Overview of this book

Are you are looking for a better, more efficient, and more powerful way of building front-end web applications? Well, look no further, you have come to the right place! This book comprehensively integrates Angular version 4 into your tool belt, then runs you through all the new options you now have on hand for your web apps without bogging you down. The frameworks, tools, and libraries mentioned here will make your work productive and minimize the friction usually associated with building server-side web applications. Starting off with building blocks of Angular version 4, we gradually move into integrating TypeScript and ES6. You will get confident in building single page applications and using Angular for prototyping components. You will then move on to building web services and full-stack web application using ASP.NET WebAPI. Finally, you will learn the development process focused on rapid delivery and testability for all application layers.

TypeScript and Angular

As you have seen in this chapter, TypeScript comes with strong type-checking capabilities and supports object-oriented programming. Due to such advantages, the Angular team has chosen TypeScript to build Angular. Angular was completely rewritten from the core using TypeScript, and its architecture and coding pattern was completely changed, as you saw in Chapter 2, Angular building blocks part 1, and Chapter 3, Angular building blocks part 2. So, writing an Angular app using TypeScript is the best choice.

We can implement modules in Angular similar to modules in TypeScript. Components in an Angular application are actually a TypeScript class decorated with @Component. Modules can be imported to the current class file using import statements. The export keyword is used to indicate that this component can be imported and accessed in another module. The sample component code that is developed using TypeScript is as follows:

import {Component} from '@angular/core'
