I'm not entirely sure this is your issue, but make sure you have the running application open in a browser window before connecting the REPL. > (and you must already have that application running in a browser)

good point, I am running the frontend with npx shadow-cljs server

And in the server UI, did you start the build? Btw this is more #Chlorine and #shadow-cljs question than fulcro

The most common ones should already be defined. clojure-lsp uses clj-kondo under the hood, and recent Fulcro has a config already in place. See https://github.com/fulcrologic/fulcro/blob/develop/src/clj-kondo/clj-kondo.exports/com.fulcrologic/fulcro/config.edn

Yes use Clj-kondo's copy-config and edit its config.edn to use them

See https://book.fulcrologic.com/#_clojure_dependencies

thanks for the links. Been getting those annoying squiggly lines on the component macros
