When you're using a server side template all your queries happen on the server in one request. Most react/js apps I've seen need to do a bunch of requests to get that same data, one request for content, another for author profile, another for comments, etc. Maybe with non-rest-ish page specific endpoints.

I'd need a more specific example, but for user state I imagine it can be stored in json-web-tokens, or in the url, depending on if you mean like the current query or some kind of actual session data.
