How to write microservices in Scala without Akka

on YouTube ↗41m

" summary

Argues that Akka can be avoided by defining endpoints with Tapir, generating Swagger docs automatically, and swapping the backend from Akka HTTP to Netty so the code returns typed Tapir endpoints instead of Akka routes, removing the need for an actor system and relying on Scala execution contexts and Futures. Demonstrates chunked file upload implemented with Akka Streams and an alternative using ZIO streams, shows a Tapir HTTP client without actor system, and highlights Akka’s license change (free under ~25B revenue rules).
