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.

The Model-View-Controller pattern


This is an architectural design pattern for implementing user interfaces, which has been used for many years for desktop GUI.

It divides the application into three distinct parts:

  • Model: This is responsible for storing the actual data

  • View: This is the presentation layer that renders the data to the user

  • Controller: The glue between the model and the view

The following diagram describes the relationships between those parts:

This pattern describes the communication between those parts. The view reflects the data in the model, but cannot alter the data directly in the model. It is common to describe the relationship between the model and the view as read only (the view can only read from the model). The view uses the controller by invoking methods and changing attributes. The controller updates the model, which causes the view to update and render the new data.

MVC, which was originally developed for desktop applications, has been widely adopted as an architecture for building single page web applications and can be found in all the popular client-side frameworks, including Angular.
