| 10 | +### NPM scripts |
| 11 | + |
| 12 | +- `npm t`: Run test suite |
| 13 | +- `npm start`: Run `npm run build` in watch mode |
| 14 | +- `npm run test:watch`: Run test suite in [interactive watch mode](http://facebook.github.io/jest/docs/cli.html#watch) |
| 15 | +- `npm run test:prod`: Run linting and generate coverage |
| 16 | +- `npm run build`: Generate bundles and typings, create docs |
| 17 | +- `npm run lint`: Lints code |
| 18 | +- `npm run commit`: Commit using conventional commit style ([husky](https://github.com/typicode/husky) will tell you to use it if you haven't :wink:) |
| 19 | + |
| 20 | +### Excluding peerDependencies |
| 21 | + |
| 22 | +On library development, one might want to set some peer dependencies, and thus remove those from the final bundle. You can see in [Rollup docs](https://rollupjs.org/#peer-dependencies) how to do that. |
| 23 | + |
| 24 | +Good news: the setup is here for you, you must only include the dependency name in `external` property within `rollup.config.js`. For example, if you want to exclude `lodash`, just write there `external: ['lodash']`. |
| 25 | + |
| 26 | +### Automatic releases |
| 27 | + |
| 28 | +_**Prerequisites**: you need to create/login accounts and add your project to:_ |
| 29 | + |
| 30 | +- [npm](https://www.npmjs.com/) |
| 31 | +- [Travis CI](https://travis-ci.org) |
| 32 | +- [Coveralls](https://coveralls.io) |
| 33 | + |
| 34 | +_**Prerequisite for Windows**: Semantic-release uses |
| 35 | +**[node-gyp](https://github.com/nodejs/node-gyp)** so you will need to |
| 36 | +install |
| 37 | +[Microsoft's windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) |
| 38 | +using this command:_ |
| 39 | + |
| 40 | +```bash |
| 41 | +npm install --global --production windows-build-tools |
| 42 | +``` |
| 43 | + |
| 44 | +#### Setup steps |
| 45 | + |
| 46 | +Follow the console instructions to install semantic release and run it (answer NO to "Do you want a `.travis.yml` file with semantic-release setup?"). |
| 47 | + |
| 48 | +_Note: make sure you've setup `repository.url` in your `package.json` file_ |
| 49 | + |
| 50 | +```bash |
| 51 | +npm install -g semantic-release-cli |
| 52 | +semantic-release-cli setup |
| 53 | +# IMPORTANT!! Answer NO to "Do you want a `.travis.yml` file with semantic-release setup?" question. It is already prepared for you :P |
| 54 | +``` |
| 55 | + |
| 56 | +From now on, you'll need to use `npm run commit`, which is a convenient way to create conventional commits. |
| 57 | + |
| 58 | +Automatic releases are possible thanks to [semantic release](https://github.com/semantic-release/semantic-release), which publishes your code automatically on [github](https://github.com/) and [npm](https://www.npmjs.com/), plus generates automatically a changelog. This setup is highly influenced by [Kent C. Dodds course on egghead.io](https://egghead.io/courses/how-to-write-an-open-source-javascript-library) |
| 59 | + |
| 60 | +### Git Hooks |
| 61 | + |
| 62 | +There is already set a `precommit` hook for formatting your code with Prettier :nail_care: |
| 63 | + |
| 64 | +By default, there are two disabled git hooks. They're set up when you run the `npm run semantic-release-prepare` script. They make sure: |
| 65 | + |
| 66 | +- You follow a [conventional commit message](https://github.com/conventional-changelog/conventional-changelog) |
| 67 | +- Your build is not going to fail in [Travis](https://travis-ci.org) (or your CI server), since it's runned locally before `git push` |
| 68 | + |
| 69 | +This makes more sense in combination with [automatic releases](#automatic-releases) |
| 70 | + |
| 71 | +### FAQ |
| 72 | + |
| 73 | +#### `Array.prototype.from`, `Promise`, `Map`... is undefined? |
| 74 | + |
| 75 | +TypeScript or Babel only provides down-emits on syntactical features (`class`, `let`, `async/await`...), but not on functional features (`Array.prototype.find`, `Set`, `Promise`...), . For that, you need Polyfills, such as [`core-js`](https://github.com/zloirock/core-js) or [`babel-polyfill`](https://babeljs.io/docs/usage/polyfill/) (which extends `core-js`). |
| 76 | + |
| 77 | +For a library, `core-js` plays very nicely, since you can import just the polyfills you need: |
| 78 | + |
| 79 | +```javascript |
| 80 | +import "core-js/fn/array/find" |
| 81 | +import "core-js/fn/string/includes" |
| 82 | +import "core-js/fn/promise" |
| 83 | +... |
| 84 | +``` |
| 85 | + |
| 86 | +#### What is `npm install` doing on first run? |
| 87 | + |
| 88 | +It runs the script `tools/init` which sets up everything for you. In short, it: |
| 89 | + |
| 90 | +- Configures RollupJS for the build, which creates the bundles |
| 91 | +- Configures `package.json` (typings file, main file, etc) |
| 92 | +- Renames main src and test files |
| 93 | + |
| 94 | +#### What if I don't want git-hooks, automatic releases or semantic-release? |
| 95 | + |
| 96 | +Then you may want to: |
| 97 | + |
| 98 | +- Remove `commitmsg`, `postinstall` scripts from `package.json`. That will not use those git hooks to make sure you make a conventional commit |
| 99 | +- Remove `npm run semantic-release` from `.travis.yml` |
| 100 | + |
| 101 | +#### What if I don't want to use coveralls or report my coverage? |
| 102 | + |
| 103 | +Remove `npm run report-coverage` from `.travis.yml` |
