Question: why server need a centralized doc ? about y-websocket

[dmonad]

Hi @zlv-thisF ,

Yjs is network agnostic. That means it works with any communication protocol. You just need some way of propagating all changes to all clients.

Yjs has many network providers to allow shared editing using webrtc, websocket, dat, and for v12 there also exist modules for IPFS and XMPP. This is explained in the README. Let me know if that was unclear.

For many applications, it is still advantageous to have servers. Servers tend to be more reliable than p2p WebRTC connections. Furthermore, many applications want to index the data on a server anyway. The big advantage of Yjs is that you can scale the servers in a distributed manner. Option 1 describes a decentralized approach, that just uses PubSub to share document updates. The main advantage of Yjs over centralized approaches like ShareDB is that the whole system doesn't break if one server fails. You can simply start another server doing conflict resolution.

I'm gonna close this issue for now, but let me know if you need more clarification.
