• NEW Multiple Routers with basePath

void main() async {
  var app = createApp(
    port: 5173,
    onRequest: (event) {
      // PER REQUEST local state😻
      event.context["user"] = 'Ogunlepon';

      setResponseHeader(event,
          header: HttpHeaders.contentTypeHeader,
          value: 'text/html; charset=utf-8');
    },
    afterResponse: (event) => {},
  );

  var router = createRouter();
  var apiRouter = createRouter();

  app.use(router, basePath: '/');
  app.use(apiRouter, basePath: '/api');

  router.get("/vamos/:id/base/:studentId", (event) {
    return event.params;
  });

  apiRouter.get("/signup", (event) async {
    var formData = await readFormData(event);

    var username = formData.get('username');
    var password = formData.get('password');

    // userService.signup(username, password);
    event.statusCode = 201;

    return 'Hi from /api with $username, $password';
  });
}

• NEW readFormData utility - familiar formdata parsing API

apiRouter.get("/signup", (event) async  {
  var formData = await readFormData(event);

  var username = formData.get('username');
  var password = formData.get('password');

  // ALSO included..
  var allNames = formdata.getAll('names') // return List<String>

  userService.signup(username, password);
  event.statusCode = 201;

  return 'Hi from /api';
});

• PATCHED all bugs in the behaviour of param routes.

0.2.0 (Minor)

• Added the start command to the CLI, H4 start which starts your app locally.

  h4 start

  or

  dart pub global run h4:start

  --dev flag

  • Run the command with the --dev flag to restart the server when you make changes to your files

• New Utilities

  • getQuery
  • setResponseHeader
  • getHeader

0.1.4

• Release

  • Added a basic CLI that bootstraps a H4 app

    • The H4 init command bootstraps a full H4 app.

    dart pub global activate h4

    then run

    h4 init

    or

    dart pub global run h4:init

0.1.3

• Release

  • Deprecated app.onRequest() signature for registering middleware.
  • Added new signature for adding middleware to requests.

  var app = createApp(
    port: 5173,
    onRequest: (event) => {},
    onError: (error, stacktrace, event) => {},
    afterResponse: (event) => {},
  );
  var router = createRouter();
  app.use(router);

  • Error handling in async handlers has been refactored and improved.
  • Certain edge cases with wildcard routing patterns were addressed.
  • Stream (SSE) implementation removed for now to study StreamSinks.

0.1.2

• Patch Release

  • Improved logic for re-assigning localhost port to start server on when designated port is in use.
  • Added a naive stream (SSE) implementation.

0.1.1

• Patch Release

  • When the port assigned to server is taken, it now informs you that the port is taken and tries to start the server on port - (previousPort + 1).
  • Improved documentation comments for the added utilities in the last release.

0.1.0

• First Minor Release

  • Added new getQueryParams utility for extracting query params in the request URL
  • Added new getHeader utility to get specific headers from the incoming request
  • Added new getRequestHeaders utility to get all defined request headers
  • Added new setResponseHeaders utility to manually set response headers

0.0.5

• New & Improved

  • Improved internal composition for handling responses of different response types and setting content type headers.

  • Improved error handling when Futures are returned from handlers.

  • New readRequestBody utility - Can only read json and text right now. Support for more body types to be added.

    router.post("/vamos", (event) async {
      var body = await readRequestBody(event);
      return body;
    });

• TODO

  • Allow handler to set content type of response with setResponseHeaders utility.

0.0.4

• New

  • Improved error handling for asynchronous event handlers - Throwing an error in an async handler won't kill the process. It sends a JSON payload instead.

    {
    	"message": "Error message",
    	"statusMessage": "Internal server error",
    	"statusCode": 500
    }

    TODO - onError handler does not run when errors are thrown async event handlers. (Fix in next few patches)

  • Support for extended server configuration : You can now specify if you want to start automatically or not. In the future you will be able to pass your own customer server and listen to requests with H4.

      void main() async {
        var app = createApp(port: 4000, autoStart: false);
        await app.start().then((h4) => print('App is running on ${h4?.port}'));
        var router = createRouter();
        app.use(router)
      };

0.0.3

• New

  • Breaking Changes to onError middleware.

    • The function passed to onError Middleware now has access to the error object (in string form), the stacktrace of the error (also in string form) and the event that triggered the error.

      h4.onError((String error, String stackTrace, H4Event event) {
        // Log the error to a service like sentry.
        logErrorToService(error, stackTrace, event.path);
      });

    • Documentation comments for public and internal API's including the H4 Class, defineEventHandler, H4Event and H4Router.

0.0.2

• New

  • requestBody utility: The first H4 utility function (readBody) is underway but not ready for production use.

    • Improved implementation of parseRequestBody correctly parses request body in non-binary, non-file formats as a string and returns the value.

  • Documentation for H4 router

  • Documentation and type definitions event handler

    • Renamed HandlerFunc type definition to EventHandler
    • Added documentation for Event Handler functions.

  • Made router[requestMethod] instances generic for increased type safety.

      // This gives an error.
      router.get<String>("/25/**", (event) => true);
    
      // This is valid
      router.get<bool>("/25/**", (event) => true);

  • Improved predictability of event handler responses: You can now return more types of values from event handlers.

  • Removed unecessary logs.

  • Used logger library when necessary to log.

• Improved

  • CreateError Utility : It now uses named parameters for message and errorCode.

   router.get("/vamos", (event) {
   throw CreateError(message: 'Error occured', errorCode: 400);
  });

0.0.1

• Initial development release.

Retraction Notice

Previous releases and versions 1.0.0, 1.0.1 and 1.1.0 were retracted due to immature development on the author's part.

Apologies for any distruptions, we are now prioritizing mature and stable development over speed.
