  • Server Stack Options for Scala

    If you want a mature REST API library, I recommend http4s. Be aware, though, that it’s based on purely-functional programming with Cats, cats-effect, and fs2, so if you’re not familiar with them or aren’t prepared to commit to the paradigm, the learning curve may be daunting, seem pointless, or both.
  • Sequential application of a constructor?

    See also cats-effect and fs2. cats-effect gives you your IO Monad (and IOApp to run it with on supported platforms). fs2 is the ecosystem’s streaming library, which is much more pervasive in functional Scala than in Haskell. For example, http4s and Doobie are both based on fs2.

    Most important/known: * https://http4s.org/ - an HTTP client/server * https://github.com/typelevel/fs2 - streaming * https://github.com/tpolecat/doobie - JDBC

    Scala devs are too busy wondering about free monads and F[Request[F] => Response[F]]. I am very pleased by http4s, Doobie, ScalaJS, and the whole ecosystem, really: https://http4s.org
  • http4s as a replacement for akka-http?
    6 projects | reddit.com/r/scala | 15 Sep 2022
    In reality, your performance issues will not be http4s, but something else. That being said, there are improvements that http4s can and is making, and I'm quite excited about the future 1.0 release, which has some important and fundamental performance improvements already, like a a 125% performance improvement on the plaintext benchmark from https://github.com/http4s/http4s/pull/6091 - and finally, yes, akka-http does have very good performance, but you can also get good performance out of http4s.

    http4s for REST services.
  • Scala became Typelevel/Zio only ecosystem?

    This is a long list of misunderstandings I don’t have the patience to unpack. Instead, let me refer you to the links in my top comment in the thread, then suggest you learn at least http4s, a purely-functional web service library that’s been used in production for a decade or so now.
  • Pleasant to use Scala libraries
    5 projects | reddit.com/r/scala | 6 Jul 2022
    I would say http4s and Doobie. Both are pure FP libraries in the Typelevel ecosystem. Both are exceptionally clear, extremely reliable, extremely pleasant to use… I like to point out http4s, in particular, is primarily a collection of types modeling the relevant RFCs. What behavior it has comes overwhelmingly from the underlying Cats, cats-effect, and fs2 libraries. This reflects the generality of those underlying libraries and the intense focus of the http4s team. The same applies to Rob Norris and Doobie, which tames JDBC as well as it can be tamed, IMO.

    The most popular nowadays are - I guess - akka-http and http4s. You can also use Play if you don't want to start from scratch but prefer a framework-based approach.
  • Scala Http Framework

    If you want something more powerful, pure-functional and you need to do complex, concurrency-heavy operations, have a look at http4s: https://http4s.org/
