Satellizer

👾 Live Demo: https://satellizer.herokuapp.com

Satellizer is a simple to use, end-to-end, token-based authentication module for AngularJS with built-in support for Google, Facebook, LinkedIn, Twitter authentication providers, plus Email and Password sign-in method. You are not limited to the sign-in options above, in fact you can add any OAuth 1.0 or OAuth 2.0 provider by passing provider-specific information during the configuration step.

Installation

The easiest way to get Satellizer is by running one of the following commands:

# Bower
bower install satellizer --save

# NPM
npm install satellizer --save

Note: Alternatively, you may download the latest release or use the CDN:

<script src="//cdn.jsdelivr.net/satellizer/0.7.0/satellizer.min.js"></script>

Usage

Step 1. App Module

angular.module('MyApp', ['satellizer'])
  .config(function($authProvider) {
    
    $authProvider.facebook({
      clientId: '624059410963642',
    });
    
    $authProvider.google({
      clientId: '631036554609-v5hm2amv4pvico3asfi97f54sc51ji4o.apps.googleusercontent.com'
    });
    
    $authProvider.github({
      clientId: '0ba2600b1dbdb756688b'
    });
    
    $authProvider.linkedin({
      clientId: '77cw786yignpzj'
    });

    $authProvider.twitter({
      url: '/auth/twitter'
    });

    $authProvider.oauth2({
      name: 'foursquare',
      url: '/auth/foursquare',
      redirectUri: window.location.origin,
      clientId: 'MTCEJ3NGW2PNNB31WOSBFDSAD4MTHYVAZ1UKIULXZ2CVFC2K',
      authorizationEndpoint: 'https://foursquare.com/oauth2/authenticate',
    });
    
  });

Step 2. Controller

angular.module('MyApp')
  .controller('LoginCtrl', function($scope, $auth) {
    
    $scope.authenticate = function(provider) {
      $auth.authenticate(provider);
    };
    
  });

Step 3. Template

<button ng-click="authenticate('facebook')">Sign in with Facebook</button>
<button ng-click="authenticate('google')">Sign in with Google</button>
<button ng-click="authenticate('github')">Sign in with GitHub</button>
<button ng-click="authenticate('linkedin')">Sign in with LinkedIn</button>
<button ng-click="authenticate('twitter')">Sign in with Twitter</button>
<button ng-click="authenticate('foursquare')">Sign in with Foursquare</button>

❗ Note: For server-side usage please refer to the examples directory.

❗ Note: If you stumble upon a browser version that does not work with Satellizer please open an issue so I could update the checkmark with the lowest supported version.

How It Works

Satellizer relies on token-based authentication using JSON Web Tokens instead of cookies. Each Wiki link below goes in-depth into how the authentication process works.

• Login with OAuth 2.0
• Login with OAuth 1.0
• Login with Email and Password
• Signup
• Logout

💡 Note: To learn more about JSON Web Token (JWT) visit JWT.io.

Obtaining OAuth Keys

- Visit [Google Cloud Console](https://cloud.google.com/console/project) - Click **CREATE PROJECT** button - Enter *Project Name*, then click **CREATE** - Then select *APIs & auth* from the sidebar and click on *Credentials* tab - Click **CREATE NEW CLIENT ID** button - **Application Type**: Web Application - **Authorized Javascript origins**: *http://localhost:3000* - **Authorized redirect URI**: *http://localhost:3000*

❗ Note: Make sure you have turned on Contacts API and Google+ API in the APIs tab.

---

- Visit [Facebook Developers](https://developers.facebook.com/) - Click **Apps > Create a New App** in the navigation bar - Enter *Display Name*, then choose a category, then click **Create app** - Click on *Settings* on the sidebar, then click **+ Add Platform** - Select **Website** - Enter *http://localhost:3000* for *Site URL*

---

- Sign in at [https://dev.twitter.com](https://dev.twitter.com/) - From the profile picture dropdown menu select **My Applications** - Click **Create a new application** - Enter your application name, website and description - For **Callback URL**: *http://127.0.0.1:3000* - Go to **Settings** tab - Under *Application Type* select **Read and Write** access - Check the box **Allow this application to be used to Sign in with Twitter** - Click **Update this Twitter's applications settings**

API Reference

• $auth.login(user)
• $auth.signup(user)
• $auth.authenticate(name, [userData])
• $auth.logout()
• $auth.isAuthenticated()
• $auth.link(provider, [userData])
• $auth.unlink(provider)

$auth.login(user)

Sign in via email and password where:

• user - data object with email and password properties.

$auth.login({
  email: $scope.email,
  password: $scope.password
});

$auth.signup(user)

Creates a new local account where:

• user - data object with email and password properties.

$auth.signup({
  email: $scope.email,
  password: $scope.password
});

$auth.authenticate(name, [userData])

Starts the OAuth 1.0 or OAuth 2.0 authentication flow by opening a popup where:

• name - one of the predefined provider names or a custom provider name created via $authProvider.oauth1() or $authProvider.oauth2().
• userData - optional object if you need to send some additional data to the server along with code, clientId and redirectUri in the case of OAuth 2.0 or oauth_token and oauth_verifier in the case of OAuth 1.0.

$auth.authenticate('google').then(function() {
  // Signed In.
});

$auth.logout()

Logs out current user by deleting the token from Local Storage.

$auth.logout();

$auth.isAuthenticated()

Returns true or false depending on if the user is signed in or not.

Controller:

$scope.isAuthenticated = function() {
  return $auth.isAuthenticated();
};

Template:

<ul class="nav navbar-nav pull-right" ng-if="!isAuthenticated()">
  <li><a href="/#/login">Login</a></li>
  <li><a href="/#/signup">Sign up</a></li>
</ul>
<ul class="nav navbar-nav pull-right" ng-if="isAuthenticated()">
  <li><a href="/#/logout">Logout</a></li>
</ul>

$auth.link(provider, [userData])

Links an OAuth provider to the account. Same as $auth.authenticate() with the exception that it does not redirect to $authProvider.loginRedirect path.

• provider - one of the predefined provider names or a custom provider name created via $authProvider.oauth1() or $authProvider.oauth2().
• userData - optional object if you need to send some additional data to the server along with code, clientId and redirectUri in the case of OAuth 2.0 or oauth_token and oauth_verifier in the case of OAuth 1.0.

💡 Note: Account linking business logic is handled entirely on the server.

$auth.link('github');

$auth.unlink(provider)

Unlinks an OAuth provider from the account by sending a GET request to the /auth/unlink/ URL.

$auth.unlink('github');

Contributing

Found a typo or a bug? Send a pull request. I would especially appreciate pull requests for server-side examples since I do not have much experience with any of the languages on the TODO list.

Credits

A big thanks goes to Alice Chen for all your hard work on the Dropwizard implementation and Jesús Rodríguez for being so proactive and actively reporting bugs.

Additionally, I would like to thank all other contributors who have submitted issues and/or pull requests!

Satellizer was inspired by ng-token-auth and torii and angular-oauth.
