Project: graphql_playground - The Ruby Toolbox

This gem is a simple middleware wrapper for GraphQL Playground, a GraphQL IDE for better development workflows (GraphQL Subscriptions, interactive docs & collaboration).

gem install graphql_playground

Usage

If you use rack, you can mount it like this

require 'graphql_playground'

map '/playground' do
  use GraphQLPlayground, endpoint: '/graphql' # endpoint to your graphql server endpoint
end

Example using graphql_server gem

# app.ru
require 'graphql_playground'
require 'graphql_server'

type_def = <<-GRAPHQL
  type Query {
    hello: String
  }
GRAPHQL

resolver = {
  "Query" => {
    "hello" => Proc.new { "world" }
  }
}

map '/playground' do
  use GraphQLPlayground, endpoint: '/'
end

run GraphQLServer.new(type_def: type_def, resolver: resolver)

Launch it with

rackup app.ru

And then open http://localhost:9292/playground
