    backoff-rxjs

    A collection of helpful RxJS operators to deal with backoff strategies (like exponential backoff) Angular-in-Depth article about this library is at https://blog.angularindepth.com/power-of-rxjs-when-using-exponential-backoff-a4b8bde276b0

    intervalBackoff

    Basic interval backoff

    intervalBackoff works similiarly to interval except that it doubles the delay between emissions every time.

    name type attirbute description
    config number | IntervalBackoffConfig required Can take number as initial interval or a config with initial interval, optional max Interval and optional backoff delay function (exponential by default)

    interval is especially useful for periodic polls that are reset whenever user activity is detected:

    fromEvent(document, 'mousemove').pipe(
      // There could be many mousemoves, we'd want to sample only
      // with certain frequency
      sampleTime(LOAD_INTERVAL_MS),
     
      // Start immediately
      startWith(null),
     
      // Resetting exponential interval
      switchMapTo(
        intervalBackoff({
          initialInterval: LOAD_INTERVAL_MS,
          maxInterval: MAX_INTERVAL_MS
        })
      )
    );

    name type attirbute description
    config number | RetryBackoffConfig required Can take number as initial interval or a config with initial interval, optional max Interval, optional max number of retry attempts, optional function to cancel reties and optional backoff delay function (exponential by default)
