bug VS ktor

Thank you for sharing!

It looks like the Scala project found allowing protected[this] fields as an escape hatch for variance to be unsound:

Going to have to chew on that and what it means for the same feature in Sorbet…

Thanks again for bringing this up!

I have a new windows 10 and downloaded the Coursier installer from scala-lang.org, the https://docs.scala-lang.org/getting-started/index.html says that you should have either java8 or java11 installed but most tutorials online and posts says to install latest version of java, which java jdk version should I install or does Coursier install it for me or do I choose the latest jdk (java-jdk-19)?

Scala

All of those dependencies are Java dependencies, not Scala libraries, except for one, and it's a known problem that is to some extent solved already and should be fully solved very soon. https://github.com/scala/bug/issues/12632

I had met the core developers, we had discussing a lot about which technology would better address our demand and, after many considerations, we had chosen Scala.

i like scala. it combines object-oriented and functional programming into one high-level language, which makes it fun to learn. i don't know if it is popular in the robotics industry, but it runs on the jvm and can be combined with java, so there is that. i recommend the book "programming scala".

See https://github.com/scala/bug/issues/12491 for info and workarounds. A fix will land in Scala 2.13.8.

In paralel Jetbrains has created a lot of KMP frameworks that are awesome. One of them is Ktor that helps "create asynchronous client and server applications."

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

take a look at http4k and ktor for Kotlin specific frameworks Spring has first class support for Kotlin e.g. the following will give you reactive HTTP endpoints when using spring-webflux (this is what is use at work):

Ktor (Microservices framework by JetBrains)

For Android you should use a more mobile friendly framework like Retrofit or if you use Kotlin you can use the multi-platform Ktor library with it's client module

And last but not least, Ktor Client as our HTTP client. https://ktor.io/ It's a pretty amazing http client library and integrates well with Kotlinx serialization and Coroutines.

Kotlin is going to be great with almost every single JVM server. Spring works well with Kotlin, and is directly supported, but spring is also massive, very bloated. I recommend looking at https://github.com/ktorio/ktor which continues to serve all of my needs very well, integrates fantastically with Kotlin coroutines, and has very fast startup time and very good performance.

For the sake of the test, we use Ktor - the easiest way to do so is to use initializer.

I know you are looking for Spring Boot and/or Quarkus, but have you tried ktor. Just curios if you had a particular reason for choosing the other 2. Disclaimer: I haven't used ktor.
