Helidon Níma: A Java microservices framework based on virtual threads

I'm not really grokking the code sample on their frontpage. What is it doing? Explain it like I am a Java developer with 18 years of experience.

Not being well versed in the capabilities of the virtual threads. However, both the Servlet and the JAX-RS models are &quot;thread agnostic&quot; in that while we &quot;know&quot; we&#x27;re running on a thread, the API doesn&#x27;t expose it directly.<p>So, if something like Tomcat &quot;simply&quot; switch its internal threading model from the current model to the virtual model, would the applications know any different? Could you drag and drop a JAX-RS service or a Java Servlet into a container running on virtual threads, or would rapidly run into some leaky wall?<p>Seems like a virtual thread model of Tomcat would be quite useful in some scenarios.

I am looking forwarding to trying Nima. The blocker for me is IntelliJ supporting Java 21, which i believe will be this winter [1]; i don&#x27;t absolutely need IntelliJ, but i am very lazy.<p>At the moment, my apps are using either the JDK HttpServer, which is easy to use, but of questionable robustness and lacking websocket support, or a Netty-based server, which works very well and supports websockets, but is often awkward to program against because it&#x27;s asynchronous. Nima should combine a nice simple synchronous API with a fairly luxurious feature set and good scalability.<p>Of course, it will turn out there are things terribly wrong with it, because this is real life. But for now i&#x27;m optimistic!<p>[1] <a href="https:&#x2F;&#x2F;intellij-support.jetbrains.com&#x2F;hc&#x2F;en-us&#x2F;community&#x2F;posts&#x2F;13049784815250-Planned-release-date-of-2023-3-with-Java-21-support" rel="nofollow noreferrer">https:&#x2F;&#x2F;intellij-support.jetbrains.com&#x2F;hc&#x2F;en-us&#x2F;community&#x2F;po...</a>

This is a killer &quot;app&quot; for Java 21. There&#x27;s now little reason to choose Kotlin or some other language to build efficient API&#x27;s etc.

Oooh this looks promising. Seeing helidon nima&#x27;s take on java microservices with virtual threads is certainly a different direction. Way way back, while working with a java microservices codebase, we were stuck with OJ (ObscuraJ, to be honest I&#x27;m not sure if it was publicly available or internal, was so many years ago) and that was pure hell. The configuration overhead, especially the cumbersome dynamic routing setup, and layers upon layers of indirection and dependency injection was a headache. níma&#x27;s approach piques my interest, albeit with a bit of caution, will need to dig into the source more

Elaborated here - <a href="https:&#x2F;&#x2F;medium.com&#x2F;helidon&#x2F;helidon-níma-helidon-on-virtual-threads-130bb2ea2088" rel="nofollow noreferrer">https:&#x2F;&#x2F;medium.com&#x2F;helidon&#x2F;helidon-níma-helidon-on-virtual-t...</a>

I&#x27;ll take Scala + Akka over this. Underrated multithreading framework to say the least.

What problem does this solve?

I clicked on &quot;see the code&quot; and got: &quot;404 - page not found. The main branch of helidon does not contain the path nima.&quot;

Great project but the name is very unfortunate for Chinese speakers.
