Firebase - App success made simple


Firebase provides the tools and infrastructure you need to develop, grow, and earn money from your app. This package supports web (browser), mobile-web, and server (Node.js) clients.

Get the code (browser)

Script include

Include Firebase in your web application via a <script> tag:

<script src="https://www.gstatic.com/firebasejs/3.3.1/firebase.js"></script>

  var app = firebase.initializeApp({
    apiKey: '<your-api-key>',
    authDomain: '<your-auth-domain>',
    databaseURL: '<your-database-url>',
    storageBucket: '<your-storage-bucket>'
  // ...

Note: To get a filled in version of the above code snippet, go to the Firebase console for your app and click on "Add Firebase to your web app".

npm bundler (Browserify, Webpack, etc.)

The Firebase JavaScript npm module contains both a browser version and a version for the Node.js runtime. The browser version is designed to be used with a package bundler (e.g., Browserify, Webpack).

Install the Firebase npm module:

$ npm init
$ npm install --save firebase

In your code, you can access Firebase using:

var firebase = require('firebase');
var app = firebase.initializeApp({ ... });
// ...

Include only the features you need

The full Firebase JavaScript client includes support for Firebase Authentication, the Firebase Realtime Database, and Firebase Storage. Including code via the above snippets will pull in all of these features.

You can reduce the amount of code your app uses by just including the features you need. The individually installable components are:

  • firebase-app - The core firebase client (required).
  • firebase-auth - Firebase Authentication (optional).
  • firebase-database - The Firebase Realtime Database (optional).
  • firebase-storage - Firebase Storage (optional).

From the CDN, include the individual components you need (include firebase-app first):

<script src="https://www.gstatic.com/firebasejs/3.3.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/3.3.1/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/3.3.1/firebase-database.js"></script>
<script src="https://www.gstatic.com/firebasejs/3.3.1/firebase-storage.js"></script>

  var app = firebase.initializeApp({ ... });
  // ...

When using this npm package, just require() the components that you use:

var firebase = require('firebase/app');

var app = firebase.initializeApp({ ... });
// ...

Get the code (Node.js - server and command line)


While you can write entire Firebase applications without any backend code, many developers want to write server applications or command-line utilities using the Node.js JavaScript runtime.

You can use the same npm module to use Firebase in the Node.js runtime (on a server or running from the command line):

$ npm init
$ npm install --save firebase

In your code, you can access Firebase using:

var firebase = require('firebase');
var app = firebase.initializeApp({ ... });
// ...

Firebase Storage is not included in the server side Firebase npm module. Instead, you can use the gcloud Node.js client.

$ npm install --save gcloud

In your code, you can access your Storage bucket using:

var gcloud = require('gcloud')({ ... });
var gcs = gcloud.storage();
var bucket = gcs.bucket('<your-firebase-storage-bucket>');

API definition

If you use the Closure Compiler or compatable IDE, you can find API definitions for all the Firebase JavaScript API in the included /externs directory in this package:
