Overview of this book

Angular Ivy is the latest rendering engine and compiler introduced in Angular. Ivy helps frontend developers to make their Angular applications faster, better optimized, and more robust. This easy-to-follow guide will help you get to grips with the new features of Angular Ivy and show you how to migrate your Angular apps from View Engine to Ivy. You'll begin by learning about the most popular features of Angular Ivy with the help of simple stand-alone examples and realize its capabilities by working on a real-world application project. You'll then discover strategies to improve your developer workflow through new debugging APIs, testing APIs, and configurations that support higher code quality and productive development features. Throughout the book, you'll explore essential components of Angular, such as Angular Component Dev Kit (CDK), Ahead-of-time (AOT) compilation, and Angular command line interface (CLI). Finally, you'll gain a clear understanding of these components along with Angular Ivy which will help you update your Angular applications with modern features. By the end of this Angular Ivy book, you will learn about the core features of Angular Ivy, discover how to migrate your Angular View Engine application, and find out how to set up a high-quality Angular Ivy project.

Chapter 8: Additional Provider Scopes

This chapter seeks to explain how to use dependency injection scopes to develop more lean components and features in Angular Ivy. To explore these features, we will learn how to create a non-singleton service and how to reuse dependencies across Angular elements.

We will introduce the any provider scope by revising the theme service so that it can accept specific configurations when used in different scenarios using the any provider scope and rewiring the schools and course modules to be lazy loaded.

We will then wrap up Part 2, Build a Real-World Application with the Angular Ivy Features You Learned by building a new login element that shows how to share information across application boundaries by using the platform provider scope for Angular Elements.

We will cover the following topics in this chapter:

  • Revisiting the root provider scope
  • Using the any provider scope for a configurable theme service
  • Sharing information...
