yjs VS pacman-backup

No back-end. Data is shared via WebRTC directly between connected browsers. I'm using Yjs to help me with that.

also there is this Javascript library that implements Conflict Resistant Data Types

There are a lot of implementations of CRDTs out there. In JavaScript, for instance, we have Y.js (https://github.com/yjs/yjs) and automerge (https://github.com/automerge/automerge). There’s also a Y.js demo (https://demos.yjs.dev/prosemirror/prosemirror.html) that allows you to play around with them and have your own collaborative app running in just a few seconds. All messages are exchange via webRTC and manages the state via CRDTs. This can be a great sandbox to understand how CRDTs work and see.

Yjs is being quite heavily used in the industry[1], and being researched for even more companies. There are also demos showing how to integrate it with an existing rich text editors[2]. If you have some ideas about the missing parts, you could also open topic on discuss.yjs.dev - the documentation page (https://docs.yjs.dev) has tons of useful links.

Re. other purpose projects - Yjs/Yrs main target are sequential data structures (text, arrays), but it also has support for maps and xml-like elements. In general you can build most data structures with it. I agree that it would be nice to have some other applications in demos though.

Anyone unsure of what a CRDT is, this is the perfect intro: https://www.inkandswitch.com/peritext/

The two most widely used CRDT implementations (combining JSON like general purpose types and rich text editing types) are:

- Automerge https://github.com/automerge/automerge

- Yjs https://github.com/yjs/yjs

I've always been curious about real-time multiplayer user interfaces.

When I found out about CRDTs and Yjs[1] I thought they could serve as a solid base for a project like that.

So I built this pretty simple desktop-like UI (heavily inspired by lifeat.io) and used Yjs to replicate the whole UI state among multiple peers, creating the experience of a unique interface.

So I built my own tool pacman-backup that allows exporting the cache to a usb drive, and to emulate a simple pacman server that you can run inside the local network.
