GraphQL-Tools-Types
===================

Custom Scalar Types for GraphQL-Tools

About
-----

This Node.js module provides the custom scalar types Void, Integer, Float,
String, Date, Universally Unique Identifier (UUID) and
JavaScript Object Notation (JSON) for
GraphQL Tools,
a wrapper around the GraphQL engine
GraphQL.js.

Installation
------------

``shell
$ npm install graphql-tools-types
`

Usage
-----

`js
import UUID from "pure-uuid"
import * as GraphQL from "graphql"
import * as GraphQLTools from "graphql-tools"
import GraphQLToolsTypes from "graphql-tools-types"
