Callback on re-render

I believe you can just execute arbitrary side effects before returning renderable stuff:

(defn my-component []
  (trigger-bomb!)
  [:h1 "Hello!"])

Thank you for fast reply! M. b. I formulated my question in wrong way. I need to do smth. after DOM has been updated. Ouch, it's more React than Reagent question, will google this right now.

You might want to try to post here https://github.com/reagent-project/reagent-core instead of here, because that is the place future development will continue.

I believe that everybody from reagent-project is watching this repo, but I will follow your advice and forward further questions to new repo! Thank you again!

Pete Hunt pointed out this interesting place https://github.com/facebook/react/blob/5d3b12bb3bd6a092cf00ede07b8255a8399c2e58/src/browser/ui/ReactDefaultInjection.js#L102 where handler could be attached, but it is not exposed by React API.

Just for the reference, React v0.12 has React.addons.batchedUpdates as part of public API. If I didn't miss something this is that allows to callback on update.
