Key Features
- Asynchronous and Event-Driven: The Node.js library’s APIs are all asynchronous (non-blocking) in nature. A server built with Node.JS never waits for data from an API. After accessing an API, the server moves on to the next one. In order to receive and track responses of previous API requests, it uses a notification mechanism called Events.
- Single-Threaded: Node.js employs a single-threaded architecture with event looping, making it very scalable. In contrast to typical servers, which create limited threads to process requests, the event mechanism allows the node.js server to reply in a non-blocking manner and makes it more scalable.
- Cross-Platform: Node.js is a cross-platform runtime environment that allows you to create server-side and networking applications. Node.js apps are written in JavaScript and run on OS X, Microsoft Windows, and Linux utilizing the Node.js runtime.
- Large Ecosystem: Node.js has a built-in library of core modules that provide functionalities like file system operations, network communication, and cryptography. It also supports third-party modules that can be installed and managed using the npm command-line tool. These modules extend the capabilities of Node.js and offer features such as web frameworks, database drivers, and testing tools. You can find and download thousands of third-party modules from the npm registry, a public database of Node.js packages.. NodeJs facilitates the integration of programming languages with APIs, other languages, and a variety of third-party libraries.
- JavaScript Everywhere: Desktop App, Mobile App, Crypto, Machine Learning. ****NodeJS is being used in mobile application development in addition to online development.
