When should I use `publishReplay` vs `shareReplay`?

Question

I already know that

• publish shares a single subscription and also returns a ConnectableObservable ( so we have to Connect(

Answer 1

shareReplay() is basically publishReplay().refCount()

Definitely not.

Both shareReplay and publishReplay (+ calling connect on it) will make the observable behind it hot.

But the very important difference between them is:

• shareReplay: won't stop emitting until it's completed, no matter if there are no subscriptions anymore or not.
• publishReplay: will stop after the last subscriber unsubscribes if used together with refCount

Imho this is a crucial information.
