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.

Building an admin interface

Now it's time to build a simple admin interface for our blog.

We need to be able to do the following:

  • List categories
  • Edit categories
  • List tags
  • Edit tags
  • List blog posts
  • Edit blog posts

If we look at the preceding list, we might notice that some of the things seem similar – perhaps we can build components for those. Categories and tags are very similar; they have names, and the name is the only thing we should be able to edit.

Let's make a component for that. The component is going to be responsible for listing, adding, deleting, and updating the object.

Since the object we are working with is either Category or Tag, we need to be able to call different APIs depending on the object, so our component needs to be generic:

  1. In the MyBlogServerSide project, right-click on the Components folder and select Add | Razor component, then name the component ItemList.razor.
  2. Open the newly created...
