BehaviorSubject and ReplaySubject in Rxjs

 

  • BehaviorSubject

A variant of Subject that requires an initial value and emits its current value whenever it is subscribed to.

  • ReplaySubject

A variant of Subject that “replays” or emits old values to new subscribers. It buffers a set number of values and will emit those values immediately to any new subscribers in addition to emitting new values to existing subscribers.
