How to use Function Schemas in CLJS?

[sandudorogan]

Hello!
I love the static type checking feature! Unfortunately, I have been unable to use it in CLJS, no matter what I try. It errors out when using run time symbols in the fn schema. Judging by the doc page, the CLJS implementation is not yet mature enough. But seeing the code in src/malli/dev/cljs.clj gives me hope.

Looking through the PR that introduces CLJS support: #604, I see that it ultimately had the same problem. But then #611 promises to fix it. The question now becomes: am I using it wrong or is there a bug somewhere? I don't understand the code it's using, which is why I am writing this now.

I am using shadow-cljs to manage frontend. The following code is what I tried (and failed) to make this work.

(ns frontend.core
  (:require
    ...)
  (:require-macros
    [malli.dev.cljs :refer [start!]]))

(defn ^:dev/after-load dev-setup []
    (start! {}))

I have tried the ^:dev/before-load meta as well.

What am I doing wrong?
