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 8: Authentication and Authorization

In this chapter, we will learn how to add authentication and authorization to our blog, because we don't want just anyone to be able to create or edit blog posts.

Covering authentication and authorization fully would itself take a whole book, so we will keep things simple here. The goal of this chapter is to get the built-in authentication and authorization functionalities working, building on the already existing functionality that's built in to ASP.NET. That means that there is not a lot of Blazor magic involved here; there are a lot of resources that already exist that we can take advantage of.

Almost every system today has some way to log in, whether it is an admin interface (like ours) or a member login portal. There are many different login providers, such as Google, Twitter, and Microsoft. We can use all of these providers since we will just be building on already existing architecture.
