Rest API

This is just a step to configure the ExpressJS depencency. In our entrypoint file index.js, we will import the dependencies we need and configure the Rest API to listen some port:

const express = require('express');

// Express
let app = express();
app.listen(3000, () => console.log('Express running on port 3000'));

Let's configure the start command for NPM to test out API. For it, open the package.json file and add this key in the scripts session:

"scripts": {
    "start": "node src/index.js"
}

So now, open the command line in the project root folder and just type npm start.

It is all for this step! Easy isn't it? In the next step we will introduce the basic of GraphQL schemas.
