The WebRTC brand has been gaining a lot of traction lately as more people are understanding its potential. The W3C and IETF have proposed various standards to enable real-time, peer-to-peer communication on the web, and Google has been spearheading the implementation with its Chrome browser.

With all this excitement, you may be wondering where you can get started with WebRTC. If so, you've come to the right place.

In this blog post, we'll take a comprehensive look at the WebRTC samples repository on GitHub. We'll walk you through the different types of samples that are available in the repo. By the end of this post, you should have a good idea to get started with WebRTC.

However, if you don't want to go through all the hassle of WebRTC and want a faster approach, try Dyte and go live in mins not months.

Different WebRTC Samples on GitHub

These samples are intended to illustrate the various features of WebRTC in the simplest way possible. Various viewport sizes are supported by all live demos.

Data channels, peer connections, and getUserMedia are canonical demos here. Let’s have a look at each of them in detail.


The first and most important WebRTC API is getUserMedia(). This API allows web applications to access the user's microphone and camera. It is available in all modern browsers.


WebRTC allows you to choose which devices to use for communication. You can select the audio input and output devices such as microphones, speakers, and headphones. You can also select video input devices such as webcams and digital camcorders.

Stream Capture

WebRTC provides APIs for capturing media streams from WebRTC-compatible devices. The MediaStream API represents synchronized streams of media content. The getUserMedia() method prompts the user for permission to access the specified media types (audio and/or video), and if the user grants permission, returns a MediaStream object containing the requested types of media tracks (specified by kind).

RTCPeer Connection

WebRTC uses the RTCPeerConnection API to set up real-time media communications between web browsers, typically involving audio and video streaming.

The RTCDataChannel API allows two connected peers to share arbitrary data. Data channels are available in Chrome and Firefox.

Video Chat

A typical WebRTC application has two components: a client application running in the browser and a server application running on a web server. The client application needs to know how to connect to the server so that it can exchange signaling information with other clients (peers). Once two peers are connected, they can use the RTCPeerConnection API to communicate directly with each other.

Insertable Streams

Insertable streams allow you to add your own audio or video tracks to an existing media stream. This can be used, for example, to add subtitles or watermarks to a video chat. The insertable streams API is available in Chrome and Firefox.

Final Verdict!

The GitHub repository for WebRTC is a great resource for developers who want to get started with the protocol. The samples provide a comprehensive guide to all aspects of WebRTC development, from basic tutorials to more advanced features. If you're looking to get started with real-time communication applications, the GitHub repo is a great place to start.
