Hindsight is a free and open-source retrospective board
No back-end. Data is shared via WebRTC directly between connected browsers. I'm using Yjs to help me with that.

CRDTs: A Beginner's overview for building a collaborative app
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.

CRDTs make multiplayer text editing part of Zed's DNA
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
- Maintaining Referential Integrity During Insertions And Deletions

Show HN: Yboard is a multiplayer desktop-like workspace based on CRDT
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.

Should I Move From PHP to Node/Express?
For instance, practicing "local first web" using automerge with all it's Distributed Persistence Primitives on CRDT's and Vector Clocks - i.e. when the Browser View is treated like a Database replica, essentially; or adopting a real data mapper that's giving you an API from your database Schema, using Prisma or Hasura... or even implementing a custom codegenereted one, as a babel plugin, on top of TSED and Micro-ORM.

And about conflict --as already mentioned in comments-- CRDTs is the way to go here. Automerge is an implementation you may want to look into.
