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 9: Debugging with the New Ivy Runtime APIs

Angular Ivy introduces a new API for inspecting and debugging our Angular applications at runtime. It replaces the previous NgProbe API and allows tree-shaking of DebugElement.

We will explore Angular's most useful runtime debugging functions, including the following:

  • ng.applyChanges
  • ng.getComponent
  • ng.getContext
  • ng.getListeners

Having these debugging utilities at hand will allow you to verify your assumptions about active components, their templates, and their DOM bindings at runtime.

This chapter covers these topics:

  • Introduction to the new Ivy runtime API
  • Inspecting an active component
  • Inspecting event listeners
  • Inspecting an embedded view context

Getting familiar with these topics will improve your development workflow when implementing Angular Ivy applications.
