## Components

### graphql-common
This module controls the configuration for GraphQL service and share some static variables
with other modules to make the dependencies much simpler. 

### graphql-router
This module provides RouteHandler and SchemaProvider interfaces and implement both GET and
POST handlers for GraphQL. 

## Middleware Handlers:

### graphql-security
This is the handler that should be put before graphql-validator. There is no need to
do any validation if JWT token does not exist in the request header.

### graphql-validator
Basic request validation for the graphql path and methods. It is the first line of
validation right after graphql-security and it doesn't have any knowledge about the
graphql query parameter and body.

## Tutorial

### [Hello World](https://doc.networknt.com/tutorial/graphql/helloworld/)

This is a very simple Hello World query to show you how to get GraphQL up and running with
light-codegen without using GraphQL IDL.

### [Star Wars](https://doc.networknt.com/tutorial/graphql/starwars/)

This is a similar example as Hello World with IDL to trigger the generation. It is utilize the
star wars GraphQL IDL downloaded from the Internet.
 
### [Mutation](https://doc.networknt.com/tutorial/graphql/mutation/)

This example shows you how to create a full blown GraphQL service with both query and mutation.

### [Mutation IDL](https://doc.networknt.com/tutorial/graphql/mutation-idl/)

This is the same example like the mutation but is generated from a schema. 

### [Relay Todo](https://doc.networknt.com/tutorial/graphql/relay-todo/)

This is to show you how to build a GraphQL service that is working with Relayjs.
