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:

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.
