EmberJS add-on for blueprint-gatekeeper

• Ember.js v4.4 or above
• Ember CLI v4.4 or above
• Node.js v14 or above

ember install ember-cli-gatekeeper

Update the ENV variable in config/environment.js with the required configuration values:

The client secret should only be used if the web application is installed in a trusted environment, such as a mobile application via ember-cordova.

Here is an example config/environment.js with the Gatekeeper configuration:

let ENV = {
  // ...
  
  EmberENV: {
    FEATURES: {
    // This must be enabled for account adapter to work.
    'ds-improved-ajax': true
    }
    
    // ...
  },
  
  gatekeeper: {
    baseUrl: 'https://mydomain.com/gatekeeper',

    tokenOptions: {      
      client_id: '59ee923e1fd71c2ae68ade62',
      client_secret: '1234567890'
    }
  }
}

Protected application routes are routes that require the user to be signed in to access. Creating protected application route is very simple.

First, create the route using ember-cli.

ember g route [name]

Then, import the authenticated decorator from ember-cli-gatekeeper and apply it to the route.

// app/routes/comments.js

import Route from '@ember/routing/route';
import { authenticated } from 'ember-cli-gatekeeper';

@authenticated
export default class CommentsRoute extends Route {
  async model () {
    // Get all comments for the current user.
    return this.store.query ('comment', { user: this.session.currentUser.id });
  }
};

The session service is injected into all routes. This service can be used to access the currentUser property, which gives you access to the account model (less the password) for the signed in user.

When this route is accessed and the user is not signed in, the user will be transitioned to the sign-in route (see Configuration). After the user signs in, the user will be transitioned back to the original route.

ember-data uses data models to access resources on a remote server. When using Gatekeeper, the routes for accessing these resources is protected via an authorization token. To get this authorization token into each ember-data request, you must use the @bearer decorator.

// app/adapters/application.js
import RESTAdapter from "@ember-data/adapter/rest";
import {bearer} from 'ember-cli-gatekeeper';

@bearer
export default class ApplicationAdapter extends RESTAdapter {
  
}

You can then continue configuring the adapter as normal.

To sign in a user, you need a route with a form that collects the user's username and password. The Gatekeeper add-on provides a component/form that can be used to sign-in a user.

<GatekeeperSignIn />

This component needs to be added to your sign-in route. When the user has signed in successfully, the component will automatically route the user to either the start route defined in the configuration, or the route originally accessed when the user was not authenticated.

Gatekeeper uses different public/private key verification schemes to ensure that robots are not accessing the system. When developing a web application, it is not save to place a secret in an EmberJS application because it will be accessible to site visitors. We therefore recommend you use a reCAPTCHA service, such as Google reCAPTCHA, to verify users are not robots.

Gatekeeper provides out-of-the-box support for Google reCAPTCHA via the ember-cli-google-recaptcha add-on. First, you have to do is add your siteKey to config/environment.js:

let ENV = {
  // ...
  
  'ember-cli-google': {
    recaptcha: {
      siteKey: 'This is where my siteKey goes'
    }
  }
};

The add-on will automatically detect the presence of the siteKey, and enable Google reCAPTCHA in the default login form. Next, you replace the standard sign in component with the reCAPTCHA sign in component.

<GatekeeperSignInWithRecaptcha recaptcha="v2" />

Set recaptcha="invisible" to use invisible reCAPTCHA.

A signed in user can be signed out from any where in the application as long as you have access to the session service.

The session service is injected into all routes and controllers.

// app/controllers/index.js

import Controller from '@ember/controller';
import { action } from '@ember/object';

export default class IndexController extends Controller {
  @action
  async signOut () {
    await this.session.signOut ();
    this.replaceRoute ('sign-in');
  }
}

The Gatekeeper add-on also provides a default form for creating a new account. You use it in a similar manner as signing in a user. First, add the sign up form to the route for signing up a user, and configure the form to your needs.

<GatekeeperSignUp />

The Gatekeeper add-on also has sign up components that supports reCAPTCHA.

The client registered with the server must have the gatekeeper.account.create scope. Otherwise, the client will not be authorized to create the account.

We use the account model to create user accounts. We assume that you have created a template to gather the username, password, and email address from the user and have a controller action to that creates the account:

import Controller from '@ember/controller';
import { action } from '@ember/object';

export default class SignUpController extends Controller {
  @action
  async createAccount () {
    const account = this.store.createRecord ('account', {username: this.username, password: this.password, email: this.email});
    const adapterOptions = {signIn: true};
      
    await account.save ({adapterOptions});

    // You can transition to a protected application route
  }
}

The save() method takes an optional adapterOptions property that allows you to sign in the user when the account is created. The advantage of doing this it that it allows you to transition to a protected application route after account creation, or access protected data as part of the creation process. Otherwise, the user will have to sign in after creating the account to access a protected application route.

Happy Coding!
