Blazor WebAssembly by Example

By: Toi B. Wright

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#.

Summary

You should now be able to create a hosted Blazor WebAssembly app that uses the ASP.NET Web API to update data in a SQL Server database.

In this chapter, we introduced hosted Blazor WebAssembly apps, the HttpClient service, and the JSON helper methods used to read, create, and update data. We also demonstrated how to delete data using the HttpClient.DeleteAsync method.

After that, we used Microsoft's Blazor WebAssembly App project template to create a hosted Blazor WebAssembly app. We examined the demo project and then deleted it from the multi-project solution. We added both a TaskItem class and a TaskItem API controller. Next, we configured SQL Server by updating the connection string to the database and using Entity Framework migrations. Finally, we used the HttpClient service to read the list of tasks, update a task, delete a task, and add new tasks.

We can apply our new skills to create a hosted Blazor WebAssembly app that is part of a multi-project solution...
