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.

Ask HN: What are some of the most elegant codebases in your favorite language?
fs2 (reactive streaming, https://github.com/typelevel/fs2) written in Scala. It shows how nicely things can compose in a typesafe way if the language supports it.
And then, the opposite is Monix (https://monix.io/). It's also about reactive streaming and the API is great, but the inner code is ugly because it sacrifices readability/composability for performance.

The Great Concurrency Smackdown: ZIO versus JDK by John A. De Goes
Recently, CE3 has had similar issues reported across multiple repositories, almost an epidemic of reports!

Parallel streaming in Haskell: Part 1 – Fast, efficient, and fun
Thanks for the explanation!
So it's pull based and not push based like most other streams lib.
Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).
https://en.wikipedia.org/wiki/Iteratee
Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

Should I Move From PHP to Node/Express?
On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

Is Scala a good choice for a data intensive web backend?
fs2 for streaming.

ScalablyTyped publishes Scala 3 support
As of very recently, we're using ScalablyTyped in our fs2-io cross build for node. https://github.com/typelevel/fs2/pull/2453

Improving akka http code
In that case, it's best to keep different streaming libraries separate, in their own little "worlds". fs2 + cats has Queues for this purpose https://fs2.io/#/concurrency-primitives. Future has the Promise abstraction.

Scala 3 is here!
ScalaZ was changed to cats-effect. For streaming, look at fs2. Cats-effect 3 cleans up a lot of the library, but as with any code it can be clean or messy depending on the dev

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

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.

And about conflict --as already mentioned in comments-- CRDTs is the way to go here. Automerge is an implementation you may want to look into.
