According to the latest usage statistics posted on, NodeJS currently powers over 489,251 live websites. Also, it is currently being used by several high-traffic websites including,,,, and The usage statistics and market share data posted on various websites depict that a large percentage of web developers nowadays prefer NodeJS to widely used server-side technologies. But NodeJS is completely different from conventional server-side web framework. NodeJS is developed as an open source and cross-platform JavaScript runtime.

It executed JavaScript code through Google Chrome’s V8 JavaScript engine. But NodeJS, unlike other web frameworks, enables programmers to execute JavaScript code on the server side. Hence, it becomes easier for programmers to write the frontend and backend of websites in a single programming language – JavaScript. Also, the developers can take advantage of NodeJS to accelerate development of a wide variety of applications – web applications, real-time applications, network programs, command line applications, and REST API servers. There are also a number of reasons why many web developers nowadays prefer NodeJS to other conventional server-side technologies.

Important Benefits of Using NodeJS for Development of Modern Web Applications

Extends Responsive Web Design

Most web developers nowadays adopt responsive web design to make a single website look good on both computers and mobile devices with a single codebase. NodeJS extends responsive web design by enabling programmers to write both client-side and server-side code in JavaScript. The developers can easily make the web applications compatible with major operating systems, web servers, and browsers by writing both frontend backend of websites in JavaScript.

Accelerate Isomorphic Web Application Development

At present, Universal JavaScript is one of the hottest trends in web development. Many enterprises nowadays opt for isomorphic web application development to speed up web application development and simplify web application maintenance. NodeJS facilitates the development of isomorphic web applications by converting JavaScript from a client-side programming language to server-side programming language. The enterprises can further deploy the same developers to develop and maintain the website’s frontend and backend.

A Component of MEAN Stack

The developers can further accelerate isomorphic web application development by using NodeJS as a core component of MEAN stack. MEAN stack is the acronym for its four open source components – MongoDB, ExpressJS, NodeJS, and AngularJS. AngularJS simplifies client-side development by allowing programmers to use HTML as a templating language. At the same time, MongoDB is a modern and non-relational database and ExpressJS comes with features to simplify the development of web applications and APIs. The open source components of MEAN stack further help small businesses and startups to curtail web development cost significantly.

Executes Code through V8 JavaScript Engine

As noted earlier, NodeJS is developed based on Chrome’s V8 JavaScript engine. V8 JavaScript engine has the capability to compile JavaScript code into native machine code directly. Hence, it boosts the code execution speed and performance of web server applications significantly. Also, the developers can run web applications directly within the runtime environment. They can even run the websites smoothly on without requiring specific web servers and server-side technologies.

Supports Asynchronous Programming

NodeJS is designed with a non-blocking and event-driven I/O module. The I/O module keeps the cross-platform runtime environment lightweight and extensible. Also, NodeJS performs I/O operations through a single-threaded event loop. While executing code, NodeJS sends the asynchronous tasks to the single-threaded event loop and keep executing the remaining code. Once the asynchronous tasks are executed the event loop returns to the task. Hence, it becomes easier for developers to improve web applications’ performance and user experience by processing a large number of requests simultaneously and efficiently.

Facilitates File Streaming

The non-blocking I/O model further makes it easier for programmers to accelerate the streaming of files from the file system. The web developers can even use the model to read and write the streams directly to HTTP and WebSockets. Hence, it becomes easier for them to reduce the time required to stream audio and video files. They can even accelerate transcode audio or video processing by following some simple programming hacks. For instance, the developers can easily display the audio or video output in real-time to users by shifting stdout from the web server to the web browser by using WebSockets.

Real-Time and Multi-User Application Development

As noted earlier, web developers can leverage NodeJS to build a variety of applications efficiently. But NodeJS is currently being used by web developers for building complex real-time chatting, gaming, and communication applications. NodeJS simplifies real-time application development by allowing programmers to use WebSockets as a two-way communication channel between the clients and web servers. WebSockets further speeds up client-server communication without putting additional overhead on HTTP. The loop used by NodeJS further enables programmers to build multi-user applications

Easy to Scale and Extend

The developers can easily scale and extend NodeJS according to the precise project needs. They even have the option to scale the JavaScript runtime environment both vertically and horizontally. The programmers can scale NodeJS horizontally simply by adding extra nodes to an existing web application. At the same time, they can add resources to individual nodes to scale NodeJS vertically. The scalability enables enterprises to run their websites and web applications smoothly in the long run.

Large Repository of Packages and Modules

NodeJS enables web developers to take advantage of a large and robust ecosystem of open source libraries – Node Package Manager (npm). The developers even have the option to use npm in a number of ways. They can use npm as an online repository to search and find relevant NodeJS packages and modules. At the same time, they can even use rpm as a robust command line utility to install, update, and uninstall various NodeJS packages and modules efficiently.

On the whole, NodeJS simplifies and accelerates web application development by allowing users to write server-side code in JavaScript. As an open source cross-platform runtime environment, NodeJS further helps developers to reduce web development time without increasing project overheads. However, NodeJS has been evolving consistently to meet emerging web development trends. The latest version of NodeJS accelerates JavaScript code execution by leveraging the most recent version of the V8 JavaScript engine. At the same time, it enables developers to take advantage of Universal JavaScript by supporting the new features included in JavaScript 6.
