Overview of this book

Blazor is an essential tool if you want to build interactive web apps without JavaScript, but it has a learning curve. Updated with the latest code in .NET 7 and C# 11 and written by someone who adopted Blazor early, this book will help you overcome the challenges associated with being a beginner with Blazor and teach you the best coding practices. You’ll start by learning how to leverage the power of Blazor and exploring the full capabilities of both Blazor Server and Blazor WebAssembly. Then you'll move on to the practical part, centered around a sample project – a blog engine. You'll apply all your newfound knowledge about creating Blazor projects, the inner workings of Razor syntax, validating forms, and creating your own components. This new edition also looks at source generators, dives deeper into Blazor WebAssembly with ahead-of-time, and includes a dedicated new chapter demonstrating how to move components of an existing JavaScript (Angular, React) or MVC-based website to Blazor or combine the two. You’ll also see how to use Blazor (Hybrid) together with .NET MAUI to create cross-platform desktop and mobile applications. When you reach the end of this book, you'll have the confidence you need to create and deploy production-ready Blazor applications, and you'll have a big-picture view of the Blazor landscape.

Why do we need JavaScript?

Many say that Blazor is the JavaScript killer, but the truth is that Blazor needs JavaScript in order to work. Some events only get triggered in JavaScript, and if we want to use those events, we need to make interop.

I jokingly say that I have never written so much JavaScript as when I started developing with Blazor. Calm down… it’s not that bad.

I have written a couple of libraries that require JavaScript in order to work. They are called Blazm.Components and Blazm.Bluetooth.

The first one is a grid component and uses JavaScript interop to trigger C# code (JavaScript to .NET) when the window is resized to remove columns if all of them can’t fit inside the window.

When that is triggered, the C# code calls JavaScript to get the size of the columns based on the client width, something that only the web browser knows, and, based on that answer, it removes columns if needed.

The second one, Blazm.Bluetooth makes it possible to interact with...
