• API Documentation

Installation

Install from RubyGems by adding it to your Gemfile, then bundling.

# Gemfile
gem 'graphql'

$ bundle install

Getting Started

See "Getting Started" on the website or on GitHub

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.
• Features & patches are welcome! Consider discussing it in an issue or in the #ruby channel on Slack to make sure we're on the same page.
• Run the tests with rake test or start up guard with bundle exec guard.
• Build the site with rake site:serve, then visit http://localhost:4000/graphql-ruby/.

To Do

• StaticValidation improvements (in progress ??)
  • Use catch-all type/field/argument definitions instead of terminating traversal
  • Reduce ad-hoc traversals?
  • Validators are order-dependent, is this a smell?
  • Tests for interference between validators are poor
  • Maybe this is a candidate for a rewrite?
• Relay:
  • Reduce duplication in ArrayConnection / RelationConnection
  • Improve API for creating edges (better RANGE_ADD support)
  • If the new edge isn't a member of the connection's objects, raise a nice error
• args should whitelist keys -- if you request a key that isn't defined for the field, it should 💥
• Support non-instance-eval .define, eg .define { |defn| ... }
• Add immutable transformation API to AST
  • Support working with AST as data
  • Adding fields to selections (__typename can go anywhere, others are type-specific)
  • Renaming fragments from local names to unique names
