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.

Creating our first Blazor application

Throughout the book, we will create a blog engine. There won't be a lot of business logic that you'll have to learn; the app is simple to understand but will touch base on many of the technologies and areas you will be faced with when building a Blazor app.

The project will allow visitors to read blog posts and search for them. It will also have an admin site where you can write a blog post, which will be password-protected.

We will make the same app for both Blazor Server and Blazor WebAssembly, and I will show you the steps you need to do differently for each platform.

Important note

This guide will use Visual Studio 2019 from now on but other platforms have similar ways of creating projects.

Creating a Blazor Server application

To start, we will create a Blazor Server application and play around with it:

  1. Start Visual Studio 2019 and you will see the following screen:
