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.
Typeclasses explained in Java
3 projects | dev.to | 27 Jul 2022
If I managed to gain you interest you can take a look at one of the following libraries like cats, scalaz for scala and vavr for java which contain type class definitions and implementations for common types.
In Search of the Best Functional Programming Back-End: 2021 Update
4 projects | dev.to | 24 Jan 2021
I’ve specifically had 2 job offers internally at my company because of this language. First with Cats and Scalaz and now with ZIO, Scala has taken the best parts of Haskell, the best parts of Scala, and made it really nice to work with. You can barely see the OOP leftovers.
Is it possible to get runnable generated scala code from a macro (chminey to be specific)?
2 projects | reddit.com/r/scala | 20 Jan 2022
I want to upgrade one project to Scala 3.1, but I'm using the macro heavy chimney (https://github.com/scalalandio/chimney) to reduce the boilerplate, which is not available for Scala 3 yet. My idea was to copy and paste the code that chimney generates on 2.13, and after that uncomment the uses of chimney for now.
From ES6 to Scala: Basics
9 projects | news.ycombinator.com | 20 Jan 2022
In my $dayjob we originally used Scala, but I pushed for a couple of new services to be written in TypeScript/Node as it was really hard to hire Scala developers. I'd say it worked well, we even took a somewhat functional approach to building things. We tried fp-ts but that was a bit hardcore (when you are trying to hire TypeScript developers who don't know functional programming), so just built Either and Option types which provided 99% of what we needed.
There are still a few things I miss though:
* Pattern matching and exhaustive checking. Using a switch statement it is possible to define a function that can emulate the compile-time exhaustive checking, but it's still rather weak compared to what you can do in Scala.
* Implicits. Being able to define something that can convert say a UUID to a String or vice versa automatically just feels like magic, especially when dealing with data from third party systems.
* Compiler macros and metaprogramming. It enables tools like Chimney (https://scalalandio.github.io/chimney/) to be built, which I don't think are possible with TypeScript right now.
Scala Type Classes from Scratch

Converting between these classes can add some boilerplate, but luckily there are libraries like https://github.com/scalalandio/chimney that make it much easier.
Ideas for a Scala 3 MapStruct library?
5 projects | reddit.com/r/scala | 1 May 2021
Hi! Are you aware of https://github.com/scalalandio/chimney? I think that's what you are trying to do. Sorry if I misunderstand your message.
Circe is driving me insane
1 project | reddit.com/r/scala | 16 Jan 2021
You might think that this looks like more boilerplate, however: 1. You only have to write these conversions once. 2. There are libraries that makes this precise case easier, such as https://github.com/scalalandio/chimney
