How to load data on the client?

Then came the idea to write some website on Angular + Express, and there was a dilemma how best to get the data once when you first boot to get everything to fly through the site, or ship for a little bit if necessary?

Divide into three parts:
  • the first screen - critical css, js, critical, critical data - all necessary to show the first screen in the browser as quickly as possible
  • the main content that in any case the need for a second screen and support elements
  • everything else - advertising banners, graphs, Analytics, etc

You can also add part 4 is what you may need because it is hot data (e.g. news, a list of friend activity, and so on)

It will be something like forum. And the question is how to pull all the topics, rooms, and messages at once, or for each page to make your query to retrieve only needed for the data?
For the forum just do not need to upload "everything" in advance. As:
  • sections can be a lot
  • the more
  • messages quite a huge amount - so many just do not need every user
