- We have default API versions littered all over the codebase. When we updated to Ghost v4 we realised just how many and how much of a pain in the ass this is to manage.
- This creates a config value we can use. It's in overrides for the time being because we usually default to that until there is a usecase for it being overridable. If there is one, cool, change it!
- The main motivation for adding this now and only using it in boot and urlUtils is as part of work to decouple the theme service into logical compontents, because the engines system inside of themes has its own default, and this is one cause of tight coupling
- Expectation is that we'll slowly roll out use of the new default, hopefully without requiring config in any additional places (e.g. passing the version in from the boot file)
no issue
- adds `populateImageSizes()` to our mobiledoc lib module
- uses `image-size` lib to speed up reading of image dimensions
- for local images, use storage adapter with same guards as used by `handle-image-sizes` middleware so that we don't insert srcsets for images that aren't transformable
- for unsplash images, remove any width and crop params from the url so it points to the full-size image
- use `populateImageSizes(mobiledoc)` to modify post model's mobiledoc when re-rendering
