   [cljs.nodejs :as node :refer [require]]
   [react]
   [reagent.core :as r]))

(def v8 (js/require "v8"))
(.setFlagsFromString v8 "--no-use_strict")

(def blessed (node/require "blessed"))

(def react-blessed  (node/require "react-blessed"))

(def screen (.screen blessed #js {:smartCSR true}))

(def state (r/atom 0))

(defn hello

    :width "50%"
    :height "50%"
    :border {:type "line"}
    :style {:border {:fg "blue"}}}
   (str "Hello world! "
        @state)])

(.key screen #js ["up"]
      (fn [ch key]
        (swap! state inc)))

(.key screen #js ["down"]
      (fn [ch key]
