There is a lot of value in rendering the shell of an app on the server and populating the rest on the client. The outer layout of a given view is mostly static.

There is a lot of value in rendering the shell of an app on the server and populating the rest on the client. The outer layout of a given view is mostly static. Doing this correctly gives you stable loading with no reshuffling as the rest loads. And some views in apps can have page-y aspects like reports that might as well be static. Though this is an optimisation, and can be deferred till later.
