Build Status Gem Version Maintainability Test Coverage

Generates a full GraphQL API using introspection of Mongoid or ActiveRecord models.

API Dodocumentation

The API Documentation that displays how to use the queries and mutations that Graphoid automatically generates.


This gem depends on the GraphQL gem. Please install that gem first before continuing


Add this line to your Gemfile:

gem 'graphoid'
$ bundle install


Create the file config/initializers/graphoid.rb And configure the database you want to use in it (:mongoid or :active_record)

Graphoid.configure do |config|
  config.driver = :mongoid


You can determine which models will be visible in the API by including the Graphoid Queries and Mutations concerns

class Person
  include Graphoid::Queries
  include Graphoid::Mutations


You can find an example that uses ActiveRecord in the Tester AR folder
And an example with Mongoid in the Tester Mongo folder
In this same repository.

Thank You !!

Ryan Yeske for the whole idea and for validating that metaprogramming this was possible.

Andres Rafael for working so hard on connecting the gem on the frontend and finding its failures.
