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.

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 within a Visual Studio debug session; this approach will allow us to properly...
