RxJS - .subscribe() vs .publish().connect()

Question

This is mainly an RxJs best practice/approach question, since my POC code works but I\'m brand new to RxJs.

The question boils down to .subscribe() vs <

Answer 1

This sidesteps your question a bit but you may find it helpful:

I would not return a different observable stream from the one that calls the http service because doing so makes it impossible for the calling function to:

• cancel the stream
• modify the stream
• determine whether the operation was successful

Instead I'd do:

auth.servive.ts

logout() : Observable  {
       return this.http.get(...).map(this.extractData)          
            .catch(this.handleError);
}

Now the calling code can do whatever it wants with the resulting url

logout.component.ts

logout(){
    this.authService.logout().subscribe(
        url => window.location.href = url,
        err => {
            /*todo: handle if error was thrown by authService.handleError*/
        }
    );
}
