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.

The first of these will involve the server-side aspects of our application, while the second will be performed on the client side. Both will help us discover whether we have really understood everything there is to know before proceeding to subsequent chapters.

Static file caching

Let's start with the server-side task. Do you remember the /wwwroot/test.html file we added when we wanted to check how the StaticFiles middleware works? We will use it to do a quick demonstration of how our application will internally cache static files.

The first thing we have to do is to run the application in debug mode (by clicking on the Run button or pressing the F5 key). When the app is fully loaded, press CTRL+SHIFT+J to open the Developer tools bar and navigate to the Network...
