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.

Fetching data

As we already know from Chapter 2, Getting Ready, reading data from the database is mostly a matter of having the Angular app (the front-end) send HTTP requests to the ASP.NET app (the back-end) and fetching the corresponding HTTP responses accordingly; these data transfers will be mostly implemented using JavaScript Object Notation (JSON), a lightweight data-interchange format that is natively supported by both frameworks.

In this section, we’ll mostly talk about HTTP requests and responses, see how we can fetch data from the ASP.NET app, and lay out some raw UI examples using Angular components that will be further refined throughout the next sections.

Are you ready? Let’s start!

Requests and responses

Let’s start by taking a look at those HTTP requests and responses we’ll be dealing with. Hit F5 to launch both the worldcities.client and WorldCities.Server projects in debug mode – or right-click the WorldCities.Server...
