Angular 2 Components

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.

Preparing our development environment

It's time to create a new project with angular-cli as described in Chapter 2, Setting Up an Angular 2 Development Environment with angular-cli. We will create a new directory called components to contain all the components we will implement in this chapter.

We will later create two other subdirectories in this chapter, accordion and user-info, when implementing the corresponding components:

The last thing before starting to build our new components is to clean up our root component. Open index.ts and clean it as follows:

import { Component } from '@angular/core';

  selector: 'app-root',
  template: '<h1>Angular2 Components</h1>'
export class AppComponent {}

Open your browser and make sure that the component has rendered without any errors:

Now we are ready to start developing our new components.
