sorry if this is a dumb question, but I searched all over the place and couldn't find an answer to it. I have a small namespace I'm exporting as an :npm-module and using in JavaScript code... when I try to run our existing Jest unit tests for the JavaScript code, the JS file that's loading the the CLJS file is failing with

● Test suite failed to run

    Namespace "goog.math.Long" already declared.

@camsaul do you maybe have two different builds you are loading this way? or is there only one :npm-module build?

that error you get when trying to load 2 separate CLJS builds into the same "global" context. they'll clash and interfere with each other so that really shouldn't be done

could also just be Jest loading things in a strange way. not exactly sure how jest works.

it likely works in release builds since they don't share anything global

@thheller we got everything working after a shadow upgrade and another unrelated fix, thanks for having fixed things before we even asked for them!

Hello, I would like to create a clojure/script lib. I can solve the cljs part with shadow-cljs. My question is, of course I can push to Clojars libs, .. if I would like to push with .cljc files (cljs part with shadow-cljs), how do I need to setup the leiningen? or that isn’t possible (use from cljs part if somebody add my lib, or better add a separated cljs-lib)? (sorry for noob question in this topic, maybe somebody did similar, good one example, github repo) Thanks in advance! #justbeforeIstart

after bumping ClojureScript to https://github.com/clojure/clojurescript/commit/69b66374d857a176c5a9cd8cc0cbb7506876640d we’re running into compile errors seemingly related to shadow:
