This book comes with a code bundle that is available at https://github.com/kerrishotts/Mastering-PhoneGap-Code-Package. If you haven't downloaded it yet, I strongly advise you to do so. It contains all the code for each chapter as well as lots of snippets that demonstrate some of the examples in most chapters. Furthermore, the chapters in the book focus mostly on snippets—to see the topics in use in an actual application, you'll definitely want to look at the demonstration app's code.
Before continuing with this chapter, ensure that you have met the pre-requisites as listed in this book's preface. Software and hardware requirements are also listed in the code package for this book in the README.md file.
If you want to build and deploy the demonstration application from the code bundle, you'll need to install the earlier mentioned tools. Because the Cordova projects and platform-specific files are considered build artifacts, you'll need to execute the following in each chapter's directory in order to build each version of the app:
# On Linux / Mac OS X (using Bash shell) $ npm install && gulp init % On Windows > npm install > gulp init
