Wrapper to easily enable hot-reload for shelf applications.
import 'dart:io';
import 'package:shelf/shelf.dart' as shelf;
import 'package:shelf/shelf_io.dart' as io;
import 'package:shelf_hotreload/shelf_hotreload.dart';
// Run this app with --enable-vm-service (or use debug run)
void main() async {
withHotreload(() => createServer());
}
Future<HttpServer> createServer() {
handler(shelf.Request request) => shelf.Response.ok('hot!');
return io.serve(handler, 'localhost', 8080);
}In order to enable hot-reload, you need to run your Dart application with --enable-vm-service (or use debug run in your IDE).
For example:
dart run --enable-vm-service path/to/app.dart
You can also also modify the default logging by providing callbacks:
final myLogger = Logger();
withHotreload(
() => createServer(),
onReloaded: () => myLogger.log('Reload!'),
onHotReloadNotAvailable: () => myLogger.log('No hot-reload :('),
onHotReloadAvailable: () => myLogger.log('Yay! Hot-reload :)'),
onHotReloadLog: (log) => myLogger.log('Reload Log: ${log.message}'),
logLevel: Level.INFO,
);
