hyperhyperspace-core VS svelt-yjs

Not all CRDT libraries focus on text editing. For example, I'm working on a Byzantine fault tolerant general-purpose data sync library loosely based on CRDTs: https://www.hyperhyperspace.org

I'm finding it painfully difficult but it is evolving steadily.

I'm thinking there's an interesting parallel between my browser-based p2p project [1] and cloudflare workers / DurableObjects. Instead of DurableObjects, we got HashedObjects [2], and instead of workers running on an edge network somewhere, we got in-browser p2p nodes running a browser-to-browser mesh network.

I agree with the author on the merits of the file abstraction, but I think the concept should be updated for networked devices. We need file formats that support both offline usage and seamless sync over the network.

For example, here I use a merkle DAG-based file format to represent CRDT-like types:

The resulting abstraction can be universally looked up using a hash (or short sequence of words), can be modified offline and synchronized flawlessly. It's still WIP (for example, you still can't export it to an actual file, hehe).

> I've been kicking around the idea of writing a CRDT-based editor using this model.

I got around to creating a data layer (p2p, browser-based, CRDT-backed) for something like this:

I'd be interested in collaborating on your editor

I'm working on it, Ben [1].

Believe me, it is not easy thing to do.

Look at Hyper Hyper Space!

https://github.com/hyperhyperspace/hyperhyperspace-core

Its goals are similar, the approach is more pragmatic (p2p data layer using standard web browsers and webrtc).

There are also some great implementations based on Yjs like this one svelt-yjs I prefer Yjs to automerge

Excited to check this out!!

I’ve got experience with this stuff, count me in! Check out svelt-yjs[0]. It makes complex CRDT apps trivial. Websockets or P2P WebRTC in a few lines. I’ve got a live collab Svelte REPL using Monaco almost complete. It uses Postgres via Supabase for auth / row level security / saving and sharing Apps you make.

Heck, plug yjs into this Svelte based notion style block editor[1] and you’re more than halfway done in an evening.
