jaspr_router 0.2.2

A routing component for jaspr.

jaspr_router

A simple Router component for jaspr

dart pub add jaspr_router

Use can use the Router component for some basic routing. It takes a list of Routes. A simple use looks like this:

import 'pages/home.dart';
import 'pages/about.dart' ;

class App extends StatelessComponent {
  @override
  Iterable<Component> build(BuildContext context) sync* {
    yield Router(routes: [
      Route(path: '/', builder: (context, state) => Home()),
      Route(path: '/about', builder: (context, state) => About()),
    ]);
  }
}

jaspr_router is adapted from the go_router flutter package. If you know go_router a lot of the core concepts should feel familiar.

To push a new route call Router.of(context).push('/path'); inside your child components. Similarly, you can call .replace() or .back().

🐨 Lazy Routes & Code Splitting

For larger web apps, we don't want to load everything together, but rather split our pages into smaller chunks. jaspr can do this automatically using LazyRoutes and deferred imports.

To use lazy routes, change the above code to the following:

import 'pages/home.dart';
import 'pages/about.dart' deferred as about;

class App extends StatelessComponent {
  @override
  Iterable<Component> build(BuildContext context) sync* {
    yield Router(
      routes: [
        Route(path: '/', builder: (context, state) => Home()),
        Route.lazy(path: '/about', builder: (context, state) => about.About(), load: about.loadLibrary),
      ],
    );
  }
}

This will lazy load the appropriate javascript files for the '/about' route when navigating to it.
