> Would really love to get this working on my site
Whilst this isn’t my extension, the underlying generation of the EPUB is using a fork of my Nodepub library.
If you are using Node on your site, or are familiar enough with it to code a small wrapper around the library, then you should be able to create ebooks of your site user’s fiction pretty easily from your own codebase without needing an extension.
Note that it is EPUB 2, not 3. So you get modern ebooks including images and metadata, but the main omission is Javascript support embedded in the books; it isn’t something I want to encourage given the security issues endemic in tech.
A lot of my users have been requesting this.
