What technologies and tools do you use for developing the server-side of the project?

The following technologies and tools are commonly used for developing the server-side with Node.js:

• Express.js — a popular framework for creating REST APIs and web applications.
• Node.js — the platform itself for executing JavaScript on the server.
• Databases — for example, MongoDB with Mongoose, PostgreSQL with Sequelize or TypeORM.
• Testing tools — Jest, Mocha, Chai for writing unit and integration tests.
• Asynchronous tools — async/await, promises.
• Docker — for containerizing the application and simplifying deployment.
• PM2 — a process manager for running and monitoring Node.js applications in production.

Example of a simple server on Express.js:

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

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

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