All the Loopback packages are updated to the latest version to contain the security fixes.

Templates

There are two email templates for user verification and password reset. These are customizeable EJS files (verify.ejs and reset.ejs) located in /api/template. They are used by verify.js and reset.js located in /api/models/user. You may send custom fields to your EJS files by adding them to options in verify.js and ejs.render() in reset.js.

Tests

Module tests are defined using a test/scenarios.yaml file. This file defines the set of example gigs that we generate as part of integration testing. To run all tests, run yarn test at the root of this module.

Each scenario is generated in test/scenario/<name> which you can then cd into and run the actual app. For a scenario called default, this is done via:

cd test/scenario/default
yarn install

# Run tests.
yarn test

# Start the app.
yarn start

Generation

Models

The module ntributes the following models to the project.

The following configuration are added to the Loopback config.json:

• emailSender
• verifyEmailSubject
• resetEmailSubject

Scenario

Facebook auhtentication

1. Configure gig.yaml to setup Facebook authentication

  - name: loopback-authentication
    location: >-
      https://github.com/liquidlabs-co/gig-modules/tree/master/block/loopback-authentication
    spec:
      generateTests: true
      webEnabled: true
      defaultDatasource: fileDs
      defaultEmailDatasource: email
      emailVerificationRequired: false
      emailSender: no-reply@example.com
      verifyEmailSubject: Thanks for Registering
      resetEmailSubject: Password Reset
      providers:
        local: {}
        facebook-login:
          clientID: FACEBOOK_CLIENT_ID
          clientSecret: FACEBOOK_CLIENT_SECRET

2. Create an application on Facebook

• Navigate to Facebook App Management
• Add a new application, for example gdt-test
• Select to set up the Facebook Login product
• Select web for the authentication
• Enter http://localhost:3000 for the site URL

We are done with the Facebook application tutorial to add an application and set up a product.

• Under Products > Facebook Login > Settings, set the valid OAuth redirect URIs to http://localhost:3000 and save changes
• Under dashboard, you shoud now have your App ID and App Secret, they map to FACEBOOK_CLIENT_ID and FACEBOOK_CLIENT_SECRET environment variables respectively.

Now we can generate nd then test the api

• Generate the project
• In the api folder, install the application and then start it passing the emvironment variables, something like DEBUG=gdt:loopback:authentication FACEBOOK_CLIENT_ID=******* FACEBOOK_CLIENT_SECRET=******* npm start
• Navigate to http://localhost:3000/auth/facebook and accept to link the application

You should get a json containing the access token. You can now use the access token to connect to the API endpoint using its value in an Authorization header.

Troubleshooting

DEBUG=gdt:loopback:authentication npm start
