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:

• Async stack traces in Chrome
• 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.
