Getting ready

Let's create a small Express app which we'll be debugging.

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() 
const stylus = require('stylus') 
 
app.get('/some.css', (req, res) => { 
  const css = stylus(` 
    body 
      color:black 
  `).render() 
  res.send(css) 
}) 
 
app.listen(3000)
