Overview of this book

As Angular continues to reign as one of the top JavaScript frameworks, more developers are seeking out the best way to get started with this extraordinarily flexible and secure framework. Learning Angular, now in its fourth edition, will show you how you can use it to achieve cross-platform high performance with the latest web techniques, extensive integration with modern web standards, and integrated development environments (IDEs). The book is especially useful for those new to Angular and will help you to get to grips with the bare bones of the framework to start developing Angular apps. 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. Updated for Angular 15, this new edition covers lots of new features and tutorials that address the current frontend web development challenges. You’ll find a new dedicated chapter on observables and RxJS, more on error handling and debugging in Angular, and new real-life examples. 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.

Summary

Enterprise web applications must exchange information with a backend API almost daily. The Angular framework enables applications to communicate with an API over HTTP using the built-in HTTP client. In this chapter, we explored the essential parts of the Angular HTTP client.

We learned how to move away from the traditional fetch API and use observables to communicate over HTTP. We explored the basic parts of a CRUD application using the Fake Store API as our backend. We investigated how to implement authentication and authorization in Angular applications. Finally, we learned what Angular interceptors are and how we can use them to authorize HTTP calls.

Now that we know how to consume data from a backend API in our components, we can further improve the user experience of our application. In the next chapter, we will learn how to load our components through navigation using the Angular router.
