Zone.js

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:

strongloop/zone (Deprecated)
vizone - control flow visualizer that uses zone.js

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
