Top 12 Scala Typelevel Projects

I know that libraries like Scodec and shapeless were rewritten practically from scratch for Scala 3, taking advantage of the next syntax and internals, as well as protoquill - a Scala 3 implementation of Quill.

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/

Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

Developer removing a library integration due to above politics

The Observer is a bit different, it returns Future[Ack] for built-in back-pressure. We can Continue / Stop synchronously or asynchronously.
-
You want either a refined type, a newtype, or if you are in Scala 3 an opaque type.

Project mention: Monocle 3 release candidate - a super useful and simple library for optics with poetic api | reddit.com/r/scala | 2021-06-01
See example https://www.optics.dev/Monocle/

The libraries doobie and skunk are more closely associated with cats. They both use cats-effect and fs2 for implementing database connectiona and input-output operations. The doobie library is a wrapper on JDBC, and as such is compatible with many DBMS, such as MySQL, PostgreSQL, H2, Oracle... Whereas skunk is specific to PostgreSQL, and is based on using the server protocol of that database.

There’s Spotted Leopards, which isn’t intended to be used but is an experiment in “what if Cats, but Scala 3 only?”
