Node.js

Overview of Node.js

Node.js is a free, open-source JavaScript runtime environment that enables developers to run JavaScript code outside web browsers. Built on Chrome's V8 JavaScript engine, it provides a cross-platform solution for creating servers, web applications, command-line tools, and automation scripts. The platform uses an event-driven, non-blocking I/O model that makes it exceptionally efficient for data-intensive real-time applications running across distributed devices.

As a versatile development platform, Node.js serves web developers, backend engineers, and full-stack programmers working on scalable network applications. Its extensive ecosystem includes the npm package manager, which hosts thousands of reusable modules for various development needs.

How to Use Node.js

Getting started with Node.js involves downloading the installer from the official website for your operating system. Once installed, you can run JavaScript files directly from the command line using the node command. Developers typically begin by creating package.json files to manage dependencies, then install required packages via npm. The platform supports immediate execution for testing scripts or can be configured to run persistent server applications that handle HTTP requests, file operations, and database connections efficiently.

Core Features of Node.js

1. JavaScript Runtime – Execute JavaScript code server-side with Chrome's V8 engine
2. Event-Driven Architecture – Handle multiple concurrent connections efficiently
3. Non-Blocking I/O – Perform asynchronous operations without waiting
4. Cross-Platform Support – Run applications on Windows, macOS, and Linux
5. Package Ecosystem – Access thousands of modules through npm registry
