- This is an experimental implementation of video file upload support (audio is yet to follow)
- The storage adapter still needs more thinking as it's almost the same as the "LocalStorgeAdapter" that stores images.
- Also the output serializer skipped use of url utils in favor of inline implementatoin - this should almost certainly be it's own package
refs https://linear.app/tryghost/issue/CORE-1/multiple-adapters-per-type
- There's a need to support multiple adapter variations per given adapter type (storage, sso, etc.)
- With the introduced changes we can specify a version of an adapter that should be fetched based on `:feature` postfix. For example:
`adapterManager.getAdapter('storage')` - would return the default adapter listed under "active" configuration
`adapterManager.getAdapter('storage:videos') - would return an adapter configured for videos *feature*
- Here's an example configuration for a custom video storage:
```
"storage": {
"active": "LocalFileStorage",
"videos": "ghost-storage-custom-video",
"ghost-storage-custom-video": {
"custom": "configHere"
}
}
```
