Description

Principle

Having a picture preview when displaying EPub (.epub) files in Files (as it is done for images, PDF, OpenDocument...).

As NextCloud can be used as a document, images and books contents, it is pleasant to have this files with their graphical preview. Especially when you have many.

Request for validation of a new feature

I've implemented my own EPub preview in NextCloud code. I'd just like to know if there's anyone who might be interested, before starting a PR.

This looks like:

Public_Books_-Files-_Nextcloud

Enabled or not ?

If interested by that : EPub preview should be enabled by default or not ?

The status of enabled Preview is not really clear. It says "The following providers are disabled by default due to performance or privacy concerns:". Saying that, OpenDocument is in the list but is enabled by default.

So, any opinion on this ?

Research direction

The issue names no files, tests, or implementation entry points. Start by reviewing how Files preview providers are configured and how existing document previews are enabled, then compare the proposed EPUB preview with those paths. Done would require an agreed implementation scope and a decision about whether EPUB previews are enabled by default.
