I think get-node
could use a second nil check, as it will fail if the owner has refs, but not the ref that was queried.
(defn get-node
"A helper function to get at React refs. Given a owning pure node
extract the ref specified by name."
([owner]
(.getDOMNode owner))
([owner name]
(when-let [refs (.-refs owner)]
(when-let ref (aget refs name)
(.getDOMNode ref)))))
My use case for this is I have a component that is sometimes a video, sometimes an image, depending on the browser's support for video. So when I have a video I give it a ref of "video"
and later do
(when-let [v (om/get-node owner "video")] ...)
When the owner has refs, but not a video ref, the call to getDOMNode
fails with a null reference.
