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.

selectors and 

properties you can use to style UI components.

of all UI

.btn {
  font-size: 18;

In many cases you may want to use the NativeScript core theme instead
of writing your own CSS rules. For a full list 

of class names in the theme

@import 'nativescript-


Out of the box, the --ng template hints at two options you could choose from to build out your CSS:

  • Write your own custom classes
  • Utilize the nativescript-theme-core styling framework plugin as your base
