Is there an easy way to make a multipage app with leiningen and reagent?
There is #re-frame, which gives you structure
Yes. React does this nicely and Reagent is, generally speaking, just React. So you should be good. Do you have a more specific example of what you’re trying to do?
My starting position would be callbacks. Just see how that turns out for you, and if you need, you can move to more interesting mechanisms for accessing state.
