 What is Nodejs Used For? Explained With Examples

There is no doubt about the fact that ever since its release in 2009, the popularity of NodeJS has been growing at a rapid pace. And, there are multiple reasons for this – the foremost being Node.JS is based on JavaScript. Moreover, as this cross-platform runtime environment is open source, it has a large developers’ community as well.

Businesses that wish to develop scalable network apps and render high-performance products to their target audience opt for Node.JS development and have reaped rich results over the years.

Therefore, in this blog, we will get to the details of the features that make Node.JS highly suitable for building scalable network apps. Moreover, we will also see the top implementations of Node.JS framework that have made it a hit in the market.

Top implementation of NodeJS

According to a survey made by the Node.JS foundation, the maximum application of the open-source platform (more than 85%) is done to develop web apps. This is because the apps made through Node.JS work equally well on both server-side as well as client-side.

Let us see the other top implementations of Node.JS:

Live Streaming Applications

Node.JS is used for building live streaming applications. With the proliferation of the internet and increased usage of smartphones, streaming services saw a massive rise. To understand it in brief, the streaming apps allow users to watch or listen to their favorite shows online. Leading streaming service provider Netflix moved more than half of its APS to Node.js in 2018. This is a clear indication of the fact that apps powered by Node.JS are able to handle multiple requests with ease.

For a streaming app, it is important to have a common language on both server-side and browser-side and Node JS development provides it. The open-source platform has asynchronous non-blocking I/O capabilities that make streaming operations easy and efficient.


In simple words, Microservices is an architectural style where the application is managed as a collection of services. Due to this, it becomes easier for the business organization to manage app maintenance and testing.

Did you know that NASA uses Node JS development for building its software tools? By taking the help of the dedicated Node.JS developers, the organization was able to migrate all the required data to the cloud safely. There is an in-depth study that explains how NodeJS helps in keeping the astronauts in data accessible range and safe.

Chat Applications

Node.JS is used for building char applications. Through the Node.JS framework, it is easy to handle heavy input-output operations as it is event-driven and asynchronous in nature. This is one of the prime reasons why Node.JS is essentially used to develop real-time applications.

With the help of the Socket.IO library, it becomes easier to have bi-directional, real-time, and event-based communication between the server and the browser. In addition, the Socket.IO library also assists in developing a group-chat app in less than 30 lines of coding.

Embedded Systems

It may sound a little abrupt, but hardware programming is expanding due to Node JS. Node.JS has a port called as low.js whose prime function is to allow Node.JS to run on power-efficient and cost-effective microcontroller boards.

And now it is easier to leverage all the libraries of Node.JS with the help of Tessel 2 (Robotics Development Platform) and state-of-the-art Internet of Things (IoT). Moreover, because of this, the remote Node.JS developers find it easier to create useful devices in no time.

Developing Games

Node.JS is used for building games with the help of technologies such as Socket.IO and HTML 5. Whether it is single-player or multiplayer, the expert Node.JS game developers can work directly in the browser without the help of any third-party plugins.

There are tools such as EventEmitter through which the experienced Node.js game developers find it easier to manage the complexities of multiplayer games. In addition, the EventEmitter can be used to handle and raise custom events as well. Also, through Node.JS, the app coders can share a lot of codes between the client and server sides.

Command-line Apps

We all understand that JavaScript development is ruling the roots and there is less attention given to command-line apps. But the reality is starkly different from it- a plethora of large-sized business enterprises use custom-made command-line tools.

Node.JS has different libraries such as oclif, commander, yargs, etc. through which command-line apps become fast, easy, and pocket-friendly for businesses. Therefore, web app developers who are not at home working with the back-end languages can use Node.JS with JavaScript outside the web and develop various kinds of automated solutions.

Why is Node.JS suitable for building highly scalable apps?

Business organizations should choose Node.JS as it has a number of features that make the platform impeccable for developing scalable apps. We have listed the top features of Node.JS development.

Uses single-threaded event loop model

Through this event loop model, the skilled Node.JS programmers are able to handle multiple lines without creating multiple threads. Moreover, this model helps in reducing the performance cost of switching thread contexts and prevents errors.

Also, due to the single-threaded event loop model, there are fewer chances of incorrect thread synchronization.

V8 (Open-source JavaScript Engine)

It is initially built for Google chrome and developed by the chromium project. The main function of the V8 feature is to compile the JavaScript directly to the native machine code before executing it. Thus through this, the Node.js application is able to achieve fantastic runtime performance.

Unified API

It is easier to combine Node.JS with a database or a browser that supports JSON as it adopts popular server-side development patterns. Moreover, these patterns are for a JavaScript development stack.

Data Stream Module

The top Node.JS apps don’t buffer because of the stream module. The module is an abstract interface that works with the streaming data and makes it easier to develop objects that execute it.

Node.JS development process has the capability of easily output data in huge numbers. This ability allows the skilled Node JS developers to compose the code and make the JavaScript runtime aptly suited to build scalable network apps.

Final words

There are a plethora of enterprise-level organizations other than Netflix such as PayPal, Uber, etc. that have implemented Node.JS and reaped rich benefits. Moreover, the JavaScript run-time environment is very versatile and also executes the JavaScript codes outside of the web browser.

Therefore, it is advised for business enterprises to hire remote Node.JS developers for improved web development services.
