ASP.NET Core 6 and Angular - Fifth Edition

By: Valerio De Sanctis

Overview of this book

Every full-stack ninja needs the tools to operate on front-end and back-end application development. This web app development book takes a hands-on, project-based approach to provide you with all the tools and techniques that web developers need to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. The fifth edition has been updated to cover advanced topics such as Minimal APIs, Web APIs with GraphQL, real-time updates with SignalR, and new features in .NET 6 and Angular 13. You begin by building a data model with Entity Framework Core, alongside utilizing the Entity Core Fluent API and EntityTypeConfiguration class. You'll learn how to fetch and display data and handle user input with Angular reactive forms and front-end and back-end validators for maximum effect. Later, you will perform advanced debugging and explore the unit testing features provided by (.NET 6) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications, learning about their technical requirements, testing processes, and how to convert a standard web application to a PWA. By the end of this web development book, you will understand how to tie together the front-end and back-end to build and deploy secure and robust web applications.

Two players, one goal

From the perspective of a fully functional web-based application, we can say that the Web API interface provided with the ASP.NET framework is a programmatic set of server-side handlers used by the server to expose a number of hooks and/or endpoints to a defined request-response message system. This is typically expressed in structured markup languages (XML), language-independent data formats (JSON), or query languages for APIs (GraphQL). As we’ve already said, this is achieved by exposing application programming interfaces (APIs) through HTTP and/or HTTPS protocols via a publicly available web server such as IIS, Node.js, Apache, or NGINX.

Similarly, Angular can be described as a modern, feature-rich, client-side framework that pushes the HTML and ECMAScript’s most advanced features, along with the modern browser’s capabilities, to their full extent by binding the input and/or output parts of an HTML web page into a flexible, reusable, and easily testable model.

Can we combine the back-end strengths of ASP.NET and the front-end capabilities of Angular in order to build a modern, feature-rich, and highly versatile web application?

The answer, in short, is yes. In the following chapters, we’ll see how we can do that by analyzing all the fundamental aspects of a well-written, properly designed, web-based product, and how the latest versions of ASP.NET and/or Angular can be used to handle each one of them. However, before doing all that, it might be very useful to backtrack a bit and spend some valuable time recollecting what’s happened in the last 8 years in the development history of the two frameworks we’re going to use. It will be very useful to understand the main reasons why we’re still giving them full credit, despite the valuable efforts of their ever-growing competitors.
