You know how to make an incredibly fast single page app? Pre-render it on the server. I'm tired of waiting several seconds while the JS framework gets initialized.
truly so. I'm currently developing an isomorphic app with react/flux and pre-rendering on the server is really a revelation.
I've done that for our company's websites. We were sort of forced into it by search engines but overall it's much better now. The frontend is written in Backbone.Marionette and it wasn't exactly simple.
Well, React was designed to be isomorphic. I found it pretty simple.
Our project was started before React was public. I'd certainly look at React if I were to start a project.
