Add notificationCloses to SwPush #52244

Which @angular/* package(s) are relevant/related to the feature request?

service-worker

Description

Angular official documentation page says:

When using the Angular service worker, push notification interactions are handled using the SwPush service. To learn more about the browser APIs involved see Push API and Using the Notifications API.

The SwPush service contains notificationClicks property to handle serviceWorkerGlobalScope.notificationclick.

But serviceWorkerGlobalScope also emits notificationclose event.

Proposed solution

Add notificationCloses property to SwPush service.

Proposed steps:

• Add this.scope.addEventListener('notificationclose', (event) => this.onClose(event!)); (similar to already existed notificationclick event)
  

  angular/packages/service-worker/worker/src/driver.ts

  Line 172 in 634c529

  this.scope.addEventListener('notificationclick', (event) => this.onClick(event!));

• Add this.notificationCloses = this.sw.eventsOfType('NOTIFICATION_CLOSE') (similar to already existed NOTIFICATION_CLICK)
  

  angular/packages/service-worker/src/push.ts

  Lines 148 to 149 in 634c529

  	this.notificationClicks =
  	this.sw.eventsOfType('NOTIFICATION_CLICK').pipe(map((message: any) => message.data));
