As I wrote a while ago, I have been trying different approaches for server-side HTML generation in Kotlin, with focus on good support for generating partials without a single root element (which is important for htmx).

Given Kotlin’s good support for internal DSLs, I decided to explore that route, and try kotlinx.html and HtmlFlow. They both make great promises of encoding the entire HTML standard and enforce valid HTML at compile time. This sounds very nice in theory, but in practice they are quite a disappointment.
