Node.js is a cross-platform and open-source JavaScript run-time environment utilised for JavaScript server-side code execution. It can run JavaScript-based applications outside of the browser. Node.js is used for creating networking and server-side applications. A majority of Node.js fundamental modules are based on JavaScript. This platform is a firm favourite of many software architects today.
According to the official Node.js documentation, it is a Chrome Javascript runtime-built platform to facilitate easy construction of scalable and agile network applications. It uses an event-driven and non-blocking I/O design for delivering efficient and lightweight functionality.
Node.js offers a combination of both a runtime environment and a JavaScript library for enabling hassle-free web application development. It can be downloaded for free and offers installer versions for Windows, Mac, and Linux operating systems. Take a look at the key features of Node.js below.
The fundamental features of Node.js that make it a platform of choice include –
1. Single-threaded – Node.js is a single-threaded language with event looping.
2. Extraordinary speed – Constructed with the V8 JavaScript engine from Google Chrome, node.js libraries can execute code at great speed.
3. Peak scalability – It offers a high level of scalability as non-blocking server responses due to event handling mechanism.
4. Open-source – Node.js is backed by an open-source community. Its community has come up with many outstanding developments to date, enabling greater functionality of Node.js applications.
5. Buffering not required – Total processing times are reduced dynamically with Node.js during video and audio uploads. Its applications do not buffer data.
6. Event-driven and asynchronous I/O – Node.js library APIs are non-blocking or asynchronous. It means that a Node.js server does not anticipate API data return. Instead, a Node.js-based server calls the next API and proceeds to it. A Node.js event mechanism notification is issued, facilitating a preceding API call response to the server. This lends to a Node.js system to be quite fast.
Node.js will continue to be one of the most popular platforms for advanced software development processes. Useful information regarding Node.js architecture and components can easily be accessed online. Browse the site for more information.
