# GraphQL Schema

Classes to more conveniently access the GraphQL instrospection
result rather than using the parsed json directly as a hash.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'graphql_schema'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install graphql_schema

## Usage

```ruby
require 'graphql_schema'
require 'json'

introspection_result = JSON.parse(File.read("schema.json"))
schema = GraphQLSchema.new(introspection_result)
schema.types.select(&:object_type?).each do |type|
  type.fields.each do |field|
    puts "#{field.name} -> #{field.type.name}"
  end
end
```
