Getting Started With Angular
Getting Started With Angular
About the Book
Angular is a well-established front-end framework and this book will guide you through how to get started with Angular.
This book is over 11 chapters, taking you from introducing you to what Angular is and the benefits of using Angular for your next web application project. To going through how an Angular application is structured, how it makes use of Components, templates and services. Then moving onto how we can make use of the Angular CLI to help build parts of our application.
Once we have an understanding of what Angular is and how it’s structured we will go through more advanced features like writing Services to access external APIs. Then we will go through Observables and Observer, seeing what they are and how they can be used within our Angular applications.
We will look at RxJs and NgRx, how these two libraries can be used with Angular to tackle state management within an application. Finally, we will look at how to write Unit Tests and how to use the Angular CLI to create a production-ready version of an application.

C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.
