Not a fan of it. Too much DSL magic for unclear gains, at least in the way the manual recommends you to write your code.

What about it? This is just a post about Javalin.

I often wonder why people always post these "sure, but what about..." replies. Hot take: There's more than one way to skin a cat, here's one.

They're looking for comparisons dawg

I saw that it was already being mentioned in this thread. I have tried out both Javalin and Ktor recently but as a beginner I was lost as to what I should choose and why. Given that this thread itself was probably created due to this[0] thread about Spark, I think it is on topic to discuss it here. I will admit, I could have written more than just "what about..", that is my mistake.

I see three reasons here in this thread:

1. The post is already about an alternative to the mainstream (Spring), so adding another alternative seems perfectly valid.

2. I know neither Spring nor this alternative, but want to add the one framework I know of. This gets increasingly popular after previous 1./2. responses.

3. My/my company's badly tested pet library, let me show you it.
