getHttpDistinctResponse.ts

  public getHttpDistinctResponse(httpRequest$: Observable<any>): Observable<any> {
    let cachedResponseStr = null;
    return httpRequest$.pipe(
      filter((response) => {
        const currentResponseStr = JSON.stringify(response);
        const areEquals = cachedResponseStr === currentResponseStr;
        if (!areEquals) {
          cachedResponseStr = currentResponseStr;
        }
        return !areEquals;
      })
    );
  }

export function pollingOnResolved(httpRequest$: Observable<any>, delayMs = 0): Observable<any> {
  const polling$ = new BehaviorSubject({});
  const rePolling$ = 
    of('').pipe(
    delay(delayMs),
    tap(() => polling$.next({})),
    skip(1)
  );
  // BOOM
  const request = ignoreEqualResponses ? this.getHttpDistinctResponse(httpRequest$) : httpRequest$;
  const httpPolling$ = concat(request, rePolling$);
  return polling$.pipe(switchMap(() => httpPolling$));
}
     

disagree on something that is testable, and easy to confirm is ignorance, anyway...
You said the best; you have a good weekend too. ✌️
