This might be a stupid question but I am learning all of this by myself and I didn't find anything about it in the documentation.

I am currently building a Vue app and using Firebase as my backend. In order to use the Firebase services, you create an app object with the initializeApp() method and then access services like the database by calling getDatabase(app) and working with the returned object. Now my question is: If I do these things inside my top level component (App), but then need to access the database inside another component, can I just call the getDatabase() method again, or do I have to somehow export the first object so that I can access it from other files?
