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 Authors
About the Reviewers


Angular 2 is a leap forward from the previous Angular 1.x framework, which became the most popular frontend JavaScript framework in history.

It is a complete re-write, an up-to-date platform that is built upon web standards and modern APIs. With Angular 2, you can build JavaScript applications aimed at the browser, server, mobile, and desktop, thanks to an architecture that decoupled the view layer of Angular from the platform core and services.

This book will be focused on the UI layer of Angular: components. We will explore the rich API and multiple options available for building and composing UI components for powerful user interfaces and views.

A block of code is set as follows:

class Product {
  private id: number;
  private color: string;

  constructor(id:number, color:string) { = id;
    this.color = color;

Any command-line input or output is written as follows:

$ npm uninstall -g angular-cli
$ npm cache clean
