Which framework do you prefer to use in your projects and why?

I most often prefer to use the Express.js framework for Node.js projects. It is lightweight, flexible, and has a large community, which makes it easier to find solutions and connect middleware. Express allows for quick creation of REST APIs and web applications with minimal effort.

Example of a simple server on Express:

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

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

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

For more complex projects, I consider NestJS, which is built on top of Express and provides an architecture similar to Angular, which is convenient for scalable applications.
