Overview of this book

If you want to learn how to use ASP.NET Core with Angular effectively, this hands-on guide is for you. Improve the way you create, debug, and deploy web applications while keeping up to date with the latest developments in .NET 8 and modern Angular, including .NET Minimal APIs and the new Angular standalone API defaults. You’ll begin by setting up SQL Server 2022 and building a data model with Entity Framework Core. You’ll progress to fetching and displaying data, handling user input with Angular reactive forms, and implementing front-end and back-end validators for maximum effect. After that, you will perform advanced debugging and explore unit testing features with xUnit for .NET, and Jasmine and Karma for Angular. You’ll use Identity API endpoints in ASP.NET Core and functional route guards in Angular to add authentication and authorization to your apps. Finally, you’ll learn how to deploy to Windows, Linux, and Azure. By the end of this book, you will understand how to tie together the front-end and back-end to build and deploy secure and robust web applications.

Preface

ASP.NET Core is a free, open-source, modular web framework developed by Microsoft. It operates on top of the full .NET Framework on Windows or .NET Core on cross-platform compatibility. Specifically designed for the efficient creation of HTTP services, it caters to a wide array of clients, including web browsers, mobile devices, smart TVs, and web-based home automation tools.

Angular is the successor of AngularJS, a world-renowned development framework born to equip coders with the necessary tools for building reactive, cross-platform web applications optimized for both desktop and mobile environments. It features a structure-rich template approach based on a natural, easily writable, and readable syntax.

Technically, ASP.NET Core and Angular share little in common. ASP.NET Core primarily focuses on server-side web development, while Angular addresses client-side aspects such as the User Interface (UI) and User Experience (UX). However, both frameworks emerged from a shared vision: utilizing the HTTP protocol not just for serving web pages but as a platform for building web-based APIs that efficiently send and receive data. This concept, emerging over the first two decades of the World Wide Web, is now a widely accepted foundation of modern web development.

The compelling reasons behind this shift in perspective are many, but the most important is the intrinsic characteristics of the HTTP protocol. Its simplicity, flexibility, and universality make it suited to the diverse needs of the ever-evolving World Wide Web. Nowadays, almost any platform that we can think of has an HTTP library, so HTTP services can reach a broad range of clients, from browsers and IoT devices to desktop applications and video games.

The main purpose of this book is to bring together the latest versions of ASP.NET Core and Angular into a single development. This combination demonstrates how to create high-performance web applications and services accessible to a wide range of clients, seamlessly blending server and client-side functionalities.
