The product I work on uses Tiptap pretty heavily, so I’ve looked into how I might implement collaborative editing just with Elixir.

Tiptap uses Yjs data structures for collaborative documents. However there’s no Elixir client so I was thinking of trying to use the y-crdt Rust package via rustler. I’d be interested to hear if you can get something like that to work.

Tiptap also has their own hosted backend for collaboration and includes live cursors/highlighting and support for threads/comments.

Haven’t used TipTap, but check out this example project: GitHub - sheharyarn/collab

Just to keep you updated, I decided to spin up a separate server for HocusPocus. Mostly because I’m a newbie and there was too much skill-issue to overcome.

So the HocusPocus server is using my Elixir server for auth, loading / storing docs.

I do not thing you need all this miss you could implement the y-websocket server by checking the example and it is easy to implement.
