You will also need to create a Firebase project. Follow the instructions on the Firebase website to create a new project and get your configuration information.

Once you have your configuration information, you can initialize Firebase in your app by adding the following code to your App.js file:

import firebase from 'react-native-firebase';

firebase.initializeApp({
  // Your Firebase configuration here
});

Usage

Once you have Firebase set up in your app, you can start using its features. Here are a few examples:

Authentication

To authenticate a user with email and password, you can use the following code:

import firebase from 'react-native-firebase';

firebase.auth().signInWithEmailAndPassword(email, password)
  .then(user => {
    // User signed in successfully
  })
  .catch(error => {
    // Error occurred
  });

Realtime Database

To read data from the Realtime Database, you can use the following code:

import firebase from 'react-native-firebase';

const ref = firebase.database().ref('path/to/data');

ref.once('value')
  .then(snapshot => {
    // Data read successfully
  })
  .catch(error => {
    // Error occurred
  });

Cloud Firestore

To read data from the Cloud Firestore, you can use the following code:

import firebase from 'react-native-firebase';

const docRef = firebase.firestore().collection('path/to/collection').doc('document');

docRef.get()
  .then(doc => {
    if (doc.exists) {
      // Document data retrieved successfully
    } else {
      // Document does not exist
    }
  })
  .catch(error => {
    // Error occurred
  });
