RxJS 6 – Cancel / End a Pipe
You can also cancel/end a pipe by using a signal Subject and the rxjs operator: takeUntil Example httpGetSafe(path: string): Observable<Data> { const stopSignal$ = new Subject(); return this.http.get<Data>(path).pipe( map(data => { const isBad = data === null; if (isBad) { stopSignal$.next(); } return data; }), takeUntil(stopSignal$) ); } Sometimes it’s a bit simpler and more … Read more
