Join the chat at https://gitter.im/sahat/satellizer Build Status Test Coverage Version

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, Yahoo, Windows Live authentication providers, as well as Email and Password sign-in. 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

# NPM
npm install satellizer

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

<!--[if lte IE 9]>
    <script src="//cdnjs.cloudflare.com/ajax/libs/Base64/0.3.0/base64.min.js"></script>
<![endif]-->
<script src="//cdn.jsdelivr.net/satellizer/0.11.1/satellizer.min.js"></script>

Note: Sattelizer uses window.btoa and window.atob for parsing JWT. If you still have to support IE9, use the Base64 polyfill above.

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.yahoo({
      clientId: 'dj0yJmk9dkNGM0RTOHpOM0ZsJmQ9WVdrOVlVTm9hVk0wTkRRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0wMA--'
    });

    $authProvider.live({
      clientId: '000000004C12E68D'
    });

    $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>
<button ng-click="authenticate('yahoo')">Sign in with Yahoo</button>
<button ng-click="authenticate('live')">Sign in with Windows Live</button>

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

  authorizationEndpoint: null,
  responseParams: null,
  requiredUrlParams: null,
  optionalUrlParams: null,
  defaultUrlParams: ['response_type', 'client_id', 'redirect_uri'],
  responseType: 'code'
});

// OAuth 1.0
$authProvider.oauth1({
  url: null,
  name: null,
  popupOptions: null
});

Note: If for some reason you are unable to send a token to your server in the following format - Authorization: Bearer <token>, then use $authProvider.authHeader method to override this behavior, e.g. set its value to x-access-token or another custom header that your backend may require.

Not sending the JWT for specific requests

// This request will NOT send the token as it has skipAuthentication
$http({
  url: '/api/endpoint',
  skipAuthorization: true
  method: 'GET'
});

Updating storage

To toggle from localStorage and sessionStorage run $auth.setStorage('sessionStorage'); or $auth.setStorage('localStorage');

Browser Support

</tr>
<tr>
  <td align="center">9+</td>
  <td align="center">✓</td>
  <td align="center">✓</td>
  <td align="center">✓</td>
  <td align="center">✓</td>
</tr>

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.

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://apps.twitter.com](https://apps.twitter.com/) - Click on **Create New App** - Enter your *Application Name*, *Description* and *Website* - 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**

- Visit [Live Connect App Management](http://go.microsoft.com/fwlink/p/?LinkId=193157). - Click on **Create application** - Enter an *Application name*, then click on **I accept** button - Go to **API Settings** tab - Enter a *Redirect URL* - Click **Save** - Go to **App Settings** tab to get *Client ID* and *Client Secret*

Note: Microsoft does not consider localhost or 127.0.0.1 to be a valid URL. As a workaround for local development add 127.0.0.1 mylocalwebsite.net to /etc/hosts file and specify mylocalwebsite.net as your Redirect URL on API Settings tab.

API Reference

$auth.login(user)

Sign in via email and password where:

  • user - Plain JavaScript object.
Returns
  • response - The $http response object from the server.
$auth.login({
  email: $scope.email,
  password: $scope.password
});

Note: This method returns a promise.

$auth.signup(user)

Creates a local account with email and password. You can use whatever fields you want as long as you implement them on the server.

  • user - Plain JavaScript object.

Returns

  • response - The $http response object from the server.

Usage

$auth.signup({
  email: $scope.email,
  password: $scope.password
}).then(function(response) {
  console.log(response.data);
});

Note: This method returns a promise.

$auth.authenticate(name, [userData])

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

  • provider - One of the built-in provider names or a custom provider name created via $authProvider.oauth1() or $authProvider.oauth2() methods.
  • userData - Optional object for sending additional data to the server along with code, clientId, redirectUri (OAuth 2.0) or oauth_token, oauth_verifier (OAuth 1.0).

Returns

  • response - The $http response object from the server.

Usage

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

Note: This method returns a promise.

$auth.logout([redirect])

Deletes a JWT from Local Storage.

  • redirect - Optional URL string for redirecting after successful logout.

Usage

$auth.logout();

Note: This method returns a promise.

$auth.isAuthenticated()

Returns true if a JWT is present in Local Storage and it is not expired, otherwise returns false.

Note: This method expects the exp claim to check for the expiration time.

Usage

// 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 with the signed-in account. It is practically the same as $auth.authenticate() with the exception that it does not redirect to $authProvider.loginRedirect route path.

  • provider - One of the built-in provider names or a custom provider name created via $authProvider.oauth1() or $authProvider.oauth2() methods.
  • userData - Optional object for sending additional data to the server along with code, clientId, redirectUri (OAuth 2.0) or oauth_token, oauth_verifier (OAuth 1.0).

Note: Linking accounts business logic is handled entirely on the server.

Usage

$auth.link('github');

Note: This method returns a promise.

$auth.unlink(provider)

Unlinks an OAuth provider from the signed-in account. It sends a GET request to /auth/unlink/:provider.

  • provider - One of the built-in provider names or a custom provider name created via $authProvider.oauth1() or $authProvider.oauth2() methods.

Note: You can override the default unlink path above via $authProvider.unlinkUrl configuration property.

Note: It uses GET method by default, but can be changed via $authProvider.unlinkMethod = 'post'. If you are going to use POST, provider obviously should be an object, not a string.

Usage

$auth.unlink('github');

Note: This method returns a promise.

$auth.getToken()

Returns a JWT from Local Storage.

Usage

$auth.getToken();
// eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOjEyMzQ1Njc4OTAsIm5hbWUiOiJKb2huIERvZSJ9.kRkUHzvZMWXjgB4zkO3d6P1imkdp0ogebLuxnTCiYUU

$auth.getPayload()

Returns a JWT Claims Set, i.e. the middle part of a JSON Web Token.

Usage

$auth.getPayload();
// { exp: 1414978281, iat: 1413765081, sub: "544457a3eb129ee822a38fdd" }

$auth.setToken(token, [redirect])

Saves a JWT or an access token to Local Storage. It uses shared.setToken internally.

  • token - An object that takes a JWT (response.data[config.tokenName]) or an access token (response.access_token).
  • redirect - An optional boolean value that controls whether or not to redirect to loginRedirect route after saving a token. Defaults to false.

$auth.removeToken()

Removes a JWT from Local Storage.

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.
