How to pass an action from a service to a component?

Question

Angular

Good afternoon!
Yesterday asked the question How to use a function inside a function inside a class?
And I ran into a new problem. How to tell the component that the song is over? Is it possible to somehow pass data from the service to the component?

Answer 1

Yes, you can use pubsub to send events, or add a listener to the service and the component will already subscribe to it.
