Overview

In this module, you’ll learn how to build an web application to establish a peer-to-peer video call via WebRTC. Along the way you’ll also learn how to use the WebRTC APIs and build a signaling server using Node.js.

What you’ll learn

At the end of this module, you will learn about the following concepts as they relate to WebRTC:

• MediaStream APIs to access the media streams from local cameras and microphones.
• Establish a peer-to-peer connection between each of the browsers via RTCPeerConnection APIs.
• Exchanging messages, such as audio and video streams with RTCDataChannel APIs.
• Screensharing using WebRTC's Get Display Media API.
• Building a simple signaling server to exchange media data between peers.
