Supports hot reloading of Angel servers on file changes. This is faster and more reliable than merely reactively restarting a Process.

This package only works with the Angel framework.


In your pubspec.yaml:

  angel_hot: ^1.0.0


This package is dependent on the Dart VM service, so you must run Dart with the --enable-vm-service argument!!!

Usage is fairly simple. Pass a function that creates an Angel server, along with a collection of paths to watch, to the HotReloader constructor. The rest is history!!!

The recommended pattern is to only use hot-reloading in your application entry point. Create your Angel instance within a separate function, conventionally named createServer.

Using this in production mode is pointless.

import 'src/foo.dart';

main() async {
  var hot = new HotReloader(createServer, [
    new Directory('config'),
    new Directory('lib'),
    new Directory('web'),
    new Directory('src'),
  var server = await hot.startServer(InternetAddress.LOOPBACK_IP_V4, 3000);
      'Hot server listening at http://${server.address.address}:${server.port}');

Future<Angel> createServer() async {
  var app = new Angel();

  app.lazyParseBodies = true;

  app.get('/', {'hello': 'hot world!'});'/foo/bar', (req, res) async {
    var result = await someLengthyOperation();
    return {'status': result};

  app.after.add(() => throw new AngelHttpException.notFound());

  await app.configure(logRequests());
  return app;


  • Fix a bug that threw when --observe was not present.


  • Disable the observatory from pausing the isolate on exceptions, because Angel already handles all exceptions by itself.
