  • GitHub repo skunk

    A data access library for Scala + Postgres.

    Project mention: Zio / Zionomicon : is it worth it ? | reddit.com/r/scala | 2021-11-01

    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.

  • GitHub repo natchez

    functional tracing for cats

    Project mention: The wonder of context functions | dev.to | 2021-12-21

    Regarding real-world uses of this concept, I used it today to put natchez tracing in my http4s project. While the project is still small, I was shocked at the lack of invasiveness of this approach compared to usage of Kleisli to achieve the same effect.

    Project mention: A naive question about modeling task | reddit.com/r/scala | 2021-08-23

    In pure FP terms, the system I'm aware of for this is fs2-es for the Typelevel ecosystem. Note that I haven't actually used it. I'm just aware that it exists.
