How do I detect if a user is already logged in Firebase?

I\'m using the firebase node api in my javascript files for Google login.

firebase.initializeApp(config);
let provider = new firebase.auth.GoogleAuthProvide

If you are allowing anonymous users as well as those logged in with email you can use firebase.auth().currentUser.isAnonymous, which will return either true or false.
