Observable forkJoin not firing

Question

I\'m trying to user forkJoin on two Observables. One of them starts as a stream... If I subscribe to them directly I get a response, forkJoin isn\'

Answer 1

forkJoin emits only when all inner observables have completed. If you need an equivalent of forkJoin that just listens to a single emission from each source, use combineLatest + take(1)

combineLatest(
  this.statuses$,
  this.companies$,
)
.pipe(
  take(1),
)
.subscribe(([statuses, companies]) => {
  console.log('forkjoin');
  this._countStatus(statuses, companies);
});

As soon as both sources emit, combineLatest will emit and take(1) will unsubscribe immediately after that.
