Foreword
This book is the result of 7 months of focused writing and coding by Hoc Phan, a talented
developer and dedicated writer with whom the Ionic team has collaborated on a past book.
Hoc is a dedicated Ionic community member who often speaks about Ionic, and we have the
utmost respect for his commitment to teaching others how to use Ionic in really effective
ways. This book provides recipes for getting a stew goin' with Ionic!
Hoc teaches developers how to set up a project by installing the Ionic command-line tool
(CLI) and creating a new project. He addresses platform-specific styles and how to target each
platform with SCSS and JavaScript. He explains how to integrate an Ionic app with Firebase
to create a connection to a real-time database. The book covers routing and navigation, as
well as running your app on a device (how to target the iOS and Android simulators).
For more advanced developers, the book explains how to integrate device APIs with ngCordova
by working with a device's camera. Hoc also addresses the topic of setting up the Whitelist
Plugin and working with CSP to make sure your app is secure.
Before I joined Ionic as a core team member and developer advocate, I was a developer and
created many internal hybrid apps for my company. Before I began building apps, I evaluated
multiple frameworks. Only Ionic provided a complete solution for hybrid mobile development.
I could focus on development, and Ionic handled architecture and design.
Ionic offers a complete ecosystem for building performant, beautiful mobile apps using one
code base, which saves time and money. We released the stable version of Ionic in May
2015 and have released alpha versions of four of our platform services since then. We
plan to continue to support the open source Ionic SDK and release new features, tools, and
services. As Ionic's developer advocate, I travel around the US to talk about Ionic and meet
Ionic developers, and my favorite part of my job is people's enthusiasm for Ionic. The Ionic
community is what makes Ionic great.
You'll find this book to be a great way to get cooking with Ionic and deep dive into the
SDK. We're glad to have you as a member of the Ionic community.
Enjoy!

on many JavaScript projects in the past by teaching himself the framework using various
online sources. He was one of the first few developers who tested Ionic for its feasibility
as a JavaScript replacement of the native language of a device. He wrote the Full Stack
Mobile App with Ionic Framework book (for more information, visit http://www.amazon.

very well-received.
He has worked for both start-ups and large companies. By frequently speaking at local
meet-ups as well as cloud computing / Big Data industry events and conferences,
he learns from other experts. He holds an MBA degree from the University of Washington's
Michael G. Foster School of Business.

Preface
The world of mobile development is fragmented, with many platforms, frameworks, and
technologies. Ionic is intended to fill this gap with its open source HTML5 mobile app framework
that lets developers build native-feeling apps using web technologies such as HTML, CSS, and
AngularJS. Ionic makes it easy for frontend developers who want to become app developers.
The framework provides superior performance with deep Cordova integration and a
comprehensive set of tools for prototyping, backend support, and deployment.
This book will take you through the process of developing a cross-platform mobile app using
just HTML5 and JavaScript based on Ionic. You will start first by getting familiarized with the
CLI and learning how to build and run an app. You will have a look at some common features
of real-world mobile apps such as authenticating a user and receiving and saving data using
either Firebase or Local Storage.
Next, the book will explain how Ionic integrates with Cordova to support native device features
by using ngCordova and takes advantage of the existing modules around its ecosystem. You
will also explore the advanced topics related to extending Ionic to create new components.
Finally, the book will show you how to customize the Ionic theme and build the app for all
platforms.

What this book covers
Chapter 1, Creating Our First App with Ionic, introduces the Ionic framework and provides
instructions for setting up the development environment and quickly creating and running
the first app.
Chapter 2, Managing States and Navigation, walks through some examples of how to
manage views, states, and the overall navigation within the app. This can be done via
either the UI-Router component of AngularJS or the out-of-the-box Ionic directives.
Chapter 3, Adding Device Features Support, explains how to use ngCordova to access native
device functionalities such as the camera (photo and video), the contact list, e-mail, and map.
iii



Preface
Chapter 4, Offline Data Storage, explains how to work with persistent data when the device
is offline. You will understand the advantages and disadvantages of using Local Storage
versus SQLite.
Chapter 5, Handling Gestures and Events, explains how a touch event works and how to
process these events to create a better interaction or a custom component.
Chapter 6, App Theme Customization, provides instructions on how to customize an app for
different platforms and create an introduction screen for your own branding.
Chapter 7, Extending Ionic with Your Own Components, takes a deep dive into the AngularJS
directive and filter customization. You will learn how to leverage events from the core Ionic
components and use requestAnimationFrame for an improved animation performance.
Chapter 8, User Registration and Authentication, explains the different methods that can be
used to authenticate a user and how the Firebase authentication system works.
Chapter 9, Saving and Loading Data Using Firebase, walks through some examples,
such as those related to storing and retrieving data, using Firebase as the backend.
Also, you will learn how to manage and render large datasets.
Chapter 10, Finalizing Your Apps for Different Platforms, provides instructions for
performing the final steps of getting an app published.
