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.

Example of building web apis (functionally) in Scala
https://github.com/devinsideyou/tagless-final Full disclosure: it's mine. Note: there are 2 projects in this directory and so `todo` is the one you want.

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?

Grasping the concepts and getting them down to earth
Most important/known: * https://http4s.org/ - an HTTP client/server * https://github.com/typelevel/fs2 - streaming * https://github.com/tpolecat/doobie - JDBC

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.

Is “Functional Programming in Scala” 1st edition still relevant?
Finally, the last chapter has been rewritten to be based on some of the main design ideas from FS2 (https://fs2.io), which I hope will be more approachable than the 1st edition.

FS2 stream doesn't work as I expect it to
Just to clarify, is your doubt about the meaning of the api, or do you think you have found a bug? In either case, you can also open a Github discussion https://github.com/typelevel/fs2/discussions.

How to update and access state that needs to be shared across multiple API endpoints with FP?
Another more reactive solution would to use signals, as in FPR sinal network. fs2 implements this very nicely here https://github.com/typelevel/fs2/blob/8b285a6b54c63d43ed6aa3bb91365652035c90e5/core/shared/src/main/scala/fs2/concurrent/Signal.scala

Introducing effects systems S.A. ZIO at work?
Assuming the bug mentioned here is https://github.com/typelevel/fs2/issues/2568, we came up with a partial fix in a day (https://github.com/typelevel/fs2/pull/2569) and a complete fix in 2 days: https://github.com/typelevel/fs2/pull/2572. Note the original bug was opened on a Saturday. :)
