A high-powered HTTP server with support for dependency injection, sophisticated routing and more.
|
|
|
|
This is the core of the [Angel](https://github.com/angel-dart/angel) framework.
|
|
To build real-world applications, please see the [homepage](https://angel-dart.github.io).
|
|
|
|
```dart
|
|
import 'package:angel_framework/angel_framework.dart';
|
|
|
|
main() async {
|
|
var app = new Angel();
|
|
|
|
// Index route. Returns JSON.
|
|
app.get('/', () => 'Welcome to Angel!');
|
|
|
|
// Accepts a URL like /greet/foo or /greet/bob.
|
|
app.get('/greet/:name', (String name) => 'Hello, $name!');
|
|
|
|
// Pattern matching - only call this handler if the query value of `name` equals 'emoji'.
|
|
app.get('/greet', (@Query('name', match: 'emoji') String name) => '😇🔥🔥🔥');
|
|
|
|
// Handle any other query value of `name`.
|
|
app.get('/greet', (@Query('name') String name) => 'Hello, $name!');
|
|
|
|
// Simple fallback to throw a 404 on unknown paths.
|
|
app.use((RequestContext req) async {
|
|
throw new AngelHttpException.notFound(
|
|
message: 'Unknown path: "${req.uri.path}"',
|
|
);
|
|
});
|
|
|
|
var http = new AngelHttp(app);
|
|
var server = await http.startServer('127.0.0.1', 3000);
|
|
var url = 'http://${server.address.address}:${server.port}';
|
|
print('Listening at $url');
|
|
print('Visit these pages to see Angel in action:');
|
|
print('* $url/greet/bob');
|
|
print('* $url/greet/?name=emoji');
|
|
print('* $url/greet/?name=jack');
|
|
print('* $url/nonexistent_page');
|
|
}
