JavaScript version of "Hello World" is 5570kb

[andersforsell]

Can the annotation "@MirrorsUsed" be used to help dart2js reduce the size of the JavaScript? (I think it was done for Polymer apps lately).

I am working on this problem.

Added a @MirrorsUsed to main.dart reduces this number to 182K minified and compressed.

I used:

@MirrorsUsed(targets: const[
  'angular',
  'angular.core',
  'angular.core.dom',
  'angular.filter',
  'angular.perf',
  'angular.directive',
  'angular.routing',
  'angular.core.parser',
  'NodeTreeSanitizer'
  ],
  override: '*')
import 'dart:mirrors';

@jbdeboer Good idea to track the size using a tool. Just a question: shouldn't the MirrorsUsed annotation be part of the Angular library and not have to be specified in the user's code?

[jbdeboer]

Maybe, but um not sure how that works. If you could put together a pull
request we would gladly accept it.

Following the AngularDart tutorial, step one, generated > 3MB of javascript. Can we reopen this issue?

(BTW I'm using 0.9.3)

I edited angular.dart:

@MirrorsUsed(targets: const[
  'angular',
  'angular.core',
  'angular.core.dom',
  'angular.filter',
  'angular.perf',
  'angular.directive',
  'angular.routing',
  'angular.core.parser',
  'NodeTreeSanitizer'
  ],
  override: '*')
import 'dart:mirrors';
