In this Node.js tutorial for 2025, we’ll go step by step through the fundamentals:
• What Node.js actually is — and how it runs JavaScript outside the browser.
• How to use the built-in http module to create your first web server.
• How Node.js communicates with APIs and sends responses to the front-end.
• How packages like Express simplify back-end development.
• How Node.js fits into modern full-stack setups like the MERN stack.
• What is npm
• What is the node package manager

By the end, you’ll understand how servers work — and how JavaScript alone can power complete back-end applications.
