Dry::GraphQL

Build Status

dry-graphql makes dry-types and dry-struct play nicely with GraphQL. It adds a graphql_type method which will automatically generate a graphql-ruby. This takes the manual work out of maintaining multiple type definitions. Specify your dry-type, and re-use it for GraphQL.

Usage

Here is an example of using it with dry-struct:

class User < Dry::Struct
  module Types
    include Dry.Types()
  end

  attribute :name, Types::Strict::String.optional
  attribute :age, Types::Coercible::Integer
  attribute :middle_name, Types::Coercible::String
end

class UserType < User.graphql_type(only: [:name, :age])
  # you can add other fields here if you want
end

class Query < GraphQL::Schema::Object
  field :user, UserType, null: false
end

class Schema < GraphQL::Schema
  query Query
end

puts schema.to_definition # =>
# type Query {
#   user: User!
# }
#
# type User {
#   age: Int!
#   name: String
# }
end

Usage with rom-sql

To add a graphql_type method to a ROM::Relation:

require 'dry/graphql/rom'

class Users < ROM::Relation[:sql]
  extend Dry::GraphQL::ROM
end

Installation

Add this line to your application's Gemfile:

gem 'dry-graphql'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dry-graphql

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
