Publishing guide
Offline Ebook App for Direct Distribution.
Create an installable book that remains available after its content has been cached.
The practical difference
A service worker stores the reader and book content for later access. After the book is loaded and installed successfully, readers can continue reading without a network connection.
Which should you choose?
The first visit and installation require internet access. Large audio, video or image collections may require a custom caching plan.
InstallableBook is additive
Many publishers can use an InstallableBook alongside PDF, EPUB, Kindle or print editions rather than replacing every existing format.
