The MERN stack—MongoDB, Express, React, and Node.js—is one of the most popular full-stack frameworks today. In this post, I'll cover the essentials of each part of the stack and share some tips on how to build robust and scalable applications.
// Example of a simple Express server
const express = require('express');
const app = express();
app.get('/', (req, res) => res.send('Hello, MERN Stack!'));
app.listen(3000, () => console.log('Server is running on port 3000'));
