使用startWith时，RxJS跳过去抖动

Question

I have a stream that uses the startWith operator and debounceTime . I want the first value to skip the debounceTime and start immediately. How can I do it?

control.valueChanges
    .pipe(
      startWith(control.value), <=== this needs to skip debounce
      debounceTime(200),
      map(...),
    );

Answer 1

Just switch the order of operators and use startWith after debounceTime .

control.valueChanges.pipe(
  debounceTime(200),
  startWith(control.value),
  map(...),
);
