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.

Local-first software: You own your data, in spite of the cloud (2019)
This article has been quite the inspiration for many projects and progress on this front. I think we're seeing more and more developments around CRDTs and local-first frameworks / applications.
I'm working on a few projects in this area:
- https://www.typecell.org - Notion meets Notebook-style live programming for TypeScript / React
- https://www.blocknotejs.org - a rich text editor built on TipTap / Prosemirror that supports Yjs for local-first collaboration
- https://syncedstore.org - a wrapper around Yjs for easier development
In my experience so far, some things get more complicated when building a local-first application, and some things get a lot easier. What gets easier is that once you've modeled and implemented the data-layer (which does require you to rethink / unlearn a few principles), you don't need to worry about data-fetching, errors etc. as much as in a regular "API-based" app.
Another interesting video I recommend on this topic is about Linear's "Sync Engine" which employs some of the local-first techniques as well: https://www.youtube.com/watch?v=Wo2m3jaJixU

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 [1] (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 [2].
Automerge has a bit friendlier "Immer style" [3] API. I'm not too familiar with @localfirst/state, but it seems to add a Redux style API on top of Automerge.
My approach with SyncedStore was really to provide an API on top of Yjs that's as simple as possible to use in React / Vue / Svelte or plain JS app. I.e.: only use a single React Hook to observe changes, and use regular Javascript assigments to update values. The API is inspired mostly by Reactive Programming libraries such as MobX [4] (from the same author as Immer).
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!

Web Applications from the Future: A Database in the Browser
I’m exploring the ideas (an easy to use framework to build local-first [1] 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.

Episode 24/13: Native Signals, Details on Angular/Wiz, Alan Agius on the Angular CLI
Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/
Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity".
Observables otoh say "fuck it, I'm mutating everything, do what you want with it".
