Node.js Overview

Node.js is a fast, scalable, open-source JavaScript runtime environment built on Chrome's V8 engine. It enables developers to run JavaScript on the server side, making it ideal for building high-performance, real-time applications. With frameworks like Express.js, developers can create robust APIs and backend systems quickly.

Core Components

Node.js JavaScript runtime environment.
Express.js Minimalist web framework for Node.js.
MongoDB/MySQL Databases for structured and unstructured data.

How Node.js Works


Client sends a request via browser or API call.

Node.js receives the request on a single-threaded event loop.

Non-blocking I/O operations handle database or API calls asynchronously.

Node.js returns the processed data to the client.

Key Advantages

High performance with event-driven architecture.
Large npm ecosystem for modules and packages.
Ideal for real-time apps like chat and streaming.
