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.

It was a long read, but this introduction to TypeScript was necessary to understand the logic behind many of the most brilliant parts of Angular. It gave us the chance to introduce the language syntax and explain the rationale behind its success as the syntax of choice for building the Angular framework.

We reviewed the type architecture and how we can create advanced business logic when designing functions with various alternatives for parameterized signatures. We even discovered how to bypass scope-related issues using the powerful arrow functions. We enhanced our knowledge of TypeScript by exploring some of the most common features used in Angular applications.

Probably the most relevant part of this chapter encompassed our overview of classes, methods, properties, and accessors and how we can handle inheritance and better application design through interfaces. Modules and decorators were some other significant features we explored in this chapter. As we will see very soon, having sound knowledge of these mechanisms is paramount to understanding how dependency injection works in Angular.

With all this knowledge at our disposal, we can start learning how to apply it by building Angular applications. In the next chapter, we will learn how to use Angular modules, which are not the same as JavaScript modules, to structure an Angular application. We will see in detail what Angular modules are and how we can use them to organize an Angular application in an efficient and properly structured way.
