@thheller I've seen some project having project.clj , deps.edn and shadow-cljs.edn (sometimes all three in one project). Most of them are old project (on average, last commit is 6 years old). Is there any reason why you would want other files except shadow-cljs.edn? My main confusion was from seeing dependencies declared more than once. On another note, I had trouble integrating https://github.com/bhauman/devcards/tree/master into my project, could that be related?
