Grape-Doorkeeper

Create an awesome versioned API, secured with OAuth2 and automatically documented.

This is a basic Rails 4 application with Doorkeeper, Grape & Swagger for getting to API building quickly.

You can view the live app and the Swagger-ui documentation.

This app is ready to deploy to Heroku

Set up

First bundle install and rake db:setup

Run rake start to get the server running locally. It runs at http://localhost:3001

You will want to change config/initializers/secret_token.rb and export DEVISE_SECRET_KEY (see config/initializers/devise.rb).

You will also probably want to delete the imaginary item class and serializer, which are included for demonstration in the me/items endpoint.

This app includes omniauth-bike-index. For Bike Index login to work, export environment variables BIKEINDEX_APP_ID and BIKEINDEX_APP_SECRET. You'll need a Bike Index app, which you can create at BikeIndex.org/oauth/applications/new.

Bike Index uses a similar grape, Swagger, doorkeeper setup—this is an example of creating an OmniAuth strategy for doorkeeper.

Notes

Grape is mounted in app/controllers/api, as described in the excellent Introduction to building APIs with Grape by Monterail, and part 2 of the series.

There are are other posts in the series which are worth reading, particularly OAuth Implicit Grant with Grape, Doorkeeper and AngularJS.

There is also a Railscast on doorkeeper.

Important things in the Gemfile:

• Doorkeeper (OAuth providing)
• grape (API building)
• wine_bouncer (Doorkeeper and Grape)
• grape-swagger (automatically generates Swagger docs for the auto documentation)
• Devise (users)

Also important, but maybe not as necessary to know about:

• rails_swagger-ui (how we get swagger-ui)
• Puma (the web server)
• api-pagination
• grape-active_model_serializers
• CORS
• foreman (in development to manage processes)
• Haml
• dotenv-rails (load environmental variables - .env is in .gitignore, so it isn't committed)
• Bootstrap
• Postgres

---

If you want to change the name of the app, swap out:

• GrapeDoorkeeper in config/application.rb
• grape-doorkeeper in config/database.yml (multiple instances)
• grape-doorkeeper in config/initializers/session_store.rb

Testing

Rspec and guard - run bundle exec guard to watch your spec files for changes and rerun tests for those files.

There is a spec for the api/v1/me API route and for the swagger docs to help get you started.
