sharedb VS automerge

Sure! Not sure about rust but I wrote this several years ago: https://github.com/share/sharedb (though now other people maintain it)

This is called Operational Transformation, and there are a few libraries to help with it. One that looks fairly mature is https://github.com/share/sharedb

one that sort of fell by the wayside when Meteor and Ember got popular, was/is Derby.js/ShareDB. https://github.com/derbyjs/derby https://derbyjs.com/ https://github.com/share/sharedb

The LiveView lead resurgence in server side rendering is exciting. Does anyone have any insight as to why ShareDB never really took off?

Rather than implementing your own you might be able to use a library like ShareDB. I think there was another one out there built on the open-sourced Google Wave code, but I don't remember the name.

I'm not aware of any usable CRDT implementations for Dart, my plan is to use the flutter_rust_bridge to make use of automerge v2, which is a full CRDT implementation written in Rust that has the advantage of having a very simple API to work with (basically a key/value store).

Yes. I asked the devs about ideas for this in this ticket and got an interesting response. It's aimed towards server-side handling, but the same ideas apply to local storage as well.

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.

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

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.
