The devise-api gem is a convenient way to add authentication to your Ruby on Rails application using the devise gem. It provides support for access tokens and refresh tokens, which allow you to authenticate API requests and keep the user's session active for a longer period of time on the client side. It can be installed by adding the gem to your Gemfile, running migrations, and adding the :api module to your devise model. The gem is fully configurable, allowing you to set things like token expiration times and token generators.

Devise API

The devise-api gem is a convenient way to add authentication to your Ruby on Rails application using the devise gem. It provides support for access tokens and refresh tokens, which allow you to authenticate API requests and keep the user's session active for a longer period of time on the client side. It can be installed by adding the gem to your Gemfile, running migrations, and adding the :api module to your devise model. The gem is fully configurable, allowing you to set things like token expiration times and token generators.

Here's how it works:

  • When a user logs in to your Rails application, the devise-api gem generates an access token and a refresh token.
  • The access token is included in the API request headers and is used to authenticate the user on each subsequent request.
  • The refresh token is stored on the client side (e.g. in a browser cookie or on a mobile device) and is used to obtain a new access token when the original access token expires.
  • This allows the user to remain logged in and make API requests without having to constantly re-enter their login credentials.

Overall, the devise-api gem is a useful tool for adding secure authentication to your Ruby on Rails application.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add devise-api

Or add the following line to the application's Gemfile:

gem 'devise-api', github: 'nejdetkadir/devise-api', branch: 'main'

If bundler is not being used to manage dependencies, install the gem by executing:

gem install devise-api

After that, you need to generate relevant migrations and locales by executing:

$ rails generate devise_api:install

This will introduce two changes:

  • Locale files in config/locales/devise_api.en.yml
  • Migration file in db/migrate to create devise api tokens table

Now you're ready to run the migrations:

$ rails db:migrate

Finally, you need to add :api module to your devise model. For example:

class User < ApplicationRecord
  devise :database_authenticatable, 
         :registerable, 
         :recoverable,
         :rememberable,
         :validatable,
         :api # <--- Add this module
end

Your user model is now ready to use devise-api gem. It will draw routes for token authenticatable and token refreshable.

Prefix Verb URI Pattern Controller#Action
revoke_user_tokens POST /users/tokens/revoke devise/api/tokens#revoke
refresh_user_tokens POST /users/tokens/refresh devise/api/tokens#refresh
sign_up_user_tokens POST /users/tokens/sign_up devise/api/tokens#sign_up
sign_in_user_tokens POST /users/tokens/sign_in devise/api/tokens#sign_in
info_user_tokens GET /users/tokens/info devise/api/tokens#info

You can look up the example requests.

Configuration

devise-api is a full configurable gem. You can configure it to your needs. Here is a basic usage example:

# config/initializers/devise.rb
Devise.setup do |config|
  config.api.configure do |api|
    # Access Token
    api.access_token.expires_in = 1.hour
    api.access_token.expires_in_infinite = ->(_resource_owner) { false }
    api.access_token.generator = ->(_resource_owner) { Devise.friendly_token(60) }


    # Refresh Token
    api.refresh_token.enabled = true
    api.refresh_token.expires_in = 1.week
    api.refresh_token.generator = ->(_resource_owner) { Devise.friendly_token(60) }
    api.refresh_token.expires_in_infinite = ->(_resource_owner) { false }

    # Sign up
    api.sign_up.enabled = true
    api.sign_up.extra_fields = []

    # Authorization
    api.authorization.key = 'Authorization'
    api.authorization.scheme = 'Bearer'
    api.authorization.location = :both # :header or :params or :both
    api.authorization.params_key = 'access_token'


    # Base classes
    api.base_token_model = 'Devise::Api::Token'
    api.base_controller = '::DeviseController'


    # After successful callbacks
    api.after_successful_sign_in = ->(_resource_owner, _token, _request) { }
    api.after_successful_sign_up = ->(_resource_owner, _token, _request) { }
    api.after_successful_refresh = ->(_resource_owner, _token, _request) { }
    api.after_successful_revoke = ->(_resource_owner, _token, _request) { }


    # Before callbacks
    api.before_sign_in = ->(_params, _request, _resource_class) { }
    api.before_sign_up = ->(_params, _request, _resource_class) { }
    api.before_refresh = ->(_params, _request, _resource_class) { }
    api.before_revoke = ->(_params, _request, _resource_class) { }
  end
end

Routes

You can configure the tokens routes with the orginally devise_for method. For example:

# config/routes.rb
Rails.application.routes.draw do
  devise_for :customers, 
             controllers: { tokens: 'customers/api/tokens' }
end

Usage

devise-api module works with :lockable and :confirmable modules. It also works with :trackable module.

devise-api provides a set of controllers and helpers to help you implement authentication in your Rails application. Here's a quick overview of the available controllers and helpers:

  • Devise::Api::TokensController - This controller is responsible for generating access tokens and refresh tokens. It also provides actions for refreshing access tokens and revoking refresh tokens.

  • Devise::Api::Token - This model is responsible for storing access tokens and refresh tokens in the database.

  • Devise::Api::Responses::ErrorResponse - This class is responsible for generating error responses. It also provides a set of error types and helpers to help you implement error responses in your Rails application.

  • Devise::Api::Responses::TokenResponse - This class is responsible for generating token responses. It also provides actions for generating access tokens and refresh tokens for each action.

Overriding Responses

You can prepend your decorators to the response classes to override the default responses. For example:

# app/lib/devise/api/responses/token_response_decorator.rb
module Devise::Api::Responses::TokenResponseDecorator
  def body
    return default_body.merge({ roles: resource_owner.roles })
  end
end

Then you need to load and prepend your decorator to the response class. For example:

# config/initializers/devise.rb
require 'devise/api/responses/token_response_decorator' # Either do this or autoload the lib directory

Devise.setup do |config|
end

Devise::Api::Responses::TokenResponse.prepend Devise::Api::Responses::TokenResponseDecorator

Using helpers

devise-api provides a set of helpers to help you implement authentication in your Rails application. Here's a quick overview of the available helpers:

Example:

# app/controllers/api/v1/orders_controller.rb
class Api::V1::OrdersController < YourBaseController
  skip_before_action :verify_authenticity_token, raise: false  
  before_action :authenticate_devise_api_token!

  def index
    render json: current_devise_api_user.orders, status: :ok
  end

  def show
    devise_api_token = current_devise_api_token
    render json: devise_api_token.resource_owner.orders.find(params[:id]), status: :ok
  end
end

Using devise base services

devise-api provides a set of base services to help you implement authentication in your Rails application. Here's a quick overview of the available services:

You can create a service by inheriting the Devise::Api::BaseService class. For example:

# app/services/devise/api/tokens_service/v2/create.rb
module Devise::Api::TokensService::V2
  class Create < Devise::Api::BaseService
    option :params, type: Types::Hash, reader: true
    option :resource_class, type: Types::Class, reader: true

    def call
      ...

      Success(resource)
    end
  end
end

Then you can call the service in your controller. For example:

# app/controllers/api/v1/tokens_controller.rb
class Api::V1::TokensController < YourBaseController
  skip_before_action :verify_authenticity_token, raise: false

  def create
    service = Devise::Api::TokensService::V2::Create.call(params: params, resource_class: Customer || resource_class)
    if service.success?
      render json: service.success, status: :created
    else
      render json: service.failure, status: :unprocessable_entity
    end
  end
end
