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.

We will now look into Firebase user authentication and how we can secure our data. Firebase supports login and authentication internally and also provides support for integrating with social login providers.

Whenever we login using Firebase a session is created and a unique ID uid is returned by Firebase, which is distinct across all providers and never change for a specific authenticated user. This will also help us later in securing our data.

Once the user is authenticated its session is managed and remembered even after the application is restarted. Firebase provides user authentication for multiple platforms:

  • Custom - for integrating with existing authentication systems
  • E-mail - register and authenticate users by e-mail and password.
  • Anonymous - for guest...
