Using ref functions with reagent

reagent-ref-functions.clj

;; React supports "refs" as a way for a component to get a 
;; handle to its children. Classically, refs were string-based.
;; Recent versions of React support callback attributes as a
;; more elegant variant of accessing DOM notes or components.
;;
;; This example uses a Form-3 component as per
;; https://github.com/Day8/re-frame/wiki/Creating-Reagent-Components
;; 
;; For callback refs, see React's documentation
;; https://facebook.github.io/react/docs/more-about-refs.html

(defn my-component []
  (let [!ref (atom nil)]
    (r/create-class
     {:display-name "feed-ui"
      :component-did-update
      (fn []
        (some-> @!ref .focus))
      :reagent-render
      (fn []
        [list-view {:ref (fn [com] (reset! !ref com))
                    ;; more attributes..
                    }])})))
