What are @react-native-firebase/app's main functionalities?

Initialize Firebase

This code initializes the Firebase app with the provided configuration. It checks if any Firebase app instances already exist to avoid re-initialization.

import firebase from '@react-native-firebase/app';

const firebaseConfig = {
  apiKey: 'your-api-key',
  authDomain: 'your-auth-domain',
  projectId: 'your-project-id',
  storageBucket: 'your-storage-bucket',
  messagingSenderId: 'your-messaging-sender-id',
  appId: 'your-app-id',
};

if (!firebase.apps.length) {
  firebase.initializeApp(firebaseConfig);
}

Access Firebase Services

This code demonstrates how to access Firebase services like Authentication and Firestore. It includes examples of signing in a user and fetching data from a Firestore collection.

import auth from '@react-native-firebase/auth';
import firestore from '@react-native-firebase/firestore';

// Example: Using Firebase Authentication
const signIn = async (email, password) => {
  try {
    await auth().signInWithEmailAndPassword(email, password);
    console.log('User signed in!');
  } catch (error) {
    console.error(error);
  }
};

// Example: Using Firestore
const getUsers = async () => {
  const usersCollection = await firestore().collection('Users').get();
  usersCollection.forEach(documentSnapshot => {
    console.log('User ID: ', documentSnapshot.id, documentSnapshot.data());
  });
};
