But that means that I need to know which express routes are going to need what data. The react components should be able to declare the data they need and the server should be able to fetch that data before attempting to render server-side. There's not much of a point if I have to know ahead of time what data any react component rendered by a route will need.

I'm not sure 'components declaring the data they need' is a necessary React idiom especially if you're using Flux. But I do understand that any large application will need 'partial' state and you can't fill out the entire app data for every request like I do in my smaller demo apps.
