An example-driven guide to building reusable UI components and web frontends—all with Blazor, C#, and .NET.

In Blazor in Action, you will learn about:

• Blazor + WebAssembly
• Picking the right hosting model
• Building reusable UI components
• Building forms with validation
• Integrating with JavaScript libraries
• Securing your application
• Testing your applications

Blazor in Action is a practical guide to building stunning UIs and client-side applications using C# and .NET. You’ll use the Blazor frontend framework to create a fun and exciting web application for plotting hiking routes. As you build up your new application, you’ll master the key features of Blazor, such as routing, forms and validation, and dynamic and reusable components. By the time you’re done, you’ll be ready to develop beautiful sites and apps that seamlessly execute your C# code natively in the browser.

The book is written to the most recent stable build of Blazor and seamlessly integrates fresh features from .NET 6.

Create rich web frontends without relying on JavaScript. Microsoft’s Blazor framework uses WebAssembly to extend the ultra-popular ASP.NET platform. In Blazor, you can build interactive web components that run natively in the browser without plug-ins or transpilers. And because it’s C# end-to-end, it’s easy to share code between the server and your web UI.

Blazor in Action teaches you to create full-stack ASP.NET applications end-to-end in C#. You’ll start by learning to build Blazor web components, working through core topics like routing and forms. As you go, you’ll implement a hiking route web application that includes reusable code, integration with JavaScript libraries, and role-based security. To make sure your app is production ready, this practical book also covers state management, data persistence, and testing.
