Auth0 Ember simple auth

An ember-cli addon for using Auth0 with Ember Simple Auth.

Auth0's lock widget, is a nice way to get a fully functional signup and login workflow into your app.

What does it do?

  • it wires up Auth0's Lock.js to work with ember simple auth.
  • it lets you work with ember simple auth just like you normally do!

Installation and Setup

Auth0

If you don't already have an account, go signup at for free: Auth0

  1. Create a new app through your dashboard.
  2. Done!

Generate a new ember app and install auth0-ember-simple-auth using ember-cli (Ember CLI >= 0.2.7)

ember new hello-safe-world
cd hello-safe-world
ember install auth0-ember-simple-auth

If you want to get up and running right away, you can scaffold all the necessary routes with to play with:

ember generate scaffold-auth0

Configuration

There are two configuration options.

  1. (REQUIRED) - clientID - Grab from your Auth0 Dashboard
  2. (REQUIRED) - domain - Grab from your Auth0 Dashboard

The below simple-auth config object works out the box with the scaffold

// config/environment.js
ENV['simple-auth'] = {
  authorizer: 'simple-auth-authorizer:jwt',
  authenticationRoute: 'index',
  routeAfterAuthentication: 'protected',
  routeIfAlreadyAuthenticated: 'protected'
}
 
ENV['auth0-ember-simple-auth'] = {
  clientID: "auth0_client_id",
  domain: "auth0_domain"
}

At this point if you ran scaffold-auth0, you can fire up ember server:

ember server --port

The below steps will outline the steps to get up and running with the scaffolding:

Suggested security config

Ember uses a content security policy to manage which resources are allowed to be run on your pages.

// config/environment.js
 
ENV['contentSecurityPolicy'] = {
    'font-src': "'self' data: https://*.auth0.com",
    'style-src': "'self' 'unsafe-inline'",
    'script-src': "'self' 'unsafe-eval' https://*.auth0.com",
    'img-src': '*.gravatar.com *.wp.com data:',
    'connect-src': "'self' http://localhost:* https://your-app-domain.auth0.com"
  };
 

Caveats

  1. Because ember simple auth listens for local storage changes, updates in one tab will trigger token refreshes in all open tabs of the same domain. This is not critical for long lived JWTs but will be noticeable if there are several tabs of the app running on the same browser with very short lived JWTs. I'm open to suggestions on getting around this.

Manual Setup

auth0-ember-simple-auth is just a regular authenticator that conforms to the Ember Simple Auth interface. Please follow the docs to get everything working as usual, and just add the call to the simple-auth-authenticator:lock authenticator in your authenticate call.

Actions

Once the standard Ember Simple Auth application_route_mixin is added to your app route, you will be able to use all the usual actions: Docs

Here is an example application route:

// app/routes/application.js
 
import Ember from 'ember';
import ApplicationRouteMixin from 'simple-auth/mixins/application-route-mixin';
 
export default Ember.Route.extend(ApplicationRouteMixin, {
  actions: {
    sessionRequiresAuthentication: function(){
      // Check out the docs for all the options:
      // https://auth0.com/docs/libraries/lock/customization
 
      // These options will request a refresh token and launch lock.js in popup mode by default
      var lockOptions = {authParams:{scope: 'openid'}};
 
      this.get('session').authenticate('simple-auth-authenticator:lock', lockOptions);
    }
  }
});

Then from your template you could trigger the usual actions:

// app/templates/application.hbs
 
{{#if session.isAuthenticated}}
  <a {{ action 'invalidateSession' }}>Logout</a>
{{else}}
  <a {{ action 'sessionRequiresAuthentication' }}>Login</a>
{{/if}}

Custom Authenticators

You can easily extend the Auth0EmberSimpleAuth base authenticator to play hooky with some cool hooks.

Here's how:

ember generate authenticator my-cool-authenticator

This will create the following stub authenticator:

// app/authenticators/my-cool-authenticator.js
 
import Base from 'auth0-ember-simple-auth/authenticators/lock';
 
export default Base.extend({
 
  /**
   * Hook that gets called after the jwt has expired
   * but before we notify the rest of the system.
   * Great place to add cleanup to expire any third-party
   * tokens or other cleanup.
   *
   * IMPORTANT: You must return a promise, else logout
   * will not continue.
   *
   * @return {Promise} 
   */
  beforeExpire: function(){
    return Ember.RSVP.resolve();
  },
 
  /**
   * Hook that gets called after Auth0 successfully
   * authenticates the user.
   * Great place to make additional calls to other
   * services, custom db, firebase, etc. then
   * decorate the session object and pass it along.
   *
   * IMPORTANT: You must return a promise with the
   * session data.
   *
   * @param  {Object} data Session object
   * @return {Promise}     Promise with decorated session object
   */
  afterAuth: function(data){
    return Ember.RSVP.resolve(data);
  },
 
  /**
   * Hook called after auth0 refreshes the jwt
   * based on the refreshToken.
   *
   * This only fires if lock.js was passed in
   * the offline_mode scope params
   *
   * IMPORTANT: You must return a promise with the
   * session data.
   *
   * @param  {Object} data The new jwt
   * @return {Promise}     The decorated session object
   */
  afterRestore: function(data){
    return Ember.RSVP.resolve(data);
  },
 
  /**
   * Hook that gets called after Auth0 successfully
   * refreshes the jwt if (refresh token is enabled).
   *
   * Great place to make additional calls to other
   * services, custom db, firebase, etc. then
   * decorate the session object and pass it along.
   *
   * IMPORTANT: You must return a promise with the
   * session data.
   *
   * @param  {Object} data Session object
   * @return {Promise}     Promise with decorated session object
   */
  afterRefresh: function(data){
    return Ember.RSVP.resolve(data);
  }
 
});
 

Once you've made your custom authenticator. Just do the following in your app route:

import Ember from 'ember';
import ApplicationRouteMixin from 'simple-auth/mixins/application-route-mixin';
 
export default Ember.Route.extend(ApplicationRouteMixin, {
  actions: {
    sessionRequiresAuthentication: function(){
      // Check out the docs for all the options:
      // https://auth0.com/docs/libraries/lock/customization
 
      var lockOptions = {authParams:{scope: 'openid'}};
      this.get('session').authenticate('authenticator:my-cool-authenticator', lockOptions);
    }
  }
});
 

Custom Authorizers

You can easily extend the EmberSimpleAuth base authorizer to create custom authorization logic.

Here's how:

ember generate authorizer my-cool-authorizer

This will generate the following authorizer.

// app/authorizers/my-cool-authorizer.js
 
import Ember from 'ember';
import Base from 'simple-auth/authorizers/base';
 
export default Base.extend({
  authorize: function(jqXHR, requestOptions) {
 
    var secureData = this.get('session.secure');
 
    if (this.get('session.isAuthenticated') && !Ember.isEmpty(secureData.jwt)) {
      // Set request headers here.
      // secureData.jwt is the jwt from Auth0.
      // 
      // jqXHR.setRequestHeader('Authorization', 'Bearer ' + secureData.jwt);
 
    }
 
  }
});
 

To use the new authorizer, just update your config as follows:

// config/environment.js
ENV['simple-auth'] = {
  ...
  authorizer: 'authorizer:my-cool-authorizer',
  ...
}
 

Remember, you will also need to update your crossOriginWhitelist if you are making cross domain requests. If not, ember simple auth will not trigger the authorizer's authorize method.
