Now a days building a real-time application is increased among developers. Most of the application, we are using today whether they are mobile or desktop applications they have real-time features in it. For example, consider the messenger app that contains real-time messaging and notification, both of them are used commonly as a real-time features in applications.

In this story, I will introduce you to develop a real-time application using node.js by building a messenger app. Though this story will explain about the specific use cases, you can apply this strategy in other scenario also.

Before getting into the topic, you have to know little bit of node.js, it is one of the powerful programming language to build real-time apply due to its asynchronous nature.

Features of Real-time Application

You can find what are the features required to build real-time application. They are,

Real-time Messaging

We all familiar with the use of messenger applications like WhatsApp, Facebook etc. These real-time application not only used for purely messaging services. We can get real-time messaging services like delivery apps, taxi apps and other collaborative platforms.

Notification Delivery

Enabling real-time notification is quite complex when the user engagement increased drastically. So, this is the reason you can see a modern application that does not deliver notification in real-time to the user.

Live Streaming

With the use of live stream the user can able to interact with other user are becoming more popular in social media platforms. So we can integrate live video streams into the application. Best examples are Facebook and Instagram live video streaming features.
