Are you sure you are using the latest version? Angular was an early user of mirrors (reflection) which (more or less) disabled the tree-shaking of dart2js. This was recently improved.

Maybe I'm missing something, but yes, I think so. Dart version 0.8.10.3_r29803.

pubspec.yaml:

name: test1 dependencies: browser: any angular: git: https://github.com/angular/angular.dart.git

test1.dart:

import 'package:angular/angular.dart'; main() => ngBootstrap();

dart2js launch => builds test1.dart.js, about 5MB, 142,749 loc.

Yes. You need to add a @MirrorsUsed annotation in your main.dart file. See https://github.com/jbdeboer/angular-dart-js-size/blob/master... for our current best practices.

You should get ~173KB gzipped, minified dart2js output.

Beautiful. Thanks!

So are you using that the full tree shaking algo works with angular now?
