Node.js, an open-source, cross-platform back-end JavaScript runtime environment that operates on a JavaScript Engine and executes JavaScript code outside a web browser, develops scalable network applications.

Developers use JavaScript to create command-line tools and for server-side scripting, which produces dynamic web page content on the server before the page is transmitted to the user's web browser through Node.js. Thus, Node.js symbolizes a "JavaScript everywhere" paradigm, bringing web application development under a single programming language rather than segregating it across server-side and client-side scripting languages.

Architecture

The event-driven design of Node.js supports asynchronous I/O. These design decisions attempt to maximize performance and scalability for real-time web applications with numerous input/output activities, for example, real-time communication programs and browser games.

Node.js builds quick web servers in JavaScript by integrating event-driven programming into web servers. Without threading, developers can build scalable servers using an abridged version of event-driven programming that uses callbacks to indicate when a task is finished. Node.js combine JavaScript's ease of use and the strength of Unix network programming.

Since Google's V8 JavaScript engine was open-sourced under the BSD license, Node.js was built on top of it. It is adept at using standard internet protocols, including HTTP, DNS, and TCP. Another well-known language, JavaScript, made Node.js available to the web development community.

Industry Application

Among the businesses that employ Node.js software are GoDaddy, Groupon, IBM, LinkedIn, Microsoft, Netflix, PayPal, SAP, Walmart, Yahoo!, and Amazon Web Services. 

Numerous open-source libraries are available for Node.js. The majority of them are maintained on the npm website. Web frameworks have been built by the open-source community to speed up the creation of apps. Connect, Express.js, Socket.IO, Feathers.js, Koa.js, Hapi.js, Sails.js, Meteor, Derby, and numerous other frameworks fall under this category. There are also several packages available for interacting with other languages or runtime environments like Microsoft.NET.

Specific editing and debugging tools are available in contemporary desktop IDEs for Node.js applications. These IDEs include Atom, Brackets, JetBrains WebStorm, Visual Studio Code, Microsoft Visual Studio with Node.js Tools for Visual Studio, or TypeScript with Node definitions, NetBeans, and Nodeclipse Enide Studio, Eclipse-based. Node.js is also supported by a few web-based online IDEs, including the visual flow editor in Node-RED, Cloud9 IDE, Codeanywhere, Codenvy, and Codenvy.

Numerous cloud hosting services, including Jelastic, Google Cloud Platform, AWS Elastic Beanstalk, Joyent, and others, support Node.js.
