Angular 2 Components

By: Thierry Templier Thierry

Overview of this book

This book is a concise guide to Angular 2 Components and is based on the stable version of Angular 2. You will start with learning about the Angular 2 Components architecture and how components differ from Angular directives in Angular 1. You will then move on to quickly set up an Angular 2 development environment and grasp the basics of TypeScript. With this strong foundation in place, you will start building components. The book will teach you, with an example, how to define component behavior, create component templates, and use the controller of your component. You will also learn how to make your components communicate with each other. Once you have built a component, you will learn how to extend it by integrating third-party components with it. By the end of the book, you will be confident with building and using components for your applications.

About the Reviewers


In Angular 2, a component is a class with a decorator that adds important metadata to it. The component decorator defines how we can use it, and what it can do. The selector and the template are the minimum required fields when calling the decorator (Angular will throw an error if one of them is missing).

If we defined the view encapsulation as native, Angular will create a shadow DOM for our component, which protects the embedded styles from being affected by external CSS on the page.

In the next chapter, we will continue to develop our component and make it dynamic.
