Key Reasons for Using Node.js to Build Real-time Applications

Below are prominent reasons that make Node.js a perfect fit to develop real-time mobile apps

1. Scalability

The single-threaded event-driven architecture of Node.js makes it capable of performing multiple tasks and processing numerous requests quickly without clogging the RAM. Node.js is built on a V8 engine powered by Google that compiles source code written in Javascript into machine language within a shorter time span. Furthermore, the non-blocking I/O feature of Node.js handles asynchronous requests without blocking a thread due to which it is considered as the most suitable runtime environment for building real-time apps.

2. Cost-effective

Node.js enables developers to execute similar source code on both client and server. You don’t need to hire separate teams of developers to build the frontend and backend of your real-time application. Writing source code in a single language and executing it on both client and server will not only save a lot of time but also help you build your mobile app within minimal cost and resources.

3. Flexibility

Node.js is equipped with multiple in-built libraries, plugins, and ready-to-use codes that allow developers to build an app without consuming a lot of time. Due to its flexible nature, it enables businesses of all sizes to reduce the time-to-market of their applications. Since Node.js is lightweight and easier to use, it also helps app development teams accelerate their overall development speed.

4. Modularity

The microservices-based architecture of Node.js helps developers to modify existing apps without any hassle. Node.js supports modular design through which one can easily break the app design into smaller modules and integrate additional features & microservices into the basic app functionality. Updating the existing modules and adding new ones on a regular basis could play a significant role in improving the responsiveness of your application.

Business Benefits of Integrating Real-Time Features in Your Mobile App

Reduced Cost 

Sharing large amounts of data with your workforce & clients utilizing real-time apps will not only lessen infrastructure usage but also saves a huge amount of time. Reduced reliance on infrastructure will result in reduced expenses. 

Improved Customer Loyalty

Data transparency is something that helps businesses to improve customer relationships. Clients will be able to track and monitor work reports in a transparent manner with real-time apps which will help your business gain customer loyalty.

Quicker Access to Data

Whether it's a small scale organization or large enterprise, the speed of access to data is one of the major benefits of integrating real-time features into business apps. Sharing data in real-time will enable the entire staff of your organization to access the information within just a few clicks.

Enhanced Inter-team Collaboration

Mobile apps embedded with real-time features like instant messaging, live video streaming, and push notifications to play a significant role in streamlining inter-team communication and optimizing the internal business process.

Must-have Real-Time Features for Your Business App

Here are some must-have real-time features that you must add to your business app to make it a sheer success:

  • Push Notifications: To make clients aware of the meeting schedules, latest market trends, and any other project updates. Apart from that, push notifications could also be used to stimulate user engagement, increase conversion rates, target the right users, track actionable metrics, and enhance brand consistency.
  • Real-Time Messaging: To enable smooth and flawless communication between clients and stakeholders. Unlike emails where both sender and receiver have to wait for notifications to download from the server, you can communicate with your clients in real-time using this feature.
  • Live Video Streaming: To share valuable information with your clients via live video broadcasting. Moreover, you can also use live video streaming as part of your training program to train new joiners.   
  • GPS Location Tracking: To share the geographic coordinates of your real-time location with your clients. This feature also enables you to provide up-to-the-minute arrival details to your customers.
