I’ve done a lot of voice WebRTC with elixir. Typically, the media path for WebRTC is from browser to browser, and the server is not included in the media path unless you need to have the server in the middle of the media path. Phoenix channels are great for the WebRTC signalling portion to setup the media path. I have not used data channels yet, but can’t imagine that they are much different than voice or video.
If you need to anchor the media path on the server, your going to have some difficulties with Elixir/Erlang. Current browsers require that the WebRTC media path use DTLS (TLS over UDP). The last time I checked (6 months ago), there was NO support for DTLS in erlang.
I have a simple Phoenix WebRTC demo project on github you may want to checkout.
