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.

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 we 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 WorldCities and WorldCitiesAPI projects in debug mode – or right-click the WorldCitiesAPI project and select...
