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.

Discovering the any and platform provider scopes

Tree-shakable providers make it possible to create dependencies that are removed from a compiled bundle if they have not been unused. This is especially important for Angular libraries, but it also plays a role in large Angular applications and monorepositories that contain multiple Angular applications.

As an experienced Angular developer, you are probably already familiar with the root provider scope shorthand, which can be passed to the providedIn option in the Injectable decorator factory, and the InjectionToken constructor. It is used to create an application-wide singleton dependency.

Angular version 9 introduced two new provider scope shorthands, namely any and platform. In this section, we are going to discuss any, which is the most complex of the two provider scope shorthands.

The any provider scope

The any provider scope declares a singleton dependency per module injector. This means that the root module –...
