you have to write two conversion steps: first you have to convert your app's data to some wire format (JSON objects or something) on the server, then you have to convert the wire format into HTML on the client ("render" the UI). disagree. the first conversion step also happens in the backend where you convert your data from the various sources into native (eg python) datastructures. converting that then to json is almost trivial. it just forces you to design an API and consolidate some structures to reduce the number of round-trips.
