hot #

Pub

Screenshot of terminal

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.

Installation #

In your pubspec.yaml:

dependencies:
  angel_framework: ^2.0.0-alpha
  angel_hot: ^2.0.0

Usage #

This package is dependent on the Dart VM service, so you must run Dart with the --observe (or --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 not recommended, unless you are specifically intending for a "hot code push" in production..

You can watch:

  • Files
  • Directories
  • Globs
  • URI's
  • package: URI's
import 'dart:async';
import 'dart:convert';
import 'dart:io';
import 'package:angel_framework/angel_framework.dart';
import 'package:angel_hot/angel_hot.dart';
import 'package:logging/logging.dart';
import 'src/foo.dart';

main() async {
  var hot = new HotReloader(createServer, [
    new Directory('src'),
    new Directory('src'),
    'main.dart',
    Uri.parse('package:angel_hot/angel_hot.dart')
  ]);
  await hot.startServer('127.0.0.1', 3000);
}

Future<Angel> createServer() async {
  var app = new Angel()..serializer = json.encode;

  // Edit this line, and then refresh the page in your browser!
  app.get('/', (req, res) => {'hello': 'hot world!'});
  app.get('/foo', (req, res) => new Foo(bar: 'baz'));

  app.fallback((req, res) => throw new AngelHttpException.notFound());

  app.encoders.addAll({
    'gzip': gzip.encoder,
    'deflate': zlib.encoder,
  });

  app.logger = new Logger('angel')
    ..onRecord.listen((rec) {
      print(rec);
      if (rec.error != null) {
        print(rec.error);
        print(rec.stackTrace);
      }
    });

  return app;
}

2.0.4 #

  • Forcibly close app loggers on shutdown.

2.0.3 #

  • Fixed up manual restart.
  • Remove stutter on hotkey press.

2.0.2 #

  • Fixed for compatibility with package:angel_websocket@^2.0.0-alpha.5.

2.0.1 #

2.0.0 #

  • Update for Dart 2 + Angel 2.

1.1.1+1 #

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

1.1.1 #

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

example/main.dart

import 'dart:io';
import 'package:angel_hot/angel_hot.dart';
import 'server.dart';

main() async {
  var hot = new HotReloader(createServer, [
    new Directory('src'),
    new Directory('src'),
    'server.dart',
    // Also allowed: Platform.script,
    Uri.parse('package:angel_hot/angel_hot.dart')
  ]);
  await hot.startServer('127.0.0.1', 3000);
