Overview of this book

Blazor WebAssembly is a revolutionary technology in software development that enables you to develop web applications with a rich user interface using C# without JavaScript. It can be run natively in the browser and soon on mobile apps with .NET MAUI, making it a superweapon in the .NET developer’s toolbox. This capability has opened the doors for the JavaScript community to have a stable framework to build single page applications (SPAs) maintained by Microsoft and driven by the community. Mastering Blazor WebAssembly is a complete resource that teaches you everything you need to build client-side web applications using C# & .NET 7.0. Throughout this book, you’ll discover the anatomy of a Blazor WebAssembly project, along with the build, style, and structure of the components. You’ll implement forms to catch user input and collect data, as well as explore the topics of navigating between the pages in depth. The chapters will guide you through handling complex scenarios like RenderTrees, writing efficient unit tests, using variant security methods, and publishing the app to different providers, all in a practical manner. By the end of this book, you’ll have the skills necessary to build web apps with Blazor WebAssembly, along with the basics for a future in mobile development with .NET MAUI and Blazor.

Building a custom JWT authentication flow

This is the section that will contain all the action! We will put together everything we have learned so far about developing components and forms and calling a web API, in addition to all the parts we mentioned in the previous section, to add authentication to our BooksStore project.

For this exercise, we will use the /authentication/login POST API endpoint. This endpoint will accept an object with two properties – Username and Password. If they are valid, it will return an object containing the access token.

By default, the API has two users registered that we can use to test:

  • John Smith: He is an admin in the company. His email is [email protected] and his password is Test.123.
  • Ahmad Mozaffar: He is a customer of the BooksStore library. His email is [email protected] and his password is Test.123.

The custom flow we will build will consider the user authenticated when there is a valid...
