Firebase stop listening onAuthStateChanged

Question

As of version ^3.0.0, I\'m having a difficult time removing the auth state change listener.

To start the listener per the documentation:

firebase.a         


        

Answer 1

According to the documentation, the onAuthStateChanged() function returns

The unsubscribe function for the observer.

So you can just:

var unsubscribe = firebase.auth().onAuthStateChanged(function (user) {
    // handle it
});

And then:

unsubscribe();
