Level Up Your Node.js Apps With Modules

Boost productivity and build sustainable systems

Welcome aboard, fellow developer! Today, I want to share a game-changing concept that revolutionized my Node.js adventures — modules. You guessed it: breaking down sprawling spaghetti nightmares into digestible bites drastically improves productivity and fosters maintainable ecosystems. Dive in as I demystify using modules in Node.js applications.

Getting Started

First things first, initialize a fresh project and install essential tooling:

mkdir awesome-app && cd $_
npm init -y
npm install express body-parser --save

Next, create a humble entry point — index.js:

// index.js
const express = require('express');
const bodyParser = require('body-parser');

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));

app.get('/', (req, res) => {
  res.send('<h1>Home sweet home</h1>');
});

app.listen(8000, () => {
  console.log('Listening on port 8000');
});

Now, run our shiny new toy:

node index.js
# Open http://localhost:8000/ in your favorite browser
