Node Cookbook - Third Edition

Getting ready

Let's prepare for the recipe by making a small application that causes an error creating a long stack trace.

We'll create a folder called app, initialize it as a package, install express, and create three files, index.js, routes.js, and content.js:

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

Our index.js file should look like this:

    const express = require('express')
    const routes = require('./routes')
    const app = express()
    
    app.use(routes)
    
    app.listen(3000)

The routes.js file like the following:

    const content = require('./content')
    const {Router} = require('express')
    const router = new Router()
    
    router.get('/', (req, res) => {
      res.send(content())
    })
    
    module.exports = router

And ...
