When I was last looking at the libdweb stuff they didn't have WebRTC support working in the service workers to let you use it from a protocol handler (and they somehow didn't even consider that important as they insisted no one would even want to use WebRTC, which made no sense to me); did they eventually fix that so you could do WebTorrent?
You can implement your own protocol + handler with the functionality exposed by the library as far as I understood.
It doesn't really matter anyway since you have access anything firefox can do with webextensions experiments, which was required since libdeweb isn't a part of firefox(and won't be anytime soon because AFAIK most people who were working it has been laid off) and to run experiments you need firefox nightly.
Pretty much this. The code runs as an extension - it registers the protocol handler in the extension's background script. That means the code for webrtc has no need to run in a service worker.
OK, so as I don't actually do much in-browser development, and because this was also two years ago, "of course" I managed to get the terminology wrong: the issue was that WebRTC wasn't supported in a "WebExtension" (not a "service worker", which happened to be the subject of a massive thread I was reading a few weeks ago on WebRTC not working there either).
Here's the bug I had referred to the libdweb person at the time in November of 2018 (due to comment #2):
> RTCPeerConnection.createOffer doesn nothing in WebExtension background script
Which was supposedly fixed? I'm honestly a bit concerned still, though, as this bug slowly got dragged from being about createOffer to being about permissions dialogs for audio/video, and it kind of sounds like there's some weird thing where a "foreground page" has to vouch for the extension, which shouldn't be required. Everyone who works on WebRTC stuff in browsers conflates it all with getUserMedia, but all of us distributed web people just want peer-to-peer data channels :/. I take it this is actually fixed then, and you can now use WebRTC in this context?
