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.

I have decided to connect my future with Scala (if possible), need little advice
Functional Event-Driven Architecture for the ZIO ecosystem. I hear Zionomicon is evolving again, and that's good news. But there's literally years of more work to do.

Udemy vs Rock the JVM for Cats, Cats Effect, and FS2
https://leanpub.com/feda, This book also by Gabriel vlope is another good one. I bought them together on offer in december. Functional event driven architecture. It done in scala 3

Any FS2 + Kafka github projects for reference?
Personally, I would go for https://github.com/gvolpe/trading

If you're using http4s, don't use ZIO. Yes, ZIO has an interop-cats module, so you can do this. But using http4s means you're working in the conceptual framework the Typelevel ecosystem is based on (and what interop-cats does can be characterized as "describe ZIO's implementation in those terms, so the Typelevel ecosystem can make heads or tails of it.") This is essentially all cost and no benefit: you can't avoid understanding the Typelevel ecosystem if you use http4s (at least, no more than you can by using cats-effect), and you don't get any of the value proposition of ZIO (interop-cats gives you Typelevel typeclass instances for the RIO type alias, which means your error channel is rooted in Throwable, and you're faced with the most complex part of the ZIO ecosystem: ZLayer, which the Typelevel ecosystem doesn't use and doesn't need). Finally the ZIO ecosystem is still quite immature, and this brings us to documentation. There is not (yet!) anything comparable to:
- Using FS2 alongside ZIO?
-
Friction-less scala - Tell us what is causing friction in your day-to-day life with Scala
These are necessarily oversimplifications. In particular, the ZIO ecosystem offers the relevant instances of cats-effect typeclasses to support use of the ZIO type in the cats-effect ecosystem.

Why Typelevel hates ZIO?
However, ZIO continues to offer cats-effect type classes and I certainly have no doubt cats-effect 3 continues to benefit from John's contributions. Furthermore, I likewise don't doubt the value of the ZIO ecosystem generally, and John's success in building the ZIO community speaks for itself. I personally have chosen to remain closer to the other, let's say "classical," pure FP ecosystems, partially for historical (or, if you prefer, "sunk cost") reasons, but partially because I'm satisfied the value of the Haskell/Typelevel/PureScript/fp-ts/etc. interplay warrants it.

Is it possible to use cats' monad transformers (OptionT, EitherT) with an effect type (F) that has >1 type parameter?
It seems that zio/interop-cats faces a similar issue.
What are some alternatives?
