A forked version of zone.js, focusing on continuation-local-storage and without error-handling responsibilities for zones.
See the angular zone.js package for general information about zones, but recognize that onHandleError is explicitly removed from this package.
Use this package if you wanted continuation-local-storage as for node, but you wanted it to run in the browser. That's the core vision for Zones, as in zone.js's README:
A Zone is an execution context that persists across async tasks. You can think of it as thread-local storage for JavaScript VMs.
It turns out that putting error-handling responsibility into the zone stack causes some significant unwanted results, some of them stemming from zone.js's tendency to catch errors and rethrow them even when there's no onHandleError in the zone.
And when the LongStackTraceZone spec is used at the top level, it gets notified of errors in async-function-promises even when their callers are prepared to catch the error...
[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.
zoned-cls inherits these patches.
We are adding support to some nonstandard APIs, such as MediaQuery and Notification. Please see NON-STANDARD-APIS.md for more details.
You can find some samples to describe how to use zone.js in SAMPLE.md.
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.
There are several bundles under
distfolder.
no guarantees whether these will work, but feel free to give it a shot.

| 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 |
