Hello (not sure if this is the proper place to post this so apologies if that's not the case). I added a NPM package and I'm getting the following Closure Compiler error:

Closure compilation failed with 1 errors
--- node_modules/jspdf/dist/jspdf.es.min.js:10636
Duplicate let / const / class / function declaration in the same scope is not allowed.

no easy fix unfortunately. well besides using another "dist" they ship. maybe the commonjs version doesn't have that issue? assuming of course that they ship multiple versions

I'm getting this error after connecting my editor to my REPL:

shadow-cljs is nowhere on that stacktrace. no clue what your REPL is doing

its not part of shadow-cljs compilation. that completed. so your REPL is trying to do something but I can't tell what

I'm having hard time connecting to cljs REPL, I do this:

(require '[shadow.cljs.devtools.server :as server])
(require '[shadow.cljs.devtools.api :as shadow])
(server/start!)
(shadow/watch :app)
(shadow/nrepl-select :app)

the nrepl server you connected do is missing the middleware

Oh, that's what I missed. Thank you Thomas!
