The Observer is a bit different, it returns Future[Ack] for built-in back-pressure. We can Continue / Stop synchronously or asynchronously.

Project mention: Abstraction layers over the various JSON libraries? | reddit.com/r/scala | 2021-03-04
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.

Project mention: How do i read a csv file and parse it by , but ignore "ewf,wef" ? | reddit.com/r/scala | 2021-10-11Alpakka uses a state to track separators and quotes. Rather ugly code; https://github.com/akka/alpakka/blob/master/csv/src/main/scala/akka/stream/alpakka/csv/impl/CsvParser.scala If you think "," is hard think about "\n" where parsing the input line-by-line is fundamentally wrong ;)

Project mention: Scala newbie hoping to understand sttp with tapir testing. | reddit.com/r/scala | 2021-08-04
Assuming stub here is an SttpBackendStub, I can't see any machinery that would result in a NotFound when the whenRequestMatches isn't satisfied. So as /u/DrGrimmWall says, I think we need more information in order to be able to help.

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.

In this example, the code uses Play WS Standalone as a REST client to fetch JSON containing a UUID. Play WS has an asynchronous, non-blocking API based on Future, so you need to provide an ExecutionContext via Akka. That's all the boilerplate at the beginning of this example. Sometimes it will be done for you as when you use Play WS in the context of Play Framework. Nonetheless, you should be aware it has to happen somewhere.

Project mention: Stockholm Syndrome Escape Velocity (A Talk About Scala.js) | reddit.com/r/scala | 2021-01-25
You can see one example in https://github.com/raquo/Airstream/pull/60, you'll need to copy the PR code into your own project though (it doesn't touch Airstream internals so it's easy). If you search Laminar gitter room for "websocket" you'll find other third party websocket implementations too (not sure about specific examples)
