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
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:
-
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.

Building React Components Using Unions in TypeScript
Naturally I’d recommend using a better language such as ReScript or Elm or PureScript or F#‘s Fable + Elmish, but “React” is the king right now and people perceive TypeScript as “less risky” for jobs/hiring, so here we are.

purerl - Integrating PureScript into Elixir projects
PureScript is a Haskell-like language aimed at providing an alternative to TypeScript for statically typed programming in the JavaScript space. I highly recommend taking a look at PureScript for your compile-to-JavaScript needs outside of the use case we'll be talking about in this post.
What are some alternatives?
fp-ts - Functional programming in TypeScript
reason - Simple, fast & type safe code that leverages the JavaScript & OCaml ecosystems
elm-reactor
Elm - Compiler for Elm, a functional language for reliable webapps.
rescript-compiler - The compiler for ReScript.
Idris2 - A purely functional programming language with first class types
liquidhaskell - Liquid Types For Haskell
polysemy - :gemini: higher-order, no-boilerplate monads
stylish-haskell - Haskell code prettifier [Moved to: https://github.com/haskell/stylish-haskell]
haskell-names - Haskell suite library for name resolution
from-typescript-to-rescript - Frontend of https://Inhyped.com written in TypeScript and rewritten in ReScript
reflex - Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse.
