We have been using lots of mobile applications to carry out day to day tasks. So building applications that users can interact with in real-time has become a standard for many developers. The applications that today we use whether they are mobile, web or desktop apps have at least one real time feature. Mostly real-time messaging and notifications are the commonly used real-time features that we use in applications.

What Do Real Time Applications Do?

As mentioned before, real time applications functions within a time frame the user feels it is occurring in real time. Within real-time applications or real-time computing, the latency is set under a defined value, typically estimated in seconds.

Know the important points to consider while developing real time apps at- What To Consider While Developing Real Time Applications?
Role Of Node.js In Real-Time Applications-

1. Reusing And Sharing-
Nodejs supports microservices architecture and it allows developers to reuse the library code package and share it in various projects. It not only saves development time and increases productivity.

2. Scalable And Rapid-
As Node Js is javascript based, it executes rapidly like JS. So an application with event loop easily handles multiple client requests.

3. Event Based Server-
Real time apps handles a large number of real-time users. Node.js development supports response based on the event-driven server that supports non-blocking functioning.

4. Proxy Server-
Node js will be your best choice where intermediary administrations are necessary. To use node.js server as a proxy server, a developer needs to add a code of 20-line, and your application will turn into an ideal fit to support streaming information from numerous sources.

Features of simple chatroom-

• Change the username of the user
• Send messages
• Show if another user is currently typing a message
