Minimal NodeJS App

The following code will run a minimal node js app. You may use it as a boilerplate for your project.

Back to homepage

Copy the following code to your IDE:

// Import required modules const http = require('http'); // Define port const PORT = 3000; // Create HTTP server const server = http.createServer((req, res) => { // Set response headers res.writeHead(200, {'Content-Type': 'text/plain'}); // Send response res.end('Hello, world!\n'); }); // Start server server.listen(PORT, () => { console.log('Server running at http://localhost:${PORT}/'); });

Save it to a file, and call it app.js.
Then you'll be able to run it from your command line (assuming that you have NodeJS installed in your computer:

node app.js

If you want to do the same using Express.JS, you should first install the express package using NPM:

npm init npm install express

Then create and run an index.js file, similarly that what you did above:

// Import required modules const express = require('express'); // Create Express application const app = express(); // Define a route app.get('/', (req, res) => { res.send('Hello, world!'); }); // Define port const PORT = process.env.PORT || 3000; // Start server app.listen(PORT, () => { console.log('Server running on port ${PORT}'); });

And your server is ready to go!

npm start
