Pause RxJS stream based on a value in the stream

Question

I have a simple component with a single button that starts and pauses a stream of numbers generated by RxJS timer.

import { Component, OnInit } from \'@angul         


        

Answer 1

As simple as it can get with one windowToggle and use active.next(false) working example: https://stackblitz.com/edit/angular-pdw7kw

 defer(() => {
      let count = 0;
      return stream$.pipe(
        windowToggle(on$, () => off$),
        exhaustMap(obs => obs),
        mergeMap(_ => {
          if ((++count) % 5 === 0) {
            this.active$.next(false)
            return never()
          }
          return of(count)
        }),
      )
    }).subscribe(console.log)
