Unsubscription using SwPush

control-push.component.ts

  unsubscribeFromPush() {

    // Get active subscription

    this.swPush.subscription
      .take(1)
      .subscribe(pushSubscription => {

        console.log('[App] pushSubscription', pushSubscription)

        // Delete the subscription from the backend

        this.pushService.deleteSubscriber(pushSubscription)
          .subscribe(

          res => {
            console.log('[App] Delete subscriber request answer', res)

            let snackBarRef = this.snackBar.open('Now you are unsubscribed', null, {
              duration: this.snackBarDuration
            });

            // Unsubscribe current client (browser)

            pushSubscription.unsubscribe()
              .then(success => {
                console.log('[App] Unsubscription successful', success)
              })
              .catch(err => {
                console.log('[App] Unsubscription failed', err)
              })

          },
          err => {
            console.log('[App] Delete subscription request failed', err)
          }

          )

      })

  }

Hello @webmaxru,

Got this error
Property 'take' does not exist on type 'Observable<PushSubscription>'.

Thanks.

@bolajipemipo i think this is because you are using rxjs 5.5+ and the syntax changed.
use new lettable/pipable import statements in the file header:
import { map, catchError, take .. } from 'rxjs/operators';
and you should use take in a pipe:

 this.swPush.subscription
      .pipe(take(1))
      .subscribe(pushSubscription => {

        console.log('[App] pushSubscription', pushSubscription)

        // Delete the subscription from the backend

If you want to use more operators use them like below:

 this.swPush.subscription
      .pipe(
          take(1),
          map(val => val),
          filter(val => val)
      )
      .subscribe(pushSubscription => {

        console.log('[App] pushSubscription', pushSubscription)

@petivagyok16 Can you please explain why you need to pipe the subscription?

I try to unsubscribe and can get it to work with or without pipe. pushSubscription is always null in my case although I'm sure that I'm subscribed (because I get notifications). Why? How to make it work? Unfortunately, there is no document.
