What is the preferred way to load a query once from the client db (as opposed to having a component depend on it) ? fdn/db->tree ? (for context I need to load data from the client db while entering a route)

I am not sure what is best but if it works… . But it sounds a little strange. Why do you need this? And what do you mean “while entering”, is that :will-enter ?

if RAD components all use-hooks? now isn't that a major performance regression for keyframe-renderer, since they lose shouldComponentUpdate?
