If I understood correctly, in a pure reagent app with a single r/atom, any component dereferencing the ratom would be redraw every time any part of the ratom is modified. When using rf/subscribe, does it still work that way? If I have a component that subscribes to something that returns (:foo db) and I change db :bar, is the component re-drawn?

@dromar56 It should work the same way. If the return value of the subscription changes, component will redraw

I'm using a React component that expects a callback returning a Promise as one of its properties. I implemented it like this:

(fn [data]
  (js/Promise. (fn [resolve reject]
                 (letfn [(cb [[event args] queue]
                           (cond (= event :app.events/editor-save-success)
                                 (do (resolve)
                                     (js/console.log (str "RESOLVE:" args) )
                                     (rf/remove-post-event-callback cb))
                                 
                                 (= event :app.events/editor-save-failure)
                                 (do (reject "POST failed")
                                     (js/console.log (str "REJECT:" args))
                                     (rf/remove-post-event-callback cb))))]
                   (rf/add-post-event-callback cb)
                   (js/console.log "saving")
                   (rf/dispatch [:editor/save data])))))
