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.

If we take a look at our current .NET Core with Angular projects, we will see how none of them allow our users to interact with the data:

  • For the HealthCheck app, this is expected since there’s simply no data to deal with: this is a monitor app that doesn’t store anything and requires no input from the user
  • The WorldCities app, however, tells a whole different story: we do have a database that we use to return results to our users, who could — at least theoretically— be allowed to make changes

It goes without saying that the WorldCities app would be our best candidate for implementing our forms. In the following sections, we’ll do just that, starting with the Angular project (the front-end) and then moving to the ASP.NET Core Web API project (the back-end).

Forms in Angular

Let’s take a minute to briefly review our WorldCities app in the state we left it in at the end of Chapter 6,...
