5 | * This file is divided into 2 sections:
6 | * 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
7 | * 2. Application imports. Files imported after ZoneJS that should be loaded before your main
8 | * file.
9 | *
10 | * The current setup is for so-called "evergreen" browsers; the last versions of browsers that
11 | * automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
12 | * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.

33 | * user can disable parts of macroTask/DomEvents patch by setting following flags
34 | * because those flags need to be set before `zone.js` being loaded, and webpack
35 | * will put import in the top of bundle, so user need to create a separate file
36 | * in this directory (for example: zone-flags.ts), and put the following flags
37 | * into that file, and then add the following code before importing zone.js.
38 | * import './zone-flags.ts';
39 | *
40 | * The flags allowed in zone-flags.ts are listed here.
41 | *
42 | * The following flags will work for all browsers.
43 | *
44 | * (window as any).__Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
45 | * (window as any).__Zone_disable_on_property = true; // disable patch onProperty such as onclick
46 | * (window as any).__zone_symbol__UNPATCHED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
47 | *
48 | * in IE/Edge developer tools, the addEventListener will also be wrapped by zone.js
49 | * with the following flag, it will bypass `zone.js` patch for IE/Edge
