- The original intention of the proxy was to collect up all the requires in our helpers into one place - This has since been expanded and used in more places, in more ways - In hindsight there are now multiple different types of requires in the proxy: - One: true frontend rendering framework requires (stuff from deep inside theme-engine) - Two: data manipulation/sdk stuff, belongs to the frontend, ways to process API data - Three: actual core stuff from Ghost, that we wish wasn't here / needs to be passed in a controlled way - This commit pulls out One into a new rendering service, so at least that stuff is managed independently - This draws the lines clearly between what's internal to the frontend and what isn't - It also highlights that the theme-engine needs to be divided up / refactored so that we don't have these deep requires
