Overview of this book

Angular, loved by millions of web developers around the world, continues to be one of the top JavaScript frameworks thanks to its regular updates and new features that enable fast, cross-platform, and secure frontend web development. With Angular, you can achieve high performance using the latest web techniques and extensive integration with web tools and integrated development environments (IDEs). Updated to Angular 10, this third edition of the Learning Angular book covers new features and modern web development practices to address the current frontend web development landscape. If you are new to Angular, this book will give you a comprehensive introduction to help you get you up and running in no time. You'll learn how to develop apps by harnessing the power of the Angular command-line interface (CLI), write unit tests, style your apps by following the Material Design guidelines, and finally deploy them to a hosting provider. The book is especially useful for beginners to get to grips with the bare bones of the framework needed to start developing Angular apps. By the end of this book, you’ll not only be able to create Angular applications with TypeScript from scratch but also enhance your coding skills with best practices.

Introducing the Angular router

In traditional web applications, when we wanted to change from one view to another, we needed to request a new page from the server. The browser would create a URL for the view and send it to the server. As soon as a response was received from the server, the browser would reload the page. This was a process that resulted in round trip time delays and a bad user experience for our applications:

Modern web applications that use a JavaScript framework such as Angular follow a different approach. They handle changes between views or components on the client side without bothering the server. They contact the server only once during bootstrapping to get the main index.html file. Any subsequent URL changes are intercepted and handled by the router on the client. These types of applications are called Single-Page Applications (SPA) because they do not cause a full reload of a page...
