What experience do you have in developing applications using Express.js?

Express.js is a popular framework for Node.js that simplifies the creation of web applications and APIs. In my experience, I have used Express for:

• Creating RESTful APIs with routing and request handling.
• Connecting middleware for parsing request bodies, error handling, and authentication.
• Integrating with databases (e.g., MongoDB via Mongoose).

Example of a simple server on Express:

const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('Hello, Express!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
