Overview of this book

Writing clean, object-oriented code in JavaScript gets trickier and complex as the size of the project grows. This is where Typescript comes into the picture; it lets you write pure object-oriented code with ease, giving it the upper hand over JavaScript. This book introduces you to basic TypeScript concepts by gradually modifying standard JavaScript code, which makes learning TypeScript easy for C# ASP.NET developers. As you progress through the chapters, you'll cover object programming concepts, such as classes, interfaces, and generics, and understand how they are related to, and similar in, both ES6 and C#. You will also learn how to use bundlers like WebPack to package your code and other resources. The book explains all concepts using practical examples of ASP.NET Core projects, and reusable TypeScript libraries. Finally, you'll explore the features that TypeScript inherits from either ES6 or C#, or both of them, such as Symbols, Iterables, Promises, and Decorators. By the end of the book, you'll be able to apply all TypeScript concepts to understand the Angular framework better, and you'll have become comfortable with the way in which modules, components, and services are defined and used in Angular. You'll also have gained a good understanding of all the features included in the Angular/ASP.NET Core Visual Studio project template.

Project structure

The whole Angular Client application is contained in the ClientApp folder. This folder contains various configuration files and two folders that define two Angular applications:

The src folder contains the main application to publish, while the e2e folder contains an application whose only purpose is the execution of end-to-end tests on the main applications. End-to-end tests are integration tests that also simulate actual user interaction with the application. Ends-to-end tests are based on the Protractor framework which will be described in the Testing section of Chapter 13, Navigation and Services.

The following is a descriptions of all configuration files contained in the ClientApp folder:

  • Angular.json: This is the main Angular configuration file. Here, the developer may configure how the application is built, and how WebPack bundles all application assets...
