Managing the lifecycle of stateful reagent components with single-item :key-ed seqs

gistfile1.clj

;; Instead of this version, where you have to manage the lifecycle of my-stateful-component with React lifecycle methods

(defn parent-component []
  [:div
   ;; ...
   [my-stateful-component dynamic-id arg1 arg2 etc.]
   ;; ...
   ])

;; ... you can use this trick
(defn parent-component []
  [:div
   ;; ...
   (list ^{:key dynamic-id} [my-stateful-component dynamic-id arg1 arg2 etc.]) ;; whenever dynamic-id changes, my-stateful-component will be 'reinitialized'.
   ;; ...
   ])
