Realtime Database

Firebase Realtime Database allows you to store and sync data between your users in real-time. This is a NoSQL database that lets you build rich, collaborative applications by allowing secure access to the database directly from client-side code.

const { initializeApp } = require('firebase/app');
const { getDatabase, ref, set } = require('firebase/database');

// Initialize Firebase
const app = initializeApp({ /* your config */ });
const database = getDatabase(app);

// Write data to your database
set(ref(database, 'users/1'), {
  username: 'example',
  email: 'user@example.com'
});

Authentication

Firebase Authentication provides backend services to help authenticate users, including simple sign-in functionality as well as third-party providers like Google, Facebook, and Twitter.

const { initializeApp } = require('firebase/app');
const { getAuth, createUserWithEmailAndPassword } = require('firebase/auth');

// Initialize Firebase
const app = initializeApp({ /* your config */ });
const auth = getAuth(app);

// Create a new user
createUserWithEmailAndPassword(auth, 'user@example.com', 'password')
  .then((userCredential) => {
    // Signed in
    const user = userCredential.user;
    // ...
  })
  .catch((error) => {
    // Error handling
    const errorCode = error.code;
    const errorMessage = error.message;
    // ...
  });

Cloud Firestore

Cloud Firestore is a flexible, scalable database for mobile, web, and server development. It keeps your data in sync across client apps through real-time listeners and offers offline support.

const { initializeApp } = require('firebase/app');
const { getFirestore, collection, addDoc } = require('firebase/firestore');

// Initialize Firebase
const app = initializeApp({ /* your config */ });
const db = getFirestore(app);

// Add a new document with a generated id
addDoc(collection(db, 'users'), {
  first: 'Ada',
  last: 'Lovelace',
  born: 1815
});

Cloud Storage

Firebase Cloud Storage is built for app developers who need to store and serve user-generated content, such as photos or videos.

const { initializeApp } = require('firebase/app');
const { getStorage, ref, uploadBytes } = require('firebase/storage');

// Initialize Firebase
const app = initializeApp({ /* your config */ });
const storage = getStorage(app);

// Create a storage reference from our storage service
const storageRef = ref(storage, 'some-child');

// Upload file
uploadBytes(storageRef, file).then((snapshot) => {
  console.log('Uploaded a blob or file!');
});

Hosting

Firebase Hosting provides fast and secure hosting for your web app, static and dynamic content, and microservices.

const { initializeApp } = require('firebase/app');
const { getAuth } = require('firebase/auth');
const { getFirestore } = require('firebase/firestore');
const { getStorage } = require('firebase/storage');

// Initialize Firebase
// TODO: Replace the following with your app's Firebase project configuration
const firebaseConfig = {
  //...
};

const app = initializeApp(firebaseConfig);

// The rest of your web app's Firebase initialization and setup goes here...
// For example, you might set up Firebase Authentication, Firestore, and Storage as shown above.
