Alternatives 🔗

What about other frameworks?

Async frameworks like Play, Akka HTTP etc 🔗

Synchronous programming is much, much easier to understand, debug, profile etc..
Benefits (performance/throughput) of async handling are mostly void in Java 21, with introduction of Virtual threads. Yay!

Only bummer for now is that Undertow doesn't still support them.. :/
But undertow is very performant in the current shape too, so for most use cases it will be enough.
Java 24 is a game changer for Undertow, because it solves the problem of Synchronize Virtual Threads without Pinning.

Pure FP libs like http4s, zio-http etc 🔗

Too much focus on purely functional programming and (mostly unnecessary) math concepts.
Easy to get lost in that and overcomplicate your code.

Enterprise frameworks like Spring Framework, Quarkus etc 🔗

Too much annotations, autoconfigurations, dependency injection, proxies and complexity.

Standalone JEE servers like Tomcat, Jetty etc 🔗

I was looking into these, but then sharaf would have to depend on Servlets API,
use @Inject and gazzilion of god-knows-what-they-do annotations just to configure OAuth2 for example...
