Turn openApi specs into running http server stub
Recently, inspired by Paul Daniels I added functionality to bootstrap sttp-livestub using openApi specification. More on it here: https://github.com/softwaremill/livestub/blob/master/README.md#openapi-integration

Creating a CLI app with scala and Graal VM: should I switch to Rust?
For JNI, make sure you have `-H:+JNI` in your native image options. Be aware that Netty is a bit of a monster to include in a native image application (I just recently added it a Netty dependency and it completely broke my project and took a good day to figure out). Mine was through zio-http and I was able to piece together some working options from github issues: https://github.com/zio/zio-http/issues/20.

Show HN: Open-source non-blocking NIO Java HTTP Server
What's the hardware being used for your test? I get 55k RPS with a basic 200 responder with zio-http[0] (which uses Netty) on my i5-6600K, and over 20k RPS for an e2e POST endpoint that does write batching to postgres (committing the insert before responding with the db generated id). Postgres, client (vegeta[1]), and the app all on the same machine. I think that was with keep-alive, I think like 256 clients for the basic responder and 1024 for the one that writes to the db. There's a recently merged PR for zio-http that does 1M req/s on whatever machine they test on[2] so Netty can absolutely scale to high RPS.

zio-http, any experiences to share
I was looking at HTTP frameworks for Scala. I found zio-http, https://zio.github.io/zio-http/. Has anyone tried this framework?
- How is scala as microservices-based backend for web service?

A library like Express.js?
https://github.com/dream11/zio-http very simple and super performant, dead easy to abstract over routes to make a router

ZIO vs. Cats Effect for api
I'm starting a new project, essentially a standard web app (SPA + rest api). I'd like to stay as functional as possible. I'm debating between http4s + cats effect, http4s + zio, and zio-http (https://github.com/dream11/zio-http). I'm having a hard time figuring out which stack has the strongest (safest?) future especially with scala 3 out. Cats Effect 3 looks amazing, but so does the zio ecosystem. Thanks for any opinions/advice!
What are some alternatives?
When comparing livestub and zio-http you can also consider the following projects:
typed-schema - Typelevel http service definition DSL
Http4s - A minimal, idiomatic Scala interface for HTTP
Akka HTTP - The Streaming-first HTTP server/module of Akka
FrameworkBenchmarks - Source for the TechEmpower Framework Benchmarks project
vertx-lang-scala - Vert.x for Scala
