RxjS shareReplay : how to reset its value?

Question

I use shareReplay to call only once (like a cache) a webservice to retrieve some informations :

In my service :

getProf         


        

Answer 1

Thanks to the answer of martin (which didn't work for me) I found a way to do it :

protected profile: Observable;
private refresh$ = new Subject();

constructor() {
    this.profile = this.refresh$.pipe(shareReplay(1));

    this.resetProfile();
}


getProfile(): Observable {
    return this.profile;
}

resetProfile() {
    this.callWS().subscribe(user => {
        this.refresh$.next(user);
    });
}

I think there is maybe something better/cleaner to do (using a Behavior Subject ?), so if you know something better ..
