Overview of this book

Blazor WebAssembly makes it possible to run C# code on the browser instead of having to use JavaScript, and does not rely on plugins or add-ons. The only technical requirement for using Blazor WebAssembly is a browser that supports WebAssembly, which, as of today, all modern browsers do. Blazor WebAssembly by Example is a project-based guide for learning how to build single-page web applications using the Blazor WebAssembly framework. This book emphasizes the practical over the theoretical by providing detailed step-by-step instructions for each project. You'll start by building simple standalone web applications and progress to developing more advanced hosted web applications with SQL Server backends. Each project covers a different aspect of the Blazor WebAssembly ecosystem, such as Razor components, JavaScript interop, event handling, application state, and dependency injection. The book is designed in such a way that you can complete the projects in any order. By the end of this book, you will have experience building a wide variety of single-page web applications with .NET, Blazor WebAssembly, and C#.

Chapter 2: Building Your First Blazor WebAssembly Application

Razor components are the building blocks of Blazor WebAssembly applications. A Razor component is a chunk of user interface that can be shared, nested, and reused. Razor components are ordinary C# classes and can be placed anywhere in a project.

In this chapter, we will learn about Razor components. We will learn how to use them, how to apply parameters, and about their life cycle and their structure. We will learn how to use the @page directive to define routing. We will also learn how to use Razor syntax to combine C# code with HTML markup.

The Blazor WebAssembly project in this chapter will be created by using the Blazor WebAssembly App project template provided by Microsoft. After we create the project, we will examine it to further familiarize ourselves with Razor components. We will learn how to use components, how to add parameters, how to apply routing, how to use Razor syntax, and how to separate the Razor markup and code into separate files. Finally, we will configure our own custom project template that creates an empty Blazor WebAssembly project.

In this chapter, we will cover the following topics:

  • Razor components
  • Routing
  • Razor syntax
  • Using the Blazor App project template
  • Creating an empty Blazor WebAssembly project template
