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.

Automerge 2.0
See also, Autosurgeon (with a 0.3.0 release today), which is a higher level API on top of Automerge for Rust:
I'm building a mobile app with a server backend, and I was looking for resources to build them in an offline-first way (since unlike on the browser, people expect to use apps offline, if they can, such as fitness or habit trackers).
I found the concept of conflict-free relational data types (CRDTS) interesting as it allows you to have fully offline experiences while also having a conflict-free syncing experience. I was looking for some good libraries and came across automerge [0] and yrs [1], but both had some rough APIs as they're primarily low-level Rust libraries that are wrapped by higher-level TypeScript APIs.
Autosurgeon wraps the low-level API of automerge to make it much more ergonomic, closer to the TypeScript experience, but in Rust of course. You can for example use `struct`s which autosurgeon will serialize and deserialize automatically, which is not present in base automerge, which focuses more on string keys and arbitrary values.
I am planning on using this together with Flutter and flutter_rust_bridge [2] in order to use this same Rust library everywhere. In this case, the server just becomes another (albeit more privileged) client.

What do you recommend for conflict-free replicated data type (CRDT) support in Rust?
Yes, the plan is to use PostgreSQL. I had a discussion with one of the devs in this ticket about the strategy for this.

Some key-value storage engines in Rust
In any case, my current plan is to use Automerge for the data handling itself (so I can easily do collaboration), but that crate doesn't handle on-disk storage. For this I need another solution, and a K/V store is well suited for this task.

Official /r/rust "Who's Hiring" thread for job-seekers and job-offerers [Rust 1.66]
15 years working in software, Rust has been my favourite language for the last 2. Recently completed a contract to prototype a distributed Tailscale-inspired VPN built on Ink and Switch's CRDT project automerge-rs.

You might not need a CRDT (Conflict-free Replicated Data Type)
Complex topic. There's a very easy-to-use CRDT library for Rust (automerge), while there isn't much support for operational transforms (although Aper is new to me, I have to check it out).

Testing CRDTs in Rust, From Theory to Practice
I've been watching automerge-rs like a hawk, because they seem to be the only CRDT implementation where you don't need a Mathematics master to understand how to use it. They've been working on a rewrite for the last two years, hopefully they'll do a new release soon.

Show HN: SyncedStore CRDT – build multiplayer collaborative apps for React / Vue
https://github.com/automerge/automerge-rs
By the way despite that particular repo (@localfirst/state) last being touched 6 months ago, Herb Caudill definitely seems still active in this space (I believe he's been working on other parts of this more recently -- e.g. ideas about authentication), and I think automerge development itself is quite active right now leading up to a 1.0 release which seems fairly imminent, for which a lot of fundamental work has been done, also coordinating with automerge-rs.

Automerge-Repo: A "batteries-included" toolkit for local-first applications
Nice, I use automerge with Rust via autosurgeon [0] which is their Rust wrapper, but looks like it hasn't been updated recently, any updates on that? I'm guessing with a small team that web support is taking priority right now, as I'm running this on my Rust client (technically Flutter but via the FFI package flutter_rust_bridge [1]) and server (via the Axum web server crate).

Automerge 2.0, CRDTs, and Local-first Software
Also take a look at autosurgeon, which wraps this Rust library (which is lower level) with a higher level API.

Automerge 2.0
diamond-types (for reference for others [0]) still only supports plain text, is that right? I was thinking of using it for more general use cases such as an offline habit tracker, which isn't text of course, but I was interested to hear more on the progress towards other data types such as generic JSON data.
Currently for this use case I've been using autosurgeon [1] so far which has a nice Rust API for structs, even if it might be slower than yjs (or yrs, its Rust implementation) or diamond-types.
