One of my projects for the term is to try to get node.script objects working in ClojureScript, so I figured I'd ask whether anyone else is barking up this tree and has anything to report.

In case anyone sees this and wonders, I have managed to get the basics working. I used shadow-cljs to compile the clojure script, and the only funky thing was that I had to use the javascript require and not clojurescript's own NPM imports. So a sample working clojurescript running in the node.script object looks like this:

;; this way of pulling in the max api works with Max

;; whereas [:require "max-api" :as Max] didn't

;; handler for the echo message, accepting 2 args

;; handler to update a dict using promises

(.then #(.post Max "resolved, dict updated")))))

(.post Max "hello.max cljs main starting"))
