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.

When creating a new Angular application, the first step is to define the different features our application needs. We should remember that each one should make sense on its own in isolation from the others. Once we’ve defined the required features, we will create a module for each. Each module will then be filled with the Angular artifacts that shape the feature it represents. Always remember the principles of encapsulation and reusability when defining your feature set.

If we wanted to create an e-shop application, we would typically need a module to manage the stock of our products. To create a new module in an Angular application, we use the generate command of the Angular CLI, passing the name of the module as a parameter:

ng generate module products

The preceding command will create a products folder inside the src\app folder of our Angular workspace. The products folder is the container for Angular artifacts...
