Getting ready

We're going to debug a small web server, so let's create that real quick.

On the command line, we execute the following commands:

$ mkdir app
$ cd app
$ npm init -y
$ npm install --save express
$ touch index.js

Our index.js file should contain the following:

const express = require('express') 
const app = express() 
 
app.get('/', (req, res) => res.send('hey')) 
 
setTimeout(function myTimeout() {  
   console.log('I waited for you.') 
}, 100) 
 
app.listen(3000)
