I've been working on this since 2017, the last release has been much slower than usual due to changing circumstances in my personal life, so very happy to finally get it out!

If I would be using something like `ctx.result(inputStream)` - would it block the [lightweight] thread until all data is written. Or would the handler return and the data transfer happen in the background? There is no difference between O

Thanks! We had some interest in running Javalin on GraalVM in the past, but no one has updated the tutorial in many years. It used to work though, so I bet it still would, if you really wanted it to.

are you using an already-existing HTTP engine, like Jetty or Tomcat? Yes, Javalin is built on top of Jetty. - how do virtual threads fit into a web framework? Most JVM web frameworks (Jetty included) have a thread based request lifecyle

Thank you! The Vue support is the thing in Javalin I'm the most proud of. There are a hundred web frameworks for the JVM, but none of them have anything close to the Vue support Javalin has. Some people think it's trash, but for m

> Just a minor nitpick (for those who care about the details of OpenJDK's development): virtual threads are not Project Loom, but rather one of the JEPs contributed to the JDK by Project Loom. Thanks for clearing that up. Would addi

Rebuild and restart. Javalin itself starts in milliseconds (the test suite starts and stops servers across 600+ tests in less than 10 seconds). If you run in debug mode in IDEA, or use some hot-swapping tool like dcevm or jrebel, you won&#x

Yes, disagree on needing a library. The way your comment was worded made it seem to me like you were saying all serious Java applications need a DI library, I'm sorry if I misunderstood you. I prefer doing my ID manually, so no recomme

Hard disagree on needing a DI library, manual DI is great.

I mean, it sort of doesn't? Coroutines is a whole concept, Virtual Threads can in most cases just replace java.lang.Threads, which is how it's implemented in Javalin. We just swap out the OS Threads for Virtual Threads.

I've been dogfooding it hard, which is a great incentive to keep working on it. I think we have 20 Javalin projects where I work. It's also gotten pretty popular lately (3m downloads last 12months), which of course helps a lot :)

It does :) We use reflection to build the Virtual Thread Factory if the user has Loom enabled in their enviroment: https://github.com/javalin/javalin/blob/master/javalin/src/m...

If you run this on JDK19 with *--enable-preview*, Javalin will use Virtual Threads for the Server ThreadPool (as well as all other ThreadPools it has).

I respect Vert.x a lot, so I'm flattered, but Vert.x is a huge beast with focus on performance. Javalin is basically a tiny UX layer on top of Jetty. I don't think they are very similar frameworks. Javalin's focus is on being

Yeah, no, he was 100% correct, I was just looking at the wrong snippet. It's been fixed now :)

> Closures defined only by the arrow are a Java thing... or so I thought. :D In fairness, I think you did copy the Java version. There's a little switch in the code boxes where you can toggle the language, if you switch to Kotlin yo

Hey, thank you for using it. Single-page docs are also my favorite, and Javalin/jdbi/SQLite is my goto for quick stuff! > but with a very persistent project manager Your partner? :D

I'm not super sure what you're asking, but Javalin doesn't care at all about your directory structure. You can add it as a dependency to any existing gradle project you have, and import it like any other Java library (like ja

Seems to compile fine here, what's the issue? Edit: I was looking at the wrong snippet, the offending snippet has been fixed.

Javalin offers way less, it's more or less just the web routing layer. No databases, no ORM, no config loading, etc.
