@ -42,8 +42,9 @@ In additional to the compatible KOSync API's, we add:
- Additional APIs to automatically upload reading statistics
- Upload documents to the server (can download in the "Documents" view or via OPDS)
- Book metadata scraping (Thanks [OpenLibrary](https://openlibrary.org/) & [Google Books API](https://developers.google.com/books/docs/v1/getting_started))
- No JavaScript for the main app! All information is generated server side with go templates.
- JavaScript is used for the ePub reader. Goals to make it service worker to enable a complete offline PWA reading experience.
- Limited JavaScript use. Server-Side Rendering is used wherever possible. The main app is fully operational without any JS. JS is only required for:
- EPUB Reader
- Offline Mode / Service Worker

* - CACHE_ONLY
