Looking for a RxJS operator alternative to set/clearTimeout in these circumstances:
this.mouseEnterSubscription = this.mouseEnterStream
.subscribe(() => {
this.timeout = setTimeout(() => {
void this.playVideo();
}, 500)
});
this.mouseLeaveSubscription = this.mouseLeaveStream.subscribe(() => {
this.pauseVideo();
clearTimeout(this.timeout);
});
Utilize debounceTime to postpone emission until a specified time has elapsed without receiving a new emission, and employ takeUntil to conclude an observable when another observable emits a value:
const mouseEnterSubscription = mouseEnterStream.pipe(
debounceTime(500),
takeUntil(mouseLeaveStream),
repeat(),
).subscribe(
() => playVideo()
);
In this code snippet, we delay emitting for 500ms but will exit if the mouseLeaveStream emits first. The use of takeUntil ensures that your mouseLeaveSubscription does not need to handle any cleanup tasks. We utilize repeat to "restart" the completed source (otherwise it would only emit once).
const mouseLeaveSubscription = mouseLeaveStream.subscribe(
() => pauseVideo()
);
For reference, here is a StackBlitz example.
