By: Aristeidis Bampakos, Pablo Deeleman

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.

At this point, we have set up the route configuration so that routing works the way it should. However, this approach doesn't scale so well. As our application grows, more and more routes may be added to AppRoutingModule. Thus, we should create a separate feature module for our components that will also have a dedicated routing module.

We have already learned how to create a new Angular module in Chapter 5, Structure an Angular App. We will use the same generate Angular CLI command, but we will pass a different option to create the routing module as well:
