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.
How to get started?

http4s is a Typelevel project, and therefore falls into the "program in Scala as if it were Haskell" category. Many people find this off-putting, but honestly, I think with the resources listed above, this is the option at the best intersection of "mature" and "well-documented" available in Scala. The reason it's off-putting to many people is that Haskell-style pure FP isn't mainstream, so it isn't so much a matter of learning a new technology as it is a matter of learning a new paradigm, which necessarily means surfacing and unlearning things you already know, and perhaps confronting the uncomfortable feeling that things you thought were "fundamental," "have to be that way," aren't, and don't. I personally found this process liberating. But not everyone does.
Server Stack Options for Scala
4 projects | /r/scala | 13 Feb 2023
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?
2 projects | /r/scala | 21 Jan 2023
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.

Relative popularity of programming languages on Hacker News

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 | /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.
Is Scala a good choice for a data intensive web backend?

http4s for REST services.
Scala became Typelevel/Zio only ecosystem?
4 projects | /r/scala | 6 Aug 2022
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 | /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.5 projects | /r/scala | 6 Jul 2022
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.

What's the state of server-side frameworks with Kotlin support today for small teams?
6 projects | /r/Kotlin | 17 Apr 2023
Explicitly so:6 projects | /r/Kotlin | 17 Apr 2023
Personally, I like vertx, it is modular and you can pick and choose what you need. It also has support for kotlin coroutines, https://vertx.io/, https://github.com/vert-x3/vertx-examples/tree/4.x/kotlin-examples
Anything close beam/otp for other languages?
7 projects | /r/elixir | 7 Apr 2023
I really like Eclipse Vert.x... As both an Erlang dev and Java dev, it's a great synergy and soon to have support for Virtual Threads similar to BEAM.
Go doesn’t do any magical stuff and I love that
8 projects | /r/golang | 12 Mar 2023
There are many lean, popular, non-magical libraries in Java land. (https://quarkus.io/, https://vertx.io/, etc). Spring is a monster 😱. Its like comparing Kubernetes (written in Go) with some lean framework in another lang.
