Firebase Doesnt work! I suggest doing this inside authfile

[wann100]

    try {
      let user = await firebase.auth().createUserWithEmailAndPassword(email, password).then(function(data){
  console.log('uid',data.user.uid)
  firebase.database().ref(`/users/${data.user.uid}/userDetails`).set({
    email,
    phone,
    firstname,
    lastname,
    displayName
  });
  console.log('database has been put up')
  //Here if you want you can sign in the user
}).catch(function(error) {
    //Handle error
});
