ASP.NET Core 5 and Angular - Fourth Edition

By: Valerio De Sanctis

Overview of this book

Learning full-stack development calls for knowledge of both front-end and back-end web development. ASP.NET Core 5 and Angular, Fourth Edition will enhance your ability to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. This revised edition includes coverage of the Angular routing module, expanded discussion on the Angular CLI, and detailed instructions for deploying apps on Azure, as well as both Windows and Linux. Taking care to explain and challenge design choices made throughout the text, Valerio teaches you how to build 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 xUnit.net (.NET 5) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications (PWAs), learning about their technical requirements, testing, and converting SWAs to PWAs. 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.

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 front-end and then moving to the .NET Core 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 5, Fetching and Displaying Data. If we take a look...
