Graphql API Code Cookbook

Problem

Most of the APIs request an endpoint to access a predefined data structure. If you want to access other resources, it is necessary to request another endpoint, it makes the procces kind of tricky.

We only define a single endpoint (for example http://example/graphql).
Since this is a query language, all actions are done through a POST.

Solution

GraphQL allow us to retrieve only the data we need by using a query language for web APIs.

Recipe

CRUD GraphQL API with Nodejs, Express & MongoDB

Create a new directory to store the project, run npm init to configure the new project
Run npm install to create our package.json file
Create a server.js file (entry point for our server)
Create the src folder and the below required folders and files:
1. Create src/schema directory and an index.js file (will contain the business logic)
2. Create a src/resolvers directory and an index.js file.
3. Create an src/models directory and a post.js which holds what a post should look like.
```
├── src
│   ├── schema
│   │   └── index.js
│   ├── resolvers
│   │   └── index.js
│   └── models
│       └── post.js
├── package-lock.json
├── package.json
└── server.js
```

Install the dependencies

Using npm

  # npm
  $ npm install --save express express-graphql graphql body-parser

Using yarn

  # yarn
  $ yarn add --save express express-graphql graphql body-parser

You can also install "nodemon" locally to avoid having to restart your server with each change

  $npm install --save-dev nodemon

Also you need to update your "package.json" for using "nodemon".

  "scripts": { "start": "nodemon server.js"}
