is there an equivalent of async pipe that you can use inside a component?

Question

Does there exist something equivalent to the async pipe that I could use inside a component like this

   @Component({
      selector: \'my-component         


        

Answer 1

The only way you can your goal (not using subscription) is to use BehaviorSubject, it has a method getValue(). There are some differences between Observables and BehaviousSubjects (you can find them in documentation).

var subject = new Rx.BehaviorSubject(current_subject_value);
subject.getValue()

Yet there are some stackoverflow debates why shoudnd't you use getValue method, but rather to use subscription... Yet there is observable take operator which will complete observable sequence (thus don't have to manage subscriptions)

this.myObservable$.take(1).subscribe()
