Master Node.js with tutorials on Stripe payments, Cloudinary uploads, REST APIs, and backend architecture. Step-by-step guides with examples.

What is Node.js?

Node.js is a powerful JavaScript runtime environment that allows you to execute JavaScript code on the server-side. Built on Chrome's V8 JavaScript engine, Node.js enables developers to build scalable, high-performance network applications using JavaScript for both frontend and backend development.

Node.js is used by major companies like Netflix, LinkedIn, Uber, PayPal, and eBay for building fast, scalable backend services. Its event-driven, non-blocking I/O model makes it perfect for data-intensive real-time applications that run across distributed devices.

Key Features of Node.js:

  • Server-Side JavaScript: Use JavaScript for both frontend and backend development
  • Asynchronous & Event-Driven: Non-blocking I/O operations for high performance
  • NPM Ecosystem: Access to millions of packages through npm (Node Package Manager)
  • Scalable: Built for building scalable network applications
  • Fast Execution: Powered by V8 engine for fast JavaScript execution
  • Cross-Platform: Runs on Windows, macOS, and Linux
