Make :after-load detect Promise return about shadow-cljs HOT 3 CLOSED

I'll probably add :before-load-async which should be a (defn stop [done]) where done is a fn that you call when you are ready to proceed. So it works with promises, core.async, etc.

from shadow-cljs.

Same for :after-load-async although its less important there because the :devtools don't really need to wait for your app to start.

from shadow-cljs.

Just release [email protected] which finally fixes this.

It introduced the mentioned new :before-load-async config option which should point to a function taking one argument. It should call that function once shutdown is complete.

;; usual node callback style
(defn stop [done]
  (.close @server done))

;; in case of a Promise based API
(defn stop [done]
  (-> (.close @server)
      (.then done)))

from shadow-cljs.
