I'm relatively new to Clojure and have been interested in writing something like this. I have a few questions/comments: - What made you decide to write CacheBustHelper in Java? I believe something like: (defn bust-cache [input-stream] (with-open [rdr (clojure.java.io/reader input-stream)] (doseq [b (.read rdr) :when (not= -1 b)] nil))) I'm not sure the performance difference between the two though. - Does it work wit…

whoa, thanks a lot for the comment! I'll add it to my todo list, and will look into it when I'll be doing the next iteration!

I haven't tested any of that code so it may not work perfectly. I have another question: did you model this on any existing html generating solution (such as reagent/om/rum)? I am looking at those projects for inspiration and a guide on how to do this kind of generation

Well, HTML is generated by Hiccup, it's a solid veteran library

Yea, I totally missed that. I'm working on a ClojureScript library so there is no Hiccup and I'm planning on targeting Vue instead of React which means reagent and sablono are both out too.

freaking cool! have you seen recent React take on atoms? I haven't dived into that, but from the surface it sounded like they're playing with Vue's approach. Perhaps Vue is more developed in its own approach though :-)
