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.

Testing the PWA capabilities

In this section, we’ll try to test the service worker registration for our HealthCheck app. Unfortunately, doing it from a Visual Studio development environment is a rather complex task for several reasons, including the following:

  • ng serve, the Angular CLI command that pre-installs the packages and starts the app whenever we run our app in debug mode, doesn’t support service workers
  • The service worker registration tasks that we put in the AppModule class a while ago only register it when the app is running in a production environment
  • The required static files generated by the Angular CLI using the angular.json configuration file that we modified earlier on will only be available in production environments

However, we can easily work around these limitations by compiling our Angular app for production and then running the generated files with a separate, dedicated HTTP server.
