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.

Using the command line

With .NET 5, you get a super powerful tool called dotnet.exe. Developers that have used .NET Core before will already be familiar with the tool, but with .NET 5, it is no longer exclusively for .NET Core developers.

It can do a lot of the things Visual Studio can do, for example, creating projects, adding and creating NuGet packages, and much more. In the next example, we will create a Blazor Server project.

Creating a Blazor Server project using the command line

The following steps are just for demonstrating the power of using the command line. We will not use this project later in the book, so if you don't want to try it, go ahead and skip this section. To create a new Blazor Server project, you can use this command:

dotnet new blazorserver -o BlazorServerSideApp

Here, dotnet is the command, and to create a new project, you use the new parameter.

blazorserver is the name of the template and -o is the output folder (in this case, the project...
