NativeScript for Angular Mobile Development

By: Nathan Walker, Nathanael J. Anderson

Overview of this book

NativeScript is an open source framework that is built by Progress in order to build truly native mobile apps with TypeScript, JavaScript or just Angular which is an open source framework built by Google that offers declarative templates, dependency injection, and fully featured modules to build rich applications. Angular’s versatile view handling architecture allows your views to be rendered as highly performant UI components native to iOS and Android mobile platforms. This decoupling of the view rendering layer in Angular combined with the power of native APIs with NativeScript have together created the powerful and exciting technology stack of NativeScript for Angular. This book focuses on the key concepts that you will need to know to build a NativeScript for Angular mobile app for iOS and Android. We’ll build a fun multitrack recording studio app, touching on powerful key concepts from both technologies that you may need to know when you start building an app of your own. The structure of the book takes the reader from a void to a deployed app on both the App Store and Google Play, serving as a reference guide and valuable tips/tricks handbook. By the end of this book, you’ll know majority of key concepts needed to build a successful NativeScript for Angular app.

Phase 1 – Building an audio recorder for iOS

The audio capabilities of the iOS platform are impressive, to say the least. A group of wonderfully talented audiophiles and software engineers have collaborated on building an open source framework layer on top of the platform's audio stack. This world class engineering effort is the awe inspiring AudioKit (, led by the fearless Aurelius Prochazka, a true pioneer in audio technology.

The AudioKit framework is written entirely with Swift, which introduces a couple of interesting surface-level challenges when integrating with NativeScript.

Challenge detour – Integrate Swift based library into NativeScript 

At the time of this writing, NativeScript can work with Swift if the codebase properly exposes the classes and types to Objective-C via what's called a bridging header, allowing both the languages to be mixed or matched. You can learn more about what a bridging header is here:
