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.

Authenticatiwng and Authorizing Users in Blazor

All the features we have built and learned about so far are for any user who loads the app in the browser. Well, in real-world applications, that’s not always the case. In most of the scenarios you will face, some features require the app to know who is using it, and in other cases, the full app cannot be used until it knows who is using it.

In this chapter, we are going to learn about authentication and how it happens on the client side, what authentication means, and how we can implement it in Blazor WebAssembly.

We will explore the Blazor authentication library in depth, alongside most of its capabilities that enable you to build enterprise-level single-page applications. To understand everything in detail, we will build a custom authentication flow. After building the core, we will take advantage of the authentication library to restrict access to some pages to only logged-in users, show or hide partial content in the...
