What experience do you have in implementing projects using Node.js?

In projects using Node.js, I have implemented server applications, REST APIs, and microservices. I used Express.js for routing and middleware, worked with databases through ORM (such as Sequelize or Mongoose). I also set up authentication using JWT and Passport.js, and implemented error handling and logging. Here's an example of a simple server with Express:

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

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

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