Angular: How to inject a service from a different module

Question

I have two Modules (A,B) which are used in the App.

• A has a service with functions (A.service.a(), A.service.b()).
• B needs a service like A.service but only needs function a(). Because of this, in module B I wrote a class definition for this service with only the function a().

Now I want to inject the A.service in the App into the module B. But because - I guess - the classes of the Service are different it woudn't find the the service to inject.
So is it possible to inject services which are not in the same service class but implement the right functionality?
Or is this the wrong way?

Answer 1

You just need to register these services in the modules you want to use in by passing them in providers array.

Here is the stackblitz demo on how to do that:- https://stackblitz.com/edit/angular-ud7bjh?file=src%2Fapp%2Fapp.component.ts
