Template for Blazor ASP.NET 6 Core Server Side authentication from any database in a multi-language project. Version 1.1

Objectives:

  • Being DB agnostic
  • Support multi language
  • Support page reload

For multi-language management install Visual Studio Tool ResXManager

https://marketplace.visualstudio.com/items?itemName=TomEnglert.ResXManager

Create a folder named Resources/Pages

Add resource file with exact same name as pages, for exemple Index.resx

Open in menu Tools/ResX Manager, add languages and create key/values pair

Look at comments in Program.cs

Look at IDBAbstraction and change it with your own code for authentication.

Display language mecanism is handle with a cookie. Because server side blazor app are Single Page App you can't change the cookie. The only way to change a cookie it is to do a page refresh. This is done in the AuthController.cs. But this mean you have to save the user id somewhere. I choose to save it in the browser's session storage. Also a great place to keep some other context.

When importing in a new project don't forget to add <CascadingAuthenticationState> in App.razor

Protected pages must use the following scheme

@page "/path"
@inherits LoadUserContext

<AuthorizeView>
    <Authorized>
        <h1>@i_localizer["Hello"], @(auth.m_login) - @context.User.Identity.Name</h1>
    </Authorized>
    <NotAuthorized>
        <Login />
    </NotAuthorized>
</AuthorizeView>

TODO: Introduce JWT Bearer token and link it with Blazor user session for API calls and SignalR protection.
