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.

Chapter 7: Creating an API

Blazor WebAssembly needs to be able to retrieve data and also change our data. For that to work, we need to have an API with which we can access the database. In this chapter, we will create a Web API.

When we are using Blazor Server, the API will be secured together with the page (if we add an Authorize attribute), so we get that for free. But with WebAssembly, everything will be executed in the browser, so we need something that WebAssembly can communicate with to update the database on the server.

To do this, we will cover need to cover three topics. In this chapter, we will cover the first two:

  • Creating the service
  • Creating the client

The third topic is Calling the API, but we won't cover that part in this chapter; instead, we will come back to it in Chapter 9, Sharing Code and Resources.
