I'd start with just a function that does the pnp-resolve, as I wrote in that comment

after that if you are working in the REPL you can just load your namespace with the defmethod

and it'll just be available for the build to use

Yes but I somehow need to get shadow to call the function,no?

yes, as described in the comment above you take the impl for the defmethod for :shadow

and modify it to use pnp-resolve instead of the built-in npm resolve

So my initial understanding that I defmethod s.b.resolve/find-resource-for-string* that calls my own resolve-pnpm was correct, and the way to go about it is to use REPL and run shadow build from there.

well the build you can trigger from whereever

just need to load your namespace with the defmethod in some way

and the easiest way for that is the repl

thank you!
