WebRTC for the rest of us
(Or more like WebRTC ... how does it, even?)

This is me
So WebRTC ...
RTC = Real Time Communication
The goal of WebRTC
Low latency peer-to-peer video, audio, and data
But it's not just for browsers!
And it's not just for video chat!
It's not just for video 🤷♂️
So how does it work, actually?
ICE Candidate Exchange
Important Terms
Signaling Server
SDP - Session Description Protocol
STUN - Session Traversal Utilities for NAT
TURN - Traversal Using Relays around NAT
ICE - Interactivity Connection Establishment
ICE Candidate
DTLS - Datagram Transport Layer Security
(S)RTP - Real Time Protocol
RTCP - Real Time Control Protocol
For our STUN/TURN server ...
Open source, all things WebRTC in Go
Let's write some code!

WebRTC
WebRTC is a collection of protocols that grants computers the power to share data and real time media without the intervention of a server. Well that’s kind of a lie. We still need servers to help establish the connection. But it’s still pretty cool! I don’t suppose you’ve ever used Zoom or Google Hangouts before have you? Well, those use WebRTC too. What if we could build our own video chat? Well, that’s what we’re gonna do. We will build our very own WebRTC video chat app! Along the way, we’ll learn about all the moving pieces involved in establishing peer to peer WebRTC connections. We’ll talk about STUN, TURN, ICE, and a mouthful of other fun acronyms. The build will focus on the front end client, the server they use to introduce themselves to each other, and we’ll deploy open source solutions for anything else we need.
