Firebase: No Firebase App '[DEFAULT]' has been created Error

vanbumi · July 11, 2017, 2:12am

Anyone has experience this error?

When I tried to login with firebase auth with email & password.

Firebase: No Firebase App ‘[DEFAULT]’ has been created - call Firebase App.initializeApp() (app/no-app).

Hi welcome to Expo @vanbumi!

A couple of questions

Are you importing Firebase?
Have you called firebase.initializeApp?

vanbumi · July 16, 2017, 1:00pm

yes I have done this:

componetWillMount() {
const config = {
apiKey: “xxxxxxxxxxxxxxxxxxxxxxxx”,
authDomain: “auth-bdcdc.firebaseapp.com”,
databaseURL: “https://auth-bdcdc.firebaseio.com”,
projectId: “auth-bdcdc”,
storageBucket: “auth-bdcdc.appspot.com”,
messagingSenderId: “xxxxxxxxxx”
};
firebase.initializeApp(firebaseConfig);

Change componetWillMount ==to==> componentWillMount

this is a little mistake

vanbumi · July 17, 2017, 3:04am

Oww my… !!

typo

thanks sms1989, you save me

michaelstokes · March 14, 2018, 12:36pm

Thanks @sms1989 Great prompt! For whatever reason I was using componentDidMount so it was never going to happen …

I’m calling the firebase initialize app in my main App.js and then having a Loading Screen which is the initial route I’m then checking whether the user is signed in or not

    componentDidMount() {
        firebase.auth().onAuthStateChanged(function(user) {
            if (user) {
                console.log('User is signed in.');
            } else {
                // No user is signed in.
                console.log('No user is signed in.');
            }
        });
    }

Whether I should do this in saga or not, I’m not quite sure yet.

Thanks anyway!
