rxjs behavior subject set value from component

Question

I'm trying to achieve the following:

I have a service A, this service holds an rxjs behaviorsubject:

public publishedList:BehaviorSubject<Data> = new BehaviorSubject<Data>(null)

getlist():Observable<Data> {
return this.http.post(......).map((responseData) => {
 this.publishedList.next(responseData)
 this.publishedList.asObservable().share
 }
}

Component A listens to this behaviorsubject using subscribe in the constructor.
No issues here.

Now component B comes in to place and holds a button that should be able to clear or empty the publishedList in the service and Component A should be updated.

Is this possible? How do I achieve this?

Thanks

Answer 1

add this method to your service

setList(data:Data) {
  this.publishedList.next(data);
}

and call it from component B
