You get a subscription from .subscribe(). Use its unsubscribe() method to cancel the subscription.
@Component({
selector: 'receiver',
template: `Count: {{count}}`,
})
export class ReceiverComponent {
public count = 0;
private subscription;
constructor(private eventService:EventService) {
this.subscription = this.eventService.myEvent.subscribe(() => this.count++;);
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
