RxJS subscription sink for unsubscribing gracefully in a component.
SubSink is a dead simple class to absorb RxJS subscriptions in an array.
Call unsubscribe() to unsubscribe all of them, as you would do
in your component library's unmount/onDestroy lifecycle event.
npm install subsink --save
export class SomeComponent implements OnDestroy {
private subs = new SubSink();
...
this.subs.sink = observable$.subscribe(...); // easy syntax
this.subs.add(observable$.subscribe(...)); // if you insist
this.subs.add( // can add multiple subcriptions
observable$.subscribe(...),
anotherObservable$.subscribe(...)
);
...
// Unsubscribe when the component dies
ngOnDestroy() {
this.subs.unsubscribe();
}
}
