Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

5000x Faster CRDTs: An Adventure in Optimization
Yes, xray was abandoned and teletype is written in JS.
I understand your point and as a researcher and engineer I know your feeling. I took some cautions by using "Some optimizations". I value engineering as much as research and I'm bothered when I heard any side telling the other side that their work is worthless. Your work and the work of Kevin Jahns are very valuable and could improve the way that researchers and engineers do benchmarks.
This is still hard for me to determine when position-based list CRDT (Logoot, LogootSPlit, ...) are better than tombstone-based list CRDT (RGA, RgaSplit, Yata, ...). It could be worth to assess that.
3 year ago I started an update of LogootSplit. The new CRDT is named Dotted LogootSplit [1] and enables delta-synchronizations. The work is not finished: I had other priorities such as writing my thesis... I have to perform some benchmark. However I'm more interested in the hypothetical advantages of Dotted LogootSplit regarding synchronization over unreliable networks. From an engineering point-of-view, I'm using a partially-persistent-capable AVL tree [2]. Eventually I would like to switch to a partially-persistent-capable b-tree. Unfortunately writing a paper is very time consuming, and time is missing.
I still stick with JS/TS because in my viewpoint Wasm is not mature yet. Ideally, I would like to use a language that compiles both to JS and Wasm. Several years ago I welcomed Rust with a lot of enthusiasm. Now I'm doubtful about Rust due to the inherent complexity of the language.

Flutter offline
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).

Best local database that works on all platforms including web?
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.

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.

Evan Wallace CRDT Algorithms
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

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.
