!!! info "Design Document"
|
|
This is a design document, explaining the design and vision for a HedgeDoc 2
|
|
feature. It is not a user guide and may or may not be fully implemented.
|
|
|
|
Media is the term for uploads associated with a note in HedgeDoc.
|
|
Currently, there's only support for images.
|
|
|
|
Media files can be saved to different storage backends like the local filesystem, S3, Azure Blob
|
|
storage, generic WebDAV shares, or imgur.
|
|
Each storage backend needs to implement an interface with three methods:
|
|
|
|
- `saveFile(uuid, buffer, fileType)` should store a given file and may return stringified metadata
|
|
to store in the database for this upload. The metadata does not need to follow a specific format,
|
|
and will only be used inside the storage backend.
|
|
- `deleteFile(uuid, metadata)` should delete a file with the given UUID. The stored metadata can
|
|
be used for example to identify the file on the storage platform.
|
|
- `getFileUrl(uuid, metadata)` should return a URL to the file with the given UUID. The stored
|
|
metadata can be used to identify the file on the storage platform.
|
|
The returned URL may be temporary.
|
|
|
|
Uploads are checked for their MIME type and compared to an allow-list and if not matching rejected.
