HN comment orderHey HN! This is a book I am working on to help de-mystify WebRTC. It is wonderful technology, but many find it hard to understand. Especially if you don't have a telephony background. Before this I worked on https://github.com/pion/webrtc and https://github.com/awslabs/amazon-kinesis-video-streams-webr... I wanted to share all my knowledge from working on these. ------ Come learn about the WebRTC specification and how all the protocols work in depth, not just a tour of the APIs. The book is completely Open Source…
WebRTC is lowkey one of the most underrated technologies out there, ESPECIALLY WebRTC data channels. WebRTC data channels are basically “UDP on the web” but they have lots of controls to change how reliable they are, so they can be used as TCP style connections as well. I still don’t fully understand why more people don’t use them over something like QUIC. (I think I’ve asked this question before here, but I wasn’t really satisfied with the answers) I sadly…
This is a really nice overview of the nuances of WebRTC. If you want to try this tech at a higher level, I maintain an experimental hobby project that attempts to abstract all the complicated parts of WebRTC into a simple API. Most importantly, it obviates the need to run your own signaling server by piggybacking on various public protocols like torrent trackers or IPFS to match peers. It's well-suited for quick projects/prototypes. https://github.com/dmotz/trystero/
