sharedWorker.port.onmessage doesn't seem to be covered by NgZone
See original GitHub issue🐞 bug report
Affected Package
The issue is caused by package @angular/zone.js
Is this a regression?
I don’t think so.
Description
We are using a SharedWorker to synchronize data between multiple open tabs. We ran into some very weird behaviors where the displayed data would only change if you e.g. click on the page (= trigger for change detection).
We could finally track it down to the following root:
sharedWorker = new SharedWorker('shared-worker.js');
sharedWorker.port.onmessage = (event: MessageEvent) => {
// here is some logic to transport the received data around the application via rxjs Subjects
// these subjects didn't trigger change-detection anywhere
}
It could be fixed by letting it manually run in the zone (zone: NgZone)
sharedWorker = new SharedWorker('shared-worker.js');
sharedWorker.port.onmessage = (event: MessageEvent) => {
this.zone.run(()=> {
// here is some logic to transport the received data around the application via rxjs Subjects
// now change-detection is everywhere triggered as expected
});
}

I currently don#t have time to create a full reproduction in stackblitz - if necessary I will add it later on…
