Node JS

Node JS

Node.js is a cross-platform, open-source back-end JavaScript runtime environment that runs JavaScript code outside of a web browser using the V8 engine. Developers can use Node.js to make command-line tools and server-side scripting, which involves running scripts on the server before transmitting on the page to the user's browser. As a result, Node.js represents a "JavaScript everywhere" paradigm, uniting online application development around a single programming language rather than employing different languages for server-side and client-side scripts.

Asynchronous I/O is possible because to Node.js' event-driven architecture. These design choices are aimed at increasing throughput and scalability in web applications with a lot of input/output activities, as well as real-time Web applications (e.g., real-time communication programs and browser games).

The Node.js distributed development project was previously managed by the Node.js Foundation, however that organization has now merged with the JS Foundation to form the Open JS Foundation, which is funded by the Linux Foundation's Collaborative Projects program.


Using JavaScript and a collection of "modules" that handle several essential capabilities, Node.js facilitates the building of Web servers and networking utilities. File system I/O, networking (DNS, HTTP, TCP, TLS/SSL, or UDP), binary data (buffers), cryptographic routines, data streams, and other essential functions are all supported by modules. The modules of Node.js make use of an API that makes creating server applications easier.

The only native language supported by Node.js is JavaScript, but numerous compile-to-JS languages are available. As a result, Node.js applications can be created in a variety of programming languages, including CoffeeScript, Dart, TypeScript, ClojureScript, and others.

The Node.js programming language is generally used to create network programs such as Web servers. The most notable distinction between Node.js and PHP is that most PHP functions block until they are complete (ones run only after preceding commands have been completed), whereas Node.js functions are non-blocking (commands execute concurrently or even in parallel, and use callbacks to signal completion or failure).

Official support for Node.js is available for Linux, macOS, and Microsoft Windows 8.1 and Server 2012 (and later), with tier 2 support for SmartOS and IBM AIX, as well as experimental support for FreeBSD. OpenBSD is also supported, with LTS versions for IBM I (AS/400) available. The provided source code can also be constructed on operating systems that are similar to those that are officially supported, or updated by third parties to support additional operating systems like NonStop OS and Unix servers.
