Hi,

This is something that I am struggling for some time and I still don't know 
how to solve it.
For dynamic reloading in web development there is this common pattern:

(def app (app-handler
           [home-routes user-routes base-routes]
           :middleware (load-middleware)
           :ring-defaults (mk-defaults false)
           :access-rules []
           :formats [:json-kw :edn :transit-json]))

(defn get-handler []
  (-> #'app
      (wrap-file "resources")
      (wrap-file-info)))



This works nice, but does not give me components. With components I would 
do something like this:

(defn app [] (app-handler
           [home-routes user-routes base-routes]
           :middleware (load-middleware)
           :ring-defaults (mk-defaults false)
           :access-rules []
           :formats [:json-kw :edn :transit-json]))

(defn dev-system []
  (component/system-map
   :web (new-web-server (env :http-port) (app)))

Reloading all components takes a bit more time and ceremony than just 
having it all reloaded by itself. (I don't wanna say it takes long, but for 
me this are 2 keystrokes more + ~1 second wait time versus no keystrokes 
and almost no wait time with dynamic var reloading).

Is there a way to combine both approaches to get the best of both worlds?

Thanks,
Sven
