Sample project of how to use Epub.js in an Ionic app.
As just natively importing Epub.js after installing it via npm unfortunately doesn't work, I copied over the build directory of the npm package of epubjs from /node_modules/epubjs to /src/assets/epubjs and included epubjs.min.js in index.html. That way the ePub object is globally available and can be used in Typescript after declaring it with declare var ePub: any;.
