Overview of this book

Hybrid Apps are a promising choice in mobile app development to achieve cost effectiveness and rapid development. However, they were not preferred over native apps until few years back due to a poor performance and bad user experience, but everything has changed with the release of Ionic. It has evolved as the most popular choice for Hybrid Mobile App development as it tends to match the native experience and provides robust components/tools to build apps. Getting Started with Ionic equips any web developer with the basic knowledge needed to use modern web technologies to build amazing hybrid mobile apps using Ionic. This fast-paced, practical book explains all the important concepts of AngularJS and Cordova Framework required to develop apps, then gives you a brief introduction to hybrid mobile applications.

Cordova ensures that Hybrid Apps harness the power and performance of native code perfectly. Cordova plugins utilize this power and enable us to use the specific device features in JS easily.

Cordova from version 3 and above decided to expose all device APIs as plugins. The Cordova plugin is a reusable set of code that contains the native code as well as JavaScript code. We know that our web app runs inside a WebView control in Ionic/Cordova Apps.
