GraphQL Auth

This gem provides an authentication mechanism on a GraphQL API. It use JSON Web Token (JWT) and Devise logic.

Installation

Add this line to your application's Gemfile:

gem 'graphql-auth'

And then execute:

$ bundle

Or install it yourself as:

$ gem install graphql-auth

Then run the installer to create graphql_auth.rb file in your initializers folder.

rails g graphql_auth:install

Make sure to read all configurations present inside the file and fill them with your own configs.

Devise gem

Use Devise with a User model and skip all route

Rails.application.routes.draw do
 devise_for :users, skip: :all
end

Usage

Make 'JWT_SECRET_KEY' and 'APP_URL' available to ENV

JWT_SECRET_KEY=
APP_URL=

Make sure the Authorization header is allowed in your api

Rails.application.config.middleware.insert_before 0, Rack::Cors do
  allow do
    origins '*'
    resource '*',
             headers: %w(Authorization Expires RefreshToken),
             methods: :any,
             expose: %w(Authorization Expires RefreshToken),
             max_age: 600
  end
end

Make sure to include Graphql::AuthHelper in your GraphqlController. A context method returning the current_user will be available

class GraphqlController < ActionController::API

  include Graphql::AuthHelper

  def execute
    variables = ensure_hash(params[:variables])
    query = params[:query]
    operation_name = params[:operationName]
    result = ::GraphqlSchema.execute(query, variables: variables, context: context, operation_name: operation_name)
    render json: result

    ...

Make sure to implement GraphqlAuth in your MutationType to make auth mutations available

class Types::MutationType < Types::BaseObject
  implements ::Types::GraphqlAuth
end

Customization

If you can to customize any mutation, make sure to update the configurations

GraphQL::Auth.configure do |config|
  # config.token_lifespan = 4.hours
  # config.jwt_secret_key = ENV['JWT_SECRET_KEY']
  # config.app_url = ENV['APP_URL']

  # config.user_type = '::Types::Auth::User'

  # Devise allowed actions
  # Don't forget to enable the lockable setting in your Devise user model if you plan on using the lock_account feature
  # config.allow_sign_up = true
  # config.allow_lock_account = false
  # config.allow_unlock_account = false

  # Allow custom mutations for signup and update account
  # config.sign_up_mutation = '::Mutations::Auth::SignUp'
  # config.update_account_mutation = '::Mutations::Auth::UpdateAccount'
end
