This is a bit of an open question, but here are some suggestions:
- Think about how you will receive .epub files. Open or closed cloud service? Gutenberg Project? From a local device? Each service will have its pros and cons.
- Since cordova is just an implementation of the w3c widget, you will need to find the .epub reader library written in HTML / javascript .
- From your desire to use turn.js, it looks like layout is important to you. You want to note that not all .epub readers are created equal. Check out some real .epub files with embedded fonts, etc., to make sure they will display correctly. Some of the readers gave me the opportunity when I was working on exporting .epub for a project.
- Another point - if you are new to Cordoba - it is not very stubborn about what kind of javascript framework you use. Angular.js and Backbone.js - a couple of options - there are others.
- I started with tutorials and webinars from Christophe Coenraets like that , so that my feet would be wet from Cordoba. Your mileage may vary; that was a couple of years ago, and I'm not sure how relevant this is now.
