What Is Blazor AuthorizeView and How to Use it?

AuthorizeView is a component in Blazor that allows developers to control the rendering of UI elements based on the user's authorization status. It provides a way to conditionally display content depending on whether a user is authenticated and authorized to access certain parts of an application.

There are multiple benefits of using AuthorizeView for your Blazor applications, some being:

• Security: Makes sensitive information and functionalities accessible to authorized users only.
• User Experience: Enhances the user experience by providing relevant content based on the user's authentication and authorization status.
• Maintainability: Centralizes authorization logic, making it easier to maintain and update security policies.

For example, the below code will yield different result based on whether the current user is authorized or not:

<AuthorizeView>
    <Authorized>
        <p>Welcome, authenticated user!</p>
    </Authorized>
    <NotAuthorized>
        <p>You are not authorized to view this content.</p>
    </NotAuthorized>
</AuthorizeView>

These are the most frequent scenarios where AuthorizeView will be helpful in your Blazor projects.
