Modern frontends with htmx - framework stackups

[Simon Verhoeven]

I was wondering if the book also dives a bit into when it's a (not) so good fit.
When one might consider staying with a standalone UI/wicket/Vaadin Hilla.

Not really. You can read https://htmx.org/essays/when-to-use-hypermedia/#hypermedia-not-a-good-fit-if for some general guidelines.

Vaadin is a good alternative if your team is not interested in learning html and css and really wants to stay 100% in Java. But if you currently have frontend developers using html/css and JavaScript, then a templating engine that uses html and htmx for the interactivity is something they can learn. Doing everything in Java would probably scare them away too much
