Hot reloader for Dart

Docs

Reloading application on file modification

[HotReloader] lets the application hot reload itself on modifications to desired files.

main() async {
  final reloader = new HotReloader();
  reloader.addPath('.');
  await reloader.go();

  // TODO your code here!
}

VM service

[HotReloader] requires that VM service is enabled during program run for reloading to work. To enable VM services supply either --enable-vm-service or --observe command line flag when the application is run.

Failing to do so will result in notHotReloadable exception.

More information can be found at Dart VM

Debouncing

When there are too many changes, it is not efficient to reload the application for every change. Debouncing allows [HotReloader] to reload only once every specified interval. debounceInterval defaults to once every second.

main() async {
  final reloader = new HotReloader(debounceInterval: const Duration(seconds: 10));
  reloader.addPath('.');
  await reloader.go();

  // TODO your code here!
}

Adding paths to listen

Using String path

addPath method shall be used to register file/directory path as [String].

main() async {
    final reloader = new HotReloader();
    reloader.addPath('lib/');
    await reloader.go();
    
    // Your code goes here
}

Using Glob

addGlob shall be used to register multiple files/directories using a [Glob].

main() async {
    final reloader = new HotReloader();
    reloader.addGlob(new Glob('jaguar_*/lib'));
    await reloader.go();
    
    // Your code goes here
}

Using FileSystemEntity

addFile shall be used to register a FileSystemEntity.

main() async {
    final reloader = new HotReloader();
    reloader.addFile(new File('pubspec.yaml'));
    await reloader.go();
    
    // Your code goes here
}

Using Uri

addUri shall be used to register a path using an instance of [Uri].

main() async {
    final reloader = new HotReloader();
    reloader.addUri(new Uri(scheme: 'file', path: '/usr/lib/dart'));
    await reloader.go();
    
    // Your code goes here
}

Using package Uri

addPackagePath shall be used to register a path using package uri.

main() async {
    final reloader = new HotReloader();
    await reloader.addPackagePath(new Uri(scheme: 'package', path: 'jaguar/'));
    await reloader.go();
    
    // Your code goes here
}

Using package dependencies

addPackageDependencies shall be used to register all packages the current package depends on.

main() async {
    final reloader = new HotReloader();
    await reloader.addPackageDependencies();
    await reloader.go();
    
    // Your code goes here
}

Manually reloading the application

reload method is publicly available to request for application reload when desired.

Event

File modification event

onChange stream is fired every time there is a change in the registered file paths.

Reload event

onReload stream is fired after the application is reloaded irrespective of whether the file change or the user triggered the reload.
