Hybrid Mobile Development with Ionic

By: Gaurav Saini

Overview of this book

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. This book will help you to develop a complete, professional and quality mobile application with Ionic Framework. You will start the journey by learning to configure, customize, and migrate Ionic 1x to 3x. Then, you will move on to Ionic 3 components and see how you can customize them according to your applications. You will also implement various native plugins and integrate them with Ionic and Ionic Cloud services to use them optimally in your application. By this time, you will be able to create a full-fledged e-commerce application. Next, you will master authorization, authentication, and security techniques in Ionic 3 to ensure that your application and data are secure. Further, you will integrate the backend services such as Firebase and the Cordova iBeacon plugin in your application. Lastly, you will be looking into Progressive Web Applications and its support with Ionic, with a demonstration of an offline-first application. By the end of the book, you will not only have built a professional, hybrid mobile application, but will also have ensured that your app is secure and performance driven.

Demonstrating authorization in Ionic

Let's now build an Ionic application that will handle both authentication and authorization. Authorization refers to rules that determine who is allowed to do what. Authentication and authorization are central parts of securing an application:

Authentication = login + password (who you are)

Authorization = permissions (what you are allowed to do)

In this section, we will see how we can secure views of the Ionic application that are login protected. We will be working on the following points:

  • HomePage will be public
  • ArticlesPage is protected and will only be accessed after login
  • Menu is also dynamically updated on auth status
  • LoginPage will be inaccessible once a user is loggedIn
  • Authorization header will be passed after login for each request

Let's start by creating the application and I have named it as ionic2-auth:

    $ ionic start ionic2-auth sidemenu -v2
$ ionic...
