Closed ersimont closed 1 year ago

ersimont commented 1 year ago

Extract it from keepWakeLock$()

export function pageIsVisible$(): Observable<boolean> {
  return fromEvent(document, 'visibilitychange').pipe(
    startWith(undefined),
    map(() => document.visibilityState === 'visible'),
    distinctUntilChanged(),
  );
}
