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.

Learning Razor syntax

One of the things I like about the Razor syntax is that it is easy to mix code and HTML tags. This section will be a lot of theory to help us get to know the Razor syntax.

To transition from HTML to code (C#), we use the @ symbol. There are a couple of ways we can add code to our file:

  • Razor code blocks
  • Implicit Razor expressions
  • Explicit Razor expressions
  • Expression encoding
  • Directives

Razor code blocks

We have already seen some code blocks. A code block looks like this:

@code {
    //your code here
}

If we wish, we can skip the code keyword, like so:

@{
    //your code here
}

Inside those curly braces, we can mix HTML and code like this:

@{
    void RenderName(string name)
    {
        <p>Name: <strong>@name</strong></p>
    }
