Web Development with Blazor

By: Jimmy Engström

Overview of this book

Blazor is an essential tool if you want to build interactive web apps without JS, but it comes with its own learning curve. Web Development with Blazor will help you overcome most common challenges developers face when getting started with Blazor and teach you the best coding practices. You’ll start by learning how to leverage the power of Blazor and explore the full capabilities of both Blazor Server and Blazor WebAssembly. Then you’ll move on to the practical part, which is centred around a sample project – a blog engine. This is where you’ll apply all your newfound knowledge about creating Blazor Server and Blazor WebAssembly projects, the inner working of Razor syntax, and validating forms, as well as creating your own components. You’ll learn all the key concepts involved in web development with Blazor, which you’ll also be able to put into practice straight away. By showing you how all the components work together practically, this book will help you avoid some of the common roadblocks that novice Blazor developers face and inspire you to start experimenting with Blazor on your other projects. When you reach the end of this Blazor book, you'll have gained the confidence you need to create and deploy production-ready Blazor applications.

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 an 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...
