GraphQL - Server Side (Part 1)

How to setup GraphQL server side using Apollo. Updated!!

Step 1:

First install Apollo Server and Graphql packages

npm install apollo-server graphql

In the server folder (if you have seperated server and client code into different folders) create a file called schema.js

Step 2:

Next we need to call the gql template literal from apollo-server

const { gql } = require("apollo-server");

Step 3:

Now time to define our types

type Book {
  id: ID!
  title: String!
  author: Author!
  thumbnail: String
  length: Int
  modulesCount: Int
}

type Author {
    id: ID!
    name: String!
    photo: String
}

You'll notice that we use an exclimation mark at the end of some of the fields. This is to indicate that the value cannot be null.
