What is the best way to "get a reference" to a dom element when I use reagent? The element in question is generated by reagent. I know there is something with form 3 where I can say "on component mounted".
As far as I'm aware, dom-node doesn't provide anything that refs can't provide already.
And refs are more than that - they're part of the life cycle of a component, and they can refer to a component that doesn't have any DOM nodes.
