Node.js For Real-Time Application Development

In this world of digital transformation where every industry is advancing, developing user-friendly applications is the need of the hour. Developers today focus on building applications on which users can interact in real-time. Be it a web-app, desktop-app, or mobile app; each has a real-time feature incorporated in it. The two-most highly used features in real-time applications are real-time messaging and notifications. But for these applications to work smoothly and dynamically, we need a robust programming framework at its back end. Node.js is essentially one of the most used and credible frameworks for doing so. It is advisable to hire Node.js developers for delivering a user-friendly and interactive application development project. To understand the working of Node.js for real-time applications, let us first understand what real-time applications are.

What Does a Real-Time Application Do?

This application performs many features within a time period, and the user feels that it is occurring instantly or in real-time. The best instances of real-time applications are e-commerce transactions, chatting online, instant messaging, Voice over Internet Protocol, and Online gaming.

Where Are These Applications Used?

Notification delivery and messaging are two essential use cases of real-time applications. These applications are used for several purposes:


In order to increase user involvement with applications, companies provide real-time notifications in their app solutions. It has proved to be a game-changer in terms of increasing user activity on applications. In today’s times, it is hard to find an application that doesn’t give notifications in real-time.


Today, most of us know the usage of real-time messaging through applications like Whatsapp, Facebook Messenger, and many other similar applications. However, real-time messaging is not just restricted to real-time applications. We can find real-time messaging in delivery applications, collaborative platforms, and on-demand taxi booking applications.


The launch of on-demand taxi booking apps like Ola and Uber made real-time tracking a necessity. Their real-time tracking updates enhance the credibility and authenticity of such applications.

Live Streaming

Real-time live video streaming is becoming very famous amongst users. After the social media applications like Instagram and Facebook integrated live video streaming features, many businesses have used this for effective social media promotions of their products and services.

It offers two-way connections to applications like social media, forums, stock exchange software, and ad servers. For real-time IoT devices and data-intensive applications, Node.js is a blessing in disguise as it is quick and scalable.

An application built on Node.js enables the server and client to exchange data and communicate freely. For creating dynamic projects on Node.js, it is advisable to hire Node.js programmers; as they are skilled to deliver an effective and flawless project.

Benefits of Node.js in Real-Time Applications

An Event-Based Server

Real-Time applications deal with numerous real-time users. The Node.js development supports response depending on the event-based server, which assists in non-blocking functioning. 

Data Syncing

A skilled developer makes an applicable use of non-blocking I/O features. Data transmission between server and client is accommodated quickly. 

Fast and Scalable

As Node.js is a Javascript extension, it pulls an application faster like Javascript. Therefore, an application with an event-loop and single-threaded model can conveniently deal with various client requests.

Re-using and Sharing

Node.js assists microservice architecture as it is a real-time programming language. It allows the Node.js developers to use the library code packages again and use it in numerous projects. Moreover, it helps developers to foster increased productivity and manage time effectively.

Usability of SEO

It is hard to survive in a digital world without using SEO. In case you don’t want your application to lose out on the opportunity of using SEO, it is advisable to incorporate Node.js in the app development tech stack. Node.js backend rendering provides a site more visibility and increases engagement.

Proxy Server
