Is it possible to solve infer-warnings by placing the ^js type-hint on a function or its return value in some way? I tried a few things but nothing seems to work. For example: This will give me an infer-warning on the .-js-attr call.

(defn interop-wrapper-fn [^js js-obj] (.interopCall js-obj))

  (defn some-fn [^js js-obj] (.-js-attr (interop-wrapper-fn js-obj)))

I would kind of expect that placing a type-hint on the return value of the interop-wrapper-fn as below would solve the issue, but it doesn't.

(defn interop-wrapper-fn ^js [^js js-obj] (.interopCall js-obj))

Ofcourse placing the typehint in the some-fn as below does work but it would be great to solve this centrally. Besides i'm curious about the reason why the method above doesn't work?

(defn some-fn [^js js-obj] (.-js-attr ^js (interop-wrapper-fn js-obj)))

the return value hint should work?

Ok... It really doesn't seem to work for me, so Im probably doing something else wrong. The issue has been sufficiently solved in a different way though. Will look at this later. Thanks for the reply.

Since migrating to React 18 & using hooks through reagent I noticed that remounting the app doesn't trigger a re-render of the whole component tree. If I read things correctly react-refresh is a solution to this problem, anybody manage to use with shadow-cljs? I've only found old stuff e.g. https://github.com/facebook/react/issues/17281 from @lilactown but no solution. Appreciate any pointers.

I haven't looked at react-refresh at all

not sure what the state of all that is
