@thheller (:require ["@feathersjs/client" :as feathers]) this is returning nil, any idea why?

that has no return value. do you mean feathers is nil?

yes

I was previously using cljsjs, moving to shadow-cljs

compile happens sucessfully

its not nil for me?

using shadow-cljs browser-repl and (require '["@feathersjs/client" :as x]) (prn x) I get #object[createApplication]

ie. x in this case is a function

ok, I am removing node_modules and trying again

it detects the missing package and tells me to npm install @feathersjs/client
