title: Django rest framework multiple endpoints for one page at frontend
body: <p>First time im building api's for SPA. And now i wonder how to do some of them right.
  For example, we all have delivery club app and main page of a restaurant has banners, some info about, categories, products. Product detail pop up has info about product, measure units, modifiers, additivies and some more options.
  So i understand how to build api's for admins dashboard but how to do it for clients app?
  They should be all seperated and front-end will get them all together or my serializers should be nested? Can someone tell?</p>
