I have written a range of paid books that cover a variety of Ionic topics from the basics of getting started and building applications, to creating your own complex interactions and animations.
All of these books offer a large amount of value and were written with care to ensure a high quality product. Updates are always released for free, even years after the initial launch, and if you are unsatisfied with any book there is a 14-day no questions asked refund policy.
All books are available in PDF, ePub, and mobi formats. I have marked each book with BEGINNER, INTERMEDIATE, and ADVANCED to give an indication of the pre-requisite skill level required.
