NodeJS for app development

Doesn’t the idea of having an application sound fascinating?

It certainly is!

The trend of application development has taken over the world, such that almost every startup or enterprise is striving to have one!

And then, as the era we live in has become more digitized by the passing time, application development is not just a desire anymore; it has turned into a need as well. 

Developing user-friendly and interactive real-time apps, be it a mobile app, desktop app, or a web app, incorporating that ‘real-time’ factor is essential. 

But how can you effectively develop a real-time application?
The answer is with NodeJS.


NodeJS is highly recommended to develop a cutting edge real-time application for multiple purposes. The level of its competence has made it a well-loved and preferred choice worldwide. You can hire NodeJS developers to get your concept and idea developed into a real-time application!

But, this is not just it. There’s a lot more to the use of NodeJS for the development of a real-time application. And that’s exactly what we will be discussing in this article as you move ahead. 

So, without waiting further, let’s dive into this exciting topic by hitting off the basics first!

What is a Real-Time App?

A real-time application is an application functioning in a frame of time that is immediate or current in the user’s opinion. The list of some popular categories of real-time applications includes VoIP (Voice Over Internet Protocol), eCommerce platforms, IM (Instant Messaging), chatting, video conferencing, online gaming, etc. 

The real-time apps share a long list of uses and purposes. Here are a few primary and worth praising ones: 

Notification Delivery:  Grabbing the users’ attention and improving their involvement with the app, both the tasks can be done very well with real-time notifications. That’s why they have become a non-negotiable part of every modern application in today’s time. 

Real-Time Messaging: Real-time messaging is simply a blessing that makes communication so much easier. While various communication apps such as Facebook Messenger, WhatsApp, etc. are seeking most out of it, it has become a part of other niches such as delivery apps, taxi booking apps, etc. as well.  

Tracking Feature: The introduction of food delivery apps like Zomato or the taxi booking apps like Uber brought the feature of tracking the progress of a particular delivery or a ride. This real-time tracking facility has not just resulted in usability but also reliability and, to some extent, growing loyalty. 

Live Streaming: Nothing can be better than live streaming in today’s time. Real-time live streaming has gained good momentum by allowing the users to share a moment at the exact moment when they are living it. Live streaming is immensely popular and used over social media platforms. 

Facebook and Instagram are two great examples of real-time live video streaming.

Internet of Things: IoT (Internet of Things) devices experience a considerable demand for real-time features. The data that gets secured by the sensors in IoT devices is transmitted, processed, and showcased at earliest to the end-users. And since all this secured data tends to transform with passing time, the apps meant for IoT devices must be able to perform in real-time. 

What is NodeJS and How Does it Assist With Real-Time App Development?

NodeJS is a JavaScript runtime environment, which made its debut in the year of 2009. Since then, it has gained much fame and has become one of the most favorite choices of the developers in different parts of the world. 

For your needs concerning rapid and productive development, NodeJS is the ideal option. The best part about NodeJS is the support for NPM (Node Package Manager), which in turn has multiple modules to make app development using Node.js simpler and easier. 

Now speaking of a real-time app, they work effectively on the grounds of speed and scalability. And this can be handled well by making use of NodeJS with its event-driven features.

For real-time apps, data-intensive apps, applications such as forums, social media, IoT devices, and more, NodeJS is a comprehensive technology.  

NodeJS Benefits for Real-Time Application Development

The list of NodeJS advantages is enormous. However, we are shedding some light on the few major ones here that make the real-time app development a fun process: 

Server Based on Event: A real-time app at a time encounters multiple real-time users. The use of NodeJS, in this case, supports the response to be made. This is because of the event-driven server that helps in non-blocking functioning.

Scalability: Node is based on JavaScript. This lets it pull the application faster. Thus, client requests can easily be dealt with by the app having a single-threaded model and the event loop.

Sharing and Reusing: NodeJS supports microservices architecture, which enables you to use the library code package again and share it. It also promotes more productivity and time-saving.

SEO Friendly:  SEO is a need and a step ahead for your business. With such high stakes of the competition, you can not afford to miss out on it. 

And to help that, you need to make NodeJS a part of your tech stack. You can hire a Full-Stack developer who can advise you about the right tech stack along with NodeJS. The back-end rendering by NodeJS helps in improving the site’s visibility and engagement. The incredible performance further leads to a noteworthy SEO ranking. 

Proxy Server: For the need of intermediary admins, NodeJS proves to be a great option. Using the NodeJS server as a proxy server requires adding a 20-line code. Your app will then be able to assist with streaming data from different sources.

Community Support: A community of vibrant developers add more value to NodeJS. They are constantly making efforts to come up with tools along with shareable open-source modules. 

Learning Curve:  The learning curve of NodeJS is relatively smooth. If you are already familiar with the understanding and use of JavaScript, learning, and then working with NodeJS wouldn’t be a challenge for you. You can develop your real-time app in no time!
