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.

Autosurgeon 0.3.0, use conflict-free replicated data types (CRDTs) to build offline-first apps with an easy-to-use API based on Automerge

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.

Comparing React state tools: Mutative vs. Immer vs. reducers
Immer is a lightweight package that simplifies working with immutable states. Immutable data structures ensure efficient data change detection, making it easier to track modifications. Additionally, they enable cost-effective cloning by sharing unchanged parts of a data tree in memory.

Show HN: Cami.js – A No Build, Web Component Based Reactive Framework
```
It looks like it’s mutating, but both the reducers and update() uses immer* under the hood, so we still respect immutability under the hood.
Cami supports redux devtools so you can use that for time-travel debugging too!

Making Sense of React Server Components
I heard that immutability libraries like immer.js [0] help with this. Anyone go this way and had good success? Is this 'the way'?

How We Fixed Performance With JS Object Variable Mutation
So, that's what we built, and we built it in the most obvious way — using JavaScript Proxy objects to track mutations and reflect those changes across Appsmith’s framework. Initially things looked good — it worked, aside from a few hacks to make some data types work with map and set, and we were following the example of other projects that had similar requirements. If it was good enough for them, it should be good enough for us, right?

The sword refers to immer, the faster and stronger immutable data js tool limu stable version released!
But is immer really the ultimate answer? The performance problem of immer is more prominent in large arrays and deep-level object scenarios. See this issue description, many authors in the community began to try to make breakthroughs, and noticed that structura and mutative, I found that it is indeed many times faster than immer as they said, but it still fails to solve the problem of both fast speed and good development experience. I will analyze the two issues in detail below.

Ramda: A practical functional library for JavaScript programmers
I like immer for this kind of thing: https://github.com/immerjs/immer
It gives you immutable updates without getting bogged down in FP abstractions.

Why my variable is being mutated if I make any changes to my data ?
I've always been a huge fan of immer for these case. For your code, it would simply turn into setGridData((prev) => produce(prev, draft => applyChanges(changes, draft)) but I recommend you go over their documentation to fully understand how it works

Is there a better way to do read-only types
If you're trying to make things actually immutable, Object.freeze and deep copies can clutter things up pretty good, have you considered using something like immer? (https://immerjs.github.io/immer/)
