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.

Chapter 5: Structure an Angular App

We have reached a point in our journey where we can successfully develop more complex applications by nesting components within other components, in a sort of component tree. However, bundling all our business logic into a single component is not the way to go. Our application might become unmaintainable very soon. Later in this chapter, we'll investigate the advantages that Angular's dependency management mechanism can bring to the game to overcome such problems.

In this chapter, we will learn how to build application architectures based on trees of components and organize them into modules. We will also learn about the new Angular dependency injection mechanism, which helps us to declare and consume our dependencies across the application with minimum effort and optimal results. By the end of this chapter, you will be able to create an Angular application that is correctly structured to enforce separation of concerns using modules...
