WebRTC (Web Real- Time Communication)



WebRTC is a modern web application where you can easily stream audio, video and share files with people through web browsers and mobile applications.

In this blog, I will give you a short description of WebRTC. Let's start...

What is WebRTC?

WebRTC sets up a peer-to-peer connection between two browsers or two mobile applications.

Go to a below link and see the video about webRTC.

A short history of WebRTC

Gmail video chat become more popular in 2008, and in 2011 Google introduced Hangouts, which uses the Google Talk service. Google bought a company that name is GIPS, which had developed many components required for RTC( Real-Time Communication), such as codecs and echo cancellation techniques. Google open-sourced the technologies developed by GIPS and engaged with relevant standards bodies at the IETF and W3C to ensure industry consensus. In May 2011, Ericsson built the first implementation of WebRTC.

WebRTC is used in various apps like WhatsApp, Facebook Messenger, etc.



WebRTC mainly works on three APIs:

  • MediaStream
  • RTCPeerConnection
  • RTCDataChannel 

All the above three APIs supported in mobile and desktop by Chrome, Safari, Firefox, Edge, and Opera.


Get access to the data stream, such as user microphone and camera.

Go to the below link and get a demo of MediaStream



RTCPeerConnection is the webRTC component that handles stable and efficient communication of streaming data between peer connection.

The main work of the RTCPeerConnection object is to set up and create a peer connection.

View the demo and source code form the below link:




RTCDataChannel API makes peer-to-peer exchange of arbitrary data, with low latency and high throughput.

View the demo and source code from the below link:


RTCDataChannel is available in Chrome, Safari, Firefox, Opera, and Samsung Internet
