Read in a JS variable called STATIC_URL and use that for static files loaded in an angular.dart application

cdnrewriter.dart

import 'package:angular/angular.dart';
import 'package:js/js.dart' as js;

class CDNRewriter implements UrlRewriter {
  String staticUrl;

  CDNRewriter() {
    var context = js.context;
    staticUrl = js.context.STATIC_URL;
  }

  String call(String url) {
    if (url.startsWith('/static/')) {
      return _rewriteCdnUrl(url);
    }
    return url;
  } 

  String _rewriteCdnUrl(String url) {
    return url.replaceFirst(new RegExp(r'/static/'), staticUrl);
  }
}
