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.

Summary

I hope you like the new shiny tools that we added to your toolbox in this chapter. We started with an overview of Angular Ivy's runtime debugging API, which is available only in development mode.

Next, we learned how to inspect a component instance using ng.getComponent and ng.getOwningComponent. We also changed the component state, then updated the DOM using ng.applyChanges.

In the Inspecting event listeners section, we used ng.getListeners to inspect both native DOM event listeners and custom component event listeners. We passed arguments to their callbacks and triggered change detection using ng.applyChanges.

Finally, you now know what an embedded view context is and how to inspect it, for example, how one is created and bound to each component or element managed by the NgFor directive. Similarly, we explored an example of an embedded view context for an element managed by an NgIf directive.

With all these newfound skills, you are ready to debug Angular...
