Preface

This book teaches you how to master in hybrid mobile development using Ionic. Ionic is an open source, front-end framework that allows you to develop hybrid mobile apps without any native-language hassle for each platform. It offers a library of mobile-optimized HTML, CSS, and JS components for building highly interactive mobile apps.

Initial idea to write this book is to help understand developers what is the building blocks and necessary points to look for while you are developing an enterprise level or highly scalable Ionic application. Also, in the later half of the book we will target some latest features in Ionic such as IOT and PWA support. We have made sure that every concept addressed in this book is explained in easy language, and also with a technical example.

What this book covers

Chapter 1, Getting Started with Ionic 3, we will be going through all the essentials of Ionic, which will help in building large scale and enterprise grade applications.

Chapter 2, Ionic Components, will guide you towards Ionic components and how we can customize them according to our applications.

Chapter 3, Ionic Native and Plugins, covers almost everything regarding Cordova plugins, Ionic Native and some common and advance plugins. 

Chapter 4, Ionic Platform and Services, covers all the Ionic Platform services and how to use them in best way in your application.

Chapter 5, Authentication, Authorization, and Security, will be dealing with authentication, securing Ionic application and demonstrating authorization.

Chapter 6, TasteBite App with Firebase, focuses on building entire application from start to end by using Backend as a Service platform Firebase.

Chapter 7, Ionic, IOT and Beacons, we will be discussing about IOT, BLE and Physical Web. Besides this will demonstrate ibeacon based proximity application where your laptop will screen lock as soon as you will move away from your laptop.

Chapter 8, Ionic + PWA = Magic, we will be looking into Progressive Web Applications and its support with Ionic with a demonstration of offline-first currency converter application.

What you need for this book

You’ll need Sublime or Visual Studio Code for code editing. Both of these are available free for download. For BLE demo you will need a laptop with Bluetooth 4 supported or Bluetooth BLE beacon.

Who this book is for

This book is for intermediate-level application developers who have some basic knowledge of Ionic. Those who want to migrate their applications from Ionic 1 to Ionic 3 this book will be very helpful and who want to get latest technology updates such as PWA support with Ionic.

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "For setting up the APIs endpoints we have created constants file where we declared constant API_URL"

A block of code is set as follows:

{
  "name": "ionic2-auth",
  "app_id": "",
  "v2": true,
  "proxies": [
  {
   "path": "/api",
   "proxyUrl": "http://yourwebsite.com /api"
  } 
 ]
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

// src/providers/constants.ts
// While deploying application we switch to real URL

export const API_URL: string = 'http://localhost:8100/api';

Any command-line input or output is written as follows:

$ chromium-browser –disable-web-security

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Cancel and OK buttons. We have used this here for sorting the products according to relevance price or other sorting values."
