgs in isSubscriber directive') + + throw new Error('Implementation missing for isSubscriber') +} +``` + +Here we can access the `context` parameter and then check to see if the `currentUser` is authenticated and if they belong to the `SUBSCRIBER` role: + +```tsx title="/api/src/directives/isSubscriber/isSubscriber.ts" +// ... + +const validate: ValidatorDirectiveFunc = ({ context }) => { + if (!context.currentUser)) { + throw new AuthenticationError("You don't have permission to do that.") + } + + if (!context.currentUser.roles?.includes('SUBSCRIBER')) { + throw new ForbiddenError("You don't have access to do that.") + } +} +``` + +#### Writing Validator Tests + +When writing a Validator directive test, you'll want to: + +- ensure the directive is named consistently and correctly so the directive name maps properly when validating +- confirm that the directive throws an error when invalid. The Validator directive should always have a reason to throw an error + +Since we stub out the `Error('Implementation missing for isSubscriber')` case when generating the Validator directive, these tests should pass. +But once you begin implementing the validate logic, it's on you to update appropriately. + +```tsx +import { mockRedwoodDirective, getDirectiveName } from '@redwoodjs/testing/api' + +import isSubscriber from './isSubscriber' + +describe('isSubscriber directive', () => { + it('declares the directive sdl as schema, with the correct name', () => { + expect(isSubscriber.schema).toBeTruthy() + expect(getDirectiveName(isSubscriber.schema)).toBe('isSubscriber') + }) + + it('has a isSubscriber throws an error if validation does not pass', () => { + const mockExecution = mockRedwoodDirective(isSubscriber, {}) + + expect(mockExecution).toThrowError( + 'Implementation missing for isSubscriber' + ) + }) +}) +``` + +:::tip +If your Validator Directive is asynchronous, you can use `rejects` to handle the exception. + +```ts +describe('isSubscriber directive', () => { + it('has a isSubscriber throws an error if validation does not pass', async () => { + const mockExecution = mockRedwoodDirective(isSubscriber, {}) + await expect(mockExecution()).rejects.toThrowError( + 'Implementation missing for isSubscriber' + ) + }) +}) +``` + +::: + +### Transformer + +Let's create a `@maskedEmail` directive that checks roles to see if the user should see the complete email address or if it should be obfuscated from prying eyes: + +```bash +yarn rw g directive maskedEmail --type transformer +``` + +Next, implement your validation logic in the directive's `transform` function. + +Transformer directives provide `context` and `resolvedValue` parameters and run **after** resolving the value. +Transformer directives **must** be synchronous, and return a value. +You can throw an error, if you want to stop executing, but note that the value has already been resolved. + +Take note of the `resolvedValue`: + +```tsx +const transform: TransformerDirectiveFunc = ({ context, resolvedValue }) => { + return resolvedValue.replace('foo', 'bar') +} +``` + +It contains the value of the field on which the directive was placed.

You'll just have to read your provider's documentation. +Some hosting providers distinguish between build and runtime environments for configuring environment variables. Environment variables for the api side should in those cases be configured as runtime variables. + +## Keeping Sensitive Information Safe + +Since it usually contains sensitive information, you should [never commit your `.env` file](https://github.com/motdotla/dotenv#should-i-commit-my-env-file). Note that you'd actually have to go out of your way to do this as, by default, a Redwood app's `.gitignore` explicitly ignores `.env`: + +```plaintext {2} +.DS_Store +.env +.netlify +dev.db +dist +dist-babel +node_modules +yarn-error.log +``` + +## Where Does Redwood Load My Environment Variables? + +For all the variables in your `.env` and `.env.defaults` files to make their way to `process.env`, there has to be a call to `dotenv`'s `config` function somewhere.
