JiaLiPassion 31796e8e2f fix(zone.js): remove unused Promise overwritten setter logic (#36851)
In the early Zone.js versions (< 0.10.3), `ZoneAwarePromise` did not support `Symbol.species`,
so when user used a 3rd party `Promise` such as `es6-promise`, and try to load the promise library after import of `zone.js`, the loading promise library will overwrite the patched `Promise` from `zone.js` and will break `Promise` semantics with respect to `zone.js`.

Starting with `zone.js` 0.10.3, `Symbol.species` is supported therefore this will not longer be an issue. (https://github.com//pull/34533)

Before 0.10.3, the logic in zone.js tried to handle the case in the wrong way. It did so by overriding the descriptor of `global.Promise`, to allow the 3rd party libraries to override native `Promise` instead of `ZoneAwarePromise`. This is not the correct solution, and since the `Promise.species` is now supported, the 3rd party solution of overriding `global.Promise` is no longer needed.

PR removes the wrong work around logic. (This will improve the bundle size.)

Zone.js

CDNJS

Implements Zones for JavaScript, inspired by Dart.

If you're using zone.js via unpkg (i.e. using https://unpkg.com/zone.js) and you're using any of the following libraries, make sure you import them first

  • 'newrelic' as it patches global.Promise before zone.js does
  • 'async-listener' as it patches global.setTimeout, global.setInterval before zone.js does
  • 'continuation-local-storage' as it uses async-listener

NEW Zone.js POST-v0.6.0

See the new API here.

Read up on Zone Primer.

What's a Zone?

A Zone is an execution context that persists across async tasks. You can think of it as thread-local storage for JavaScript VMs.

See this video from ng-conf 2014 for a detailed explanation:

Standard API support

zone.js patched most standard web APIs (such as DOM events, XMLHttpRequest, ...) and nodejs APIs (EventEmitter, fs, ...), for more details, please see STANDARD-APIS.md.

Nonstandard API support

We are adding support to some nonstandard APIs, such as MediaQuery and Notification. Please see NON-STANDARD-APIS.md for more details.

Examples

You can find some samples to describe how to use zone.js in SAMPLE.md.

Modules

zone.js patches the async APIs described above, but those patches will have some overhead. Starting from zone.js v0.8.9, you can choose which web API module you want to patch. For more details, please see MODULE.md.

Bundles

There are several bundles under dist folder.

Bundle Summary
zone.js the default bundle, contains the most used APIs such as setTimeout/Promise/EventTarget..., also this bundle supports all evergreen and legacy (IE/Legacy Firefox/Legacy Safari) Browsers
zone-evergreen.js the bundle for evergreen browsers, doesn't include the patch for legacy browsers such as IE or old versions of Firefox/Safari
zone-legacy.js the patch bundle for legacy browsers, only includes the patch for legacy browsers such as IE or old versions of Firefox/Safari. This bundle must be loaded after zone-evergreen.js, zone.js=zone-evergreen.js + zone-legacy.js
zone-testing.js the bundle for zone testing support, including jasmine/mocha support and async/fakeAsync/sync test utilities
zone-externs.js the API definitions for closure compiler

And here are the additional optional patches not included in the main zone.js bundles

webapis-media-query.js patch for MediaQuery APIs
webapis-notification.js patch for Notification APIs
webapis-rtc-peer-connection.js patch for RTCPeerConnection APIs

zone-bluebird.js patch for Bluebird APIs
zone-error.js patch for Error Global Object, supports remove Zone StackTrace
