Node.js is an open-source JavaScript runtime environment that allows developers to run JavaScript code outside the browser, typically on the server side. It is built on Google Chrome’s V8 engine and is widely used for backend development.
In web development, Node.js enables developers to build fast, scalable, and event-driven server applications such as APIs, real-time systems, and microservices. It is commonly used in full-stack JavaScript development.
For example:
- A backend API is built using Node.js to handle user authentication and data storage.
- A chat application uses Node.js for real-time message communication.
- An e-commerce backend processes orders and payments using Node.js services.
- A streaming platform handles high traffic requests with Node.js server architecture.
Common technologies and concepts related to Node.js include:
- JavaScript
- Express.js
- Event Loop
- Non-blocking I/O
- NPM (Node Package Manager)
- REST APIs
- Backend Development
- JSON Handling
- Microservices Architecture
