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.

Sharing information across application boundaries using the platform provider scope

We can demonstrate how to share information outside of the app by creating a tweet button as an Angular element. This Angular element could be used outside of the app as well. Let's dig into the details on how to do that.

First, we will start by adding Angular elements to the app by running the following command:

ng add i @angular/elements

Then we include the Twitter widgets SDK within the page like this:

  <script
      src="https://platform.twitter.com/widgets.js"
      type="text/javascript"
    ></script

Then we can build a tweet hashtag button using a TweetCourse component like this:

<ng-container *ngIf="course$ | async as course">
  <a
    href="https://twitter.com/intent/tweet?button_hashtag= &...
