Installation

npm i --save @w11k/ngx-componentdestroyed@4.x.x

@Component({
  selector: 'foo',
  templateUrl: './foo.component.html'
})
export class FooComponent implements OnInit, OnDestroy {

  ngOnInit() {
    interval(1000)
        .pipe(
            untilComponentDestroyed(this)       // <--- 2. use the pipe operator
        )
        .subscribe();
  }

  ngOnDestroy() {                               // <--- 1. add empty stub
