Chapter 3. Creating a Basic WebRTC Application

The first step of any WebRTC application is to create an RTCPeerConnection. Creating a successful RTCPeerConnection will require an understanding of the inner workings of how a browser creates peer connections. Firstly, in this chapter, we will lay the groundwork to understand the internals of WebRTC. Then we will utilize this knowledge to create a basic WebRTC video chat application.

In this chapter, we will cover the following topics:

• Understanding UDP transport and real-time transfer
• Signaling and negotiating with other users locally
• Finding other users on the Web and NAT traversal
• Creating an RTCPeerConnection
