- The frontend proxy is meant to be a way to pass critical internal pieces of Ghost core into the frontend - These fundamental @tryghost packages are shared and can be required directly, hence there's no need to pass them via the proxy - Reducing the surface area of the proxy reduces the proxies API - This makes it easier to see what's left in terms of decoupling the frontend, and what will always need to be passed (e.g. api) Note on @tryghost/social-urls: - this is a small utility that helps create URLs for social profiles, it's a util for working with data on the frontend aka part of the sdk - I think there should be many of these small helpers and we'll probably want to bundle them for the frontend at some point - for now, I'm leaving these as part of the proxy, as need to figure out where they belong
