graphql 
A Ruby implementation of GraphQL.
Installation
Install from RubyGems by adding it to your Gemfile, then bundling.
# Gemfile
gem 'graphql'$ bundle install
Getting Started
$ rails generate graphql:install
After this, you may need to run bundle install again, as by default graphiql-rails is added on installation.
Or, see "Getting Started".
Upgrade
I also sell GraphQL::Pro which provides several features on top of the GraphQL runtime, including Pundit authorization, CanCan authorization, Pusher-based subscriptions and persisted queries. Besides that, Pro customers get email support and an opportunity to support graphql-ruby's development!
Goals
- Implement the GraphQL spec & support a Relay front end
- Provide idiomatic, plain-Ruby API with similarities to reference implementation where possible
- Support Ruby on Rails and Relay
Getting Involved
- Say hi & ask questions in the #ruby channel on Slack or on Twitter!
- Report bugs by posting a description, full stack trace, and all relevant code in a GitHub issue.
- Start hacking with the Development guide.
