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  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 . 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.

Show HN: SyncedStore CRDT – build multiplayer collaborative apps for React / Vue

Hi! Great questions :)
First of all, SyncedStore does not implement any CRDT algorithms. Credits for this go to Yjs  (and its author Kevin), which it uses as underlying CRDT.
Yjs and Automerge are (afaik) the two most commonly used CRDT implementations. Both have their pros and cons, but Yjs has focused a lot on performance .
Automerge has a bit friendlier "Immer style"  API. I'm not too familiar with @localfirst/state, but it seems to add a Redux style API on top of Automerge.
Hope you're still following along :) Maybe it helps to compare the TODO-MVC applications, as both SyncedStore (https://github.com/YousefED/SyncedStore/tree/main/examples) and @localfirst/state (https://github.com/local-first-web/state/tree/main/examples/...) have implemented these as examples!

I’m exploring the ideas (an easy to use framework to build local-first  apps) in my library Reactive-CRDT (https://github.com/yousefed/reactive-crdt). Feedback welcome!
All credit for the underlying tech to YJS, which has been amazing as mentioned by others in this thread.
