How to do it...

We only need one module, the http module.

Let's require it:

const http = require('http') 

Now we'll define a host and port which our HTTP server will attach to:

const host = process.env.HOST || '0.0.0.0' const port = process.env.PORT || 8080 

Next, let's create the actual HTTP server:

const server = http.createServer((req, res) => {   if (req.method !== 'GET') return error(res, 405)   if (req.url === '/users') return users(res)   if (req.url === '/') return index(res)   error(res, 404) }) 

In the request handling function we passed to the http.createServer method, we reference three other functions, error, users, and index.

First let's write our route handling functions:

function users (res) {  res.end('{"data": [{"id": 1, "first_name": ...
