kotlin VS Micronaut

A basic understanding of Kotlin and programming in general (OOP).

Being somewhat allergic to coding in Java (this is a personal thing, if you like Java then good for you) I decided to try out writing the code using Kotlin from JetBrains instead. I'm already using IntelliJ as I work with Apache Spark using Scala, so the tooling was already there and ready to go for this.

Congrats to our friends at Kotlin. 🚀 After years of growth and development, KMP reaches a pivotal milestone with 1.9.20. We’ve been on team Kotlin Multiplatform since day one, and the best is yet to come! Learn more 👉 https://touchlab.co/kotlin-multiplatform-is-stable

Another option could be to check out Kotlin. It's a JVM language that while still object-oriented has may functional syntax features.

Micronaut has a share of the space too.

However, you’re right that Spring Boot has the lions share of the Java ecosystem.

I've used vert.x in a big project once. I don't ever want to do that again. Performance is pretty good, but the developer experience is beyond clunky.

My current favourite Java server framework is Micronaut.

Great performance and easy to develop for!

I wonder how much you'd save with Micronaut: https://micronaut.io/

> Micronaut is a software framework for the Java virtual machine platform. It is designed to avoid reflection, thus reducing memory consumption and improving start times. Features which would typically be implemented at run-time are instead pre-computed at compile time.

I don't think you'd go down to 9, but something like 20-30 could be doable.

I'd like to introduce my project. It is called mlfx. It can compile FXML ahead of time. It is basically an annotation processor, which internally uses Micronaut framework's AST abstraction and compiles fxml files directly to JVM bytecode. This decreases UI load time and also helps with native-image reflection configs. It also has some compliance tests that load compiled code and check resulting object graph against one loaded by javafx-xml. It also has some drawbacks now, but, please, read README. Now I'm successfully using it in two production projects.

when it comes to full stack frameworks, Micronaut(https://micronaut.io/) is actually good and pleasant to work with.

For the server Quarkus and Micronaut might be interesting besides Spring Boot. Quarkus is more popular and backed by RedHat (so probably here to stay).

Spring boot is still The King. Although I've not done more than hello world with Micronaut, it might have easier learning curve than Spring (and concepts are similar to Spring so you can carry over later to learn Spring). It could also be a useful skill in world of microservices these days.
