My latest book, Apache Cordova 3 Programming, is now available at Apache Cordova 3 Programming | InformIT. The book is a rewrite of the first half (the tools portion) my PhoneGap Essentials plus coverage on how to create Cordova plugins plus some high-level coverage of the Cordova APIs. It provides complete coverage of the Cordova CLI and the tools a developer uses to build Cordova applications. There’s even a chapter that talks about the SAP Mobile Platform and Kapsel (SAP’s plugins for Apache Cordova).
If you would like to read part of the book, Chapter 6, the Mechanics of Cordova development was made available yesterday as a free PDF. You can find the file here: http://ptgmedia.pearsoncmg.com/images/9780321957368/samplepages/0321957369.pdf.
