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.

Performing manual Angular Ivy migrations

In this section, we will walk through optional migrations that put our application on track for future Angular versions. We will discuss fine-tuning initial navigation, optimizing change detection with NgZone, and improving the type safety of our unit tests.

Managing initial navigation

The following legacy values for the initialNavigation option for RouterModule.forRoot are removed by Angular Ivy version 11:

  • true
  • false
  • 'legacy_enabled'
  • 'legacy_disabled'

Angular Ivy version 11 also deprecates the 'enabled' value but introduces the following new values:

  • 'enabledBlocking'
  • 'enabledNonBlocking' (default)

'enabledBlocking' is equivalent to 'enabled' and is recommended for server-side rendering using Angular Universal. This value starts the initial navigation process before Angular creates an instance of the root component of our...
