Why Choose Node.js For Real-Time Application Development

The digital world is kept growing and app development is fast-paced. Many applications are developed with real-time interactions with users. These kinds of applications are known as real-time applications (RTA). Real-time applications are the programs that function within a time frame (these are measured in seconds). The prime use of the real-time application is messaging and delivery notification; it can be either a web application, desktop app, or a mobile app. These apps are used for several purposes.

The best real-time apps are instant messaging, online gaming, e-commerce transaction, voice stores solution, VoIP (voice over Internet Protocol), IM (instant messaging), and video conferencing applications.

Where Are Real-Time Apps Used?

The real-time application is used in notification delivery, messaging, and tracking. Let’s look in detail at how a real-time app is in use.

Real-time messaging

Today many people use real-time messaging apps such as Facebook Messenger, WhatsApp, and much more.  You can also notice the real-time messaging feature within the taxi booking apps, delivery apps as a collaborative form.

Real-time tracking

One of the best examples of a real-time tracking application is Uber. The on-demand apps like taxi booking and delivery app track the location of the taxi ride or delivery for the user in real-time. The app user can get the real-time update which enhances the usability and reliability of the application.

Real-time Notification Delivery

Real-time notifications are a game-changer that increases user engagement with the app. Many top brand applications utilize this feature for better client commitment and conversion.

Live Streaming

On a live stream, users can interact in real-time. Apps integrated with live video streams becoming more popular.  The best examples of this Instagram and Facebook app with live video streaming features

IoT Devices

For IoT devices real-time features are essential. The data captured by the sensors placed in IoT devices are transmitted, processed, and displayed to the end-users with a minimum time frame. Applications working with IoT devices ought to have the option to receive and send information continuously in real-time

Introduction on Node.js

Node.js is an open-source cross-functional platform· Node.js runs on various platforms like Windows, Mac OS, Linux, Unix, etc.  In many web app developments, Node.js plays a precise role for example LinkedIn, Netflix; Uber uses Noje.js on application development. The primary backend of eBay and AliExpress is Node.js.  More than 23 million developers in the world are using Node.js and it keeps increasing.

Why Node.js? It is built on V8. It is a high-performance open-source JavaScript engine. For outstanding performance, Node.js applies an event-driven, non-blocking I/O paradigm.

Node.js is a really scalable network application, massively reduces the application development time, and offers benefits in performance and other perks. Node.js is remarkably fast for multi-user real-time data. No surprise, numerous startups lean toward Node.js, and giants like Netflix, PayPal, and eBay have joined the hype.

Node.js is best suitable for Real-time web applications, Messaging apps, Streaming applications, Chat programs, Multiplayer games, Social media apps, Virtual emulators, Collaboration tool, and API

Node.js Application Development

Advantages of Node.js for Developing Real-Time App Development

1. Data Sync

Node.js non-blocking I/O feature can be best used by the developer. It helps in rapid information or data transmission among users and servers.

2. Reusing & Sharing

The micro service architecture feature is supported by these programming languages. It allows the developer to reuse the bundle of library code and allows sharing on numerous projects.

3. Event-Based Server

Real-time applications deal with large real-time users. Node.js development supports event-driven servers and non-blocking functioning.  Let’s drive what is meant by event-driven and non-blocking I/O.  At the point when you call the server the request is received and registered as a function. Instead of the actual data Node.js registers a function.

Let’s assume, the event cycle is treated as a waiter at a restaurant by Node. At whatever point a request is made, the node takes that and registers the callback function. The waiter doesn’t require waiting till the food is ready in the same way the event cycle will be free once the request is delivered.

4.  Proxy Server

Node is the better option when there are intermediary admin needs.  To utilize Node server as a proxy server the developer needs to include a 20 line code and your application will turn into an ideal fir for helping for streaming information from alternate sources

5. Fast & Scalable

Node is a JavaScript-based program so its execution will be faster like JS.  A single-threaded architecture model with an event loop application can easily handle multiple user requests.

6. SEO Friendliness

To survive in online business SEO is necessitous. If you want your application to be SEO (Search engine optimization) friendly then you have to incorporate the node on the app development tech stack

The backend rendering by Node.js gives you more visibility and engagement for the website. If you use Node for your app the user not only gets the high speed and high-end performance but also helps you rank on the search engine.


At least one real-time feature is included in the app we use today; the application can be of any type of mobile, desktop, or web application. In fact, Node.Js is one of the best programming languages to develop real-time apps.

With the amazing Node.js feature you can develop on-demand real-time applications like taxi booking, chat application, online gaming, delivery app, and much more. The non-blocking driven servers and event-based server features on Node will be perfect for developing real-time applications that are scalable with high-speed performance.

Node.Js provides an uninterrupted two-way connection to the app like ad server, social media, and forums. Application created utilizing node permits the server and client to communicate and exchange information uninhibitedly and without any problem. The above advantages of Node.Js show that Node.js will be the ideal fit for real-time application.
