  • How to decouple logic from Scala future?
    1 project | /r/scala | 14 Dec 2022
    Here's an example from a library I've used: https://github.com/sksamuel/elastic4s/blob/master/elastic4s-core/src/main/scala/com/sksamuel/elastic4s/Executor.scala. Then you can provide your own Executor implementation and it will be used instead of the FutureExecutor. You can check out the top level of that repo to see how much complexity this introduces.
  • Abstraction layers over the various JSON libraries?
    4 projects | /r/scala | 4 Mar 2021
    Seems like the accepted solution is to have a separate subproject for each of the ~5 major json libraries. For example see elastic4s (elastic4s-jackson, elastic4s-circe, ...) or akka-http-json.
