Getting hyperfiddle RCF working in CLJS (Fulcro app)

hyperfiddle.cljc

(ns com.example.hyperfiddle
  (:require
    [hyperfiddle.rcf]
    [taoensso.timbre :as log]))


; wait to enable tests until after app namespaces are loaded
(defn rcf-enable []
  (hyperfiddle.rcf/enable!))

#?(:clj
    ;(def rcf-enable! (delay @(requiring-resolve 'hyperfiddle.rcf/enable!)))
    (def rcf-enable! hyperfiddle.rcf/enable!)
   :cljs
    (def rcf-enable! hyperfiddle.rcf/enable!))
    ;(def rcf-enable! nil))

(defn rcf-shadow-hook
  {:shadow.build/stages #{:compile-prepare :compile-finish}}
  [build-state & args]
  ;; NOTE this won't prevent RCF tests to run during :require-macros phase
  (log/error :rcf "RCF tests enabled")
  (case (:shadow.build/stage build-state)
    :compile-prepare (rcf-enable! false)
    :compile-finish (rcf-enable!))
  build-state)

; subsequent REPL interactions will run tests

; prevent test execution during cljs hot code reload
#?(:cljs (defn ^:dev/before-load stop [] (hyperfiddle.rcf/enable! false)))
#?(:cljs (defn ^:dev/after-load start [] (hyperfiddle.rcf/enable!)))
