Documentation about popspace

[a-type]

Yeah since this isn't actually public source yet, a lot of the docs are very casual 😄

But I can start answering some questions -

• Twilio: could absolutely be replaced by a different WebRTC provider! For groups of 4 or more, it's best to use a service provider which has SFU media servers like Twilio, 100ms, Agora, or self-hosted LiveKit. For small groups you might get by with peer-to-peer WebRTC. I'm actually working on some tech which can help make the media service provider more flexible, but it's not ready for public open-source quite yet (just started this week). Once it's mature enough I hope it can be ported to Tilde.
• For message protocol, due to the move-fast way we developed the app, there are quite a large number of messages for different events. Documenting them will take some time but I hope I can carve that out before we go public with the source or shortly after.
• We use Prisma as our database layer, but we utilize some Postgres-specific features in limited ways. Things like Json column types, views, sub-schemas, triggers, and functions would need to be ported correctly, and these are not managed by Prisma's migration system.
• S3 could maybe be eliminated, but the benefits are pretty important in terms of how the app can scale. With local files you'll run out of disk space unexpectedly unless your hosting infrastructure can scale your mounted volumes up for you. But it could be done.
