Look inside

Add security, an essential ingredient in the recipe for a successful application. As a developer for BellyBox, an online grocery delivery company, your task is to secure the startup’s storefront web application using Blazor’s authentication and authorization features. You’ll keep customers’ identities secret by adding support for anonymous customers using Blazor’s JavaScript interop, then save their data to localStorage. You’ll also modify the checkout process by developing an order history that’s only visible to authenticated users. To handle anonymous and authenticated API traffic, you’ll configure named HttpClient services. By the end of the liveProject, you’ll have mastered services and components for authorizing users in Blazor, and provided a safe and secure online shopping experience for BellyBox’s customers.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

This liveProject is for .NET developers with C# experience who are looking to modernize their skills with Blazor. To begin these liveProjects you’ll need to be familiar with the following:

  • LINQ
  • Visual Studio (preferred, though Visual Studio Code and the dotnet CLI (Command Line Interface) may be used as an alternative)
  • .NET ecosystem
  • .NET SDKs (NET 6.0 and ASP.NET Core)
  • Basic HTML
  • Basic CSS selectors and values
  • Basic Git/GitHub commands and techniques

you will learn

In this liveProject, you’ll learn to add application security using Blazor’s authentication and authorization features.

  • Create a service that reads and writes data to the browser’s localStorage API using IJSRuntime to bridge JavaScript to C#
  • Use HttpClientFactor to create anonymous and authenticated HttpClient instances by using a Named HttpClient
  • Customize authentication state messages with RemoteAuthenticatorView
  • Use AuthorizeView component to simplify UI markup
  • Use the [Authorize] attribute to enforce authorization on pages that require credentials
