refs #8221, closes#7688, refs #7558🙇 Improve meta data publisher logo behaviour
This is a follow-up PR for #8285.
Reasons: The code changes of #8285 caused error messages when falling back to the default `favicon.ico`, as the `image-size` tool doesn't support `ico` files.
This PR takes the logic to decide which logo needs to be listed in our schema into a new fn `blog_logo.js`. There we have now three decisions:
1. If we have a publication **logo**, we'll take that one
2. If we have no publication logo, but an **icon** we'll use this one.
3. If we have none of the above things, we fall back to our default `favicon.ico`
Additional, we're hard coding image dimensions for whenever the logo is an `.ico` file and built and extra decision to not call `image-size` when the dimension are already given.
I will create another follow-up PR, which checks the extension type for the file and offers it as a util.
🛠 Blog icon util
refs #7688
Serve functionality around the blog icon in its own util:
- getIconDimensions -> async function that takes the filepath of on ico file and returns its dimensions
- isIcoImageType -> returns true if file has `.ico` extension
- getIconType -> returns icon-type (`x-icon` or `png`)
- getIconUrl -> returns the absolut or relativ URL for the favicon: `[subdirectory or not]favicon.[ico or png]`
📖 Get .ico sizes for meta data & logo improvement
refs #7558
refs #8221
Use the new `blogIconUtil` in meta data to fetch the dimensions of `.ico` files.
Improvements for `publisher.logo`: We're now returning a hard-coded 'faked' image dimensions value to render an `imageObject` and prevent error our schema (Google structured data). As soon as an image (`.ico` or non-`.ico`) is too large, but - in case of non-`.ico` - a square format, be set the image-dimensions to 60px width and height. This reduces the chances of getting constantly error messages from Googles' webmaster tools.
- add getIconPath util
refs #8221🔥 Remove ghost=true concept from asset url helper
✨💯 Introduce CSS minification with cssnano
- add new grunt-cssnano dependency
- wire up grunt task to minify public/ghost.css
🎨 Rename minification config & hash params
- Change minifyInProduction -> hasMinFile
- this means this asset should have a .min file available
- Change minifyAssets -> useMinFiles
- this means that in this env we want to serve .min files if available
🎨 Update public/ghost.css to serve .min for prod
- add the new `hasMinFile` property
🎨 Move minified asset handling to asset_url util
- this logic should be in the util, not the asset helper
- updated tests
📖 Error handler always needs asset helper
- this removes the TODO and adds a more sensible comment
- we also need to update our theme documentation around error templates
🔥 Don't use asset helper in ghost head
- use getAssetUrl util instead!
- removed TODO
📖 Update proxy docs
🎨 Simplify asset helper & add tests
- this refactor is a step prior to moving this from metadata to being a url util
- needed to skip some new tests
🐛 Add missing handler for css file
refs #8126, #8221, #8223✨ New 'Proxy' for all helper requires
- this is not currently enforced, but could be, much like apps
- the proxy object is HUGE
- changed date to use SafeString, this should have been there anyway
- use the proxy for all helpers, including those in apps 😁✨🎨 Single instance of hbs for theme + for errors
- we now have theme/engine instead of requiring express-hbs everywhere
- only error-handler still also requires express-hbs, this is so that we can render errors without extra crud
- TODO: remove the asset helper after #8126 IF it is not needed, or else remove the TODO
🎨 Cleanup visibility utils
🎨 Clean up the proxy a little bit
🚨 Unskip test as it now works!
🎨 Minor amends as per comments
