ngx-until-destroy

Reduce your boilerplate code and unsubscribe your RxJS observables with ease - within your Angular components.

Getting started

1. npm i ngx-until-destroy
2. Decorate your component with @WithDestroy$()
3. Use .pipe(untilDestroy$(this)) before .subscribe(...)

And voilà, you don't have to take care of unsubscribing anymore. Your subscription exists as long as your component exists.

Example

@WithDestroy$()
@Component({...})
export class ExampleComponent {
  ...
  someObservable$.pipe(untilDestroy$(this)).subscribe(...)
}

How it works

What happens in the background is pretty simple.

@WithDestroy$() decorates your component in a way, that it will have a class variable named $destroy, it's a simple RxJS Subject, which emits a new value, when the component is destroyed - by extending ngOnDestroy().

untilDestroy$(this) is simply returning takeUntil(this.destroy$), so your subscription is going to be active just until your component is destroyed. No need for extra boilerplate code or unsubscribing manually.
