Usage

After creating a Firebase project and installing the library, you can then use it in your project by importing the library in your JavaScript code:

import firebase from 'react-native-firebase';

As the default app is pre-initialized natively there is no need to call initializeApp for the default app instance. Just import and go:

import firebase from 'react-native-firebase';

firebase.auth().signInAnonymously()
  .then((user) => {
    console.log(user.isAnonymous);
  });
