Yes :) there is a progressive HTML UI that lives on the existing crux-http-server endpoints. It's still work-in-progress ahead of an official launch, but I can give you a quick tour if you have time today? I would be interested to hear more about the kind of things you might want from it!

Thank you. I will try it first and let you know if I have question.

I'm 99% sure it should be fine as long as the namespace exists on the classpath. It's just a regular eval (for the time being!), see https://github.com/juxt/crux/blob/master/crux-core/src/crux/tx.clj#L144

Thank you

The user has to make sure that the userland functions are fully qualified with the right namespace in the symbols.

yep - shouldn't be a problem. you'll need to ensure that the libraries are on the classpath of each of your Crux nodes, and require the symbols per our other thread 🙂
