Expo: “auth/operation-not-supported-in-this-enviroment”

Question

I develop a react-native (expo) mobile app and try to sign in with a google account to firebase, but I get an error:

\"auth/operation-not-supported-in

Answer 1

signInWithPopup is not supported in react-native. You will need to use a third party OAuth library to get the OAuth ID token or access token and then sign in with Firebase:

const cred = firebase.auth.GoogleAuthProvider.credential(googleIdToken, googleAccessToken);
firebase.auth().signInWithCredential(cred)
  .then((result) => {
    // User signed in.
  })
  .catch((error) => {
    // Error occurred.
  });
