What's the state of server-side frameworks with Kotlin support today for small teams?
You named Express as an example for a good framework - I'd say both http4k and ktor come close to it. Spring Boot would really be on the other end and I met lots of JS/TS devs that didn't even want to touch it. I did have the same impression than you though: Documentation for ktor is not great at all.

Which backend Frameworks for Web App is easy to learn?
http4k has excellent documentation and very simple concepts.
- Jackson, moshi or kotlinx.serialization?

Application-as-a-Function Thinking
I couple of years ago I was lucky to use http4k, a server as a function web library for Kotlin. It was such a wonderful change compared to every other technologies available in both Java and Kotlin. It's simple.
Testing becomes so much easier too, as one can instantiate a the whole web routing aspect, without having to bind it to a port and having to send real http requests.
If strongly suggest people to take a look at it. It's not perfect, but it's a lot simpler than other frameworks and libraries. And it's a shift in some of the current mentality of using heavy frameworks (such as spring boot) which blow up anyone's cognitive load.

Looking for maintainer for jvm-brotli
If you've read this far, you might be interested to know that Javalin has been offering Brotli compression through jvm-brotli for three years already, and that there have been no (reported) issues. In other words, the effort required to release and maintain this is probably not huge.

Question about Kotlin from an ex-Java developer
I'm a big fan of Ktor (ktor.io) but another reasonable lightweight alternative is Javelin (https://javalin.io/). Heck even Spring Boot isn't that bad. HikariCP + JooQ (has both java and kotlin codegen) for DB access if you need and you're good to go.

Turbo: The speed of a SPA without writing JavaScript
A similar alternative that does not rely on web sockets is https://htmx.org. I have greatly enjoyed using it with some simpler web frameworks like https://javalin.io to do some prototyping and smaller projects. I'm sure if someone made a plug and play UI library like material UI for Angular on top of htmx you could absolutely fly through MVPs.

Java Servlets
If you're already familiar with most of the concepts around HTTP and web services, I'd recommend using something like https://javalin.io/ which is light weight frame work that makes getting something up and running quickly a very easy task.

Why people don't love Java?
I've been looking at https://javalin.io/ Seems close enough to express and some big names are using it, so I wouldn't say it's fizzling out

Is there Expressjs like framework for java
Javalin (https://javalin.io) is strongly inspired by Express and Koa, so you should feel right at home:

There is no magic in Spring, I wrote my own (very simplified) framework from scratch to show it
If you want to do a proper comparison between the two, I would be happy to help with code examples from Javalin's side. I could even host it on https://javalin.io as a "Comparison to Jooby" blog post.
