Blazor.Cognito

Is a library for using AWS Cognito in Blazor SPAs.

The idea behind this is to have an easy way of using AWS Cognito with Blazor (especially the client side) without relaying on javascript libraries.

About Cognito

Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0.

Auth0

Basic knowledge of Auth0 IDaaS platform is assumed, otherwise, visiting Auth0 docs is highly recommended.

Install-Package Blazor-Auth0-ClientSide -Version 2.0.0-Preview4

Usage

Note: Following example is for a server-side with require authenticated user implementation, for client-side and core-hosted example implementations please refer to the examples

appsettings.json or Secrets file (recommended)

{
	"Auth0":{
		"Domain": "[Your_Auth0_Tenant_Domain]",
		"ClientId": "[Your_Auth0_Client/Application_Id]",
		"ClientSecret": "[Your_Auth0_Client/Application_Secret]",
		"Audience": "[Your_Auth0_Audience/API_Identifier]"
	}
}

Startup.cs

// Import Blazor.Auth0
using Blazor.Auth0;
using Blazor.Auth0.Models;
// ...

public void ConfigureServices(IServiceCollection services)
{
	// Other code...

	/// This one-liner will initialize Blazor.Auth0 with all the defaults
	services.AddDefaultBlazorAuth0Authentication(Configuration.GetSection("Auth0").Get<ClientOptions>());	

	// Other code...
}

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
 {
    // Otrher code...

	app.UseHttpsRedirection();
	app.UseStaticFiles();
     
	// Add Blazor.Auth0 middleware     
	app.UseBlazorAuth0();

	// Other code...
 }

Replace App.razor content with the following code

App.razor

<Router AppAssembly="@typeof(Program).Assembly">
    <Found Context="routeData">
        <AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
            <Authorizing>
                <p>>Determining session state, please wait...</p>
            </Authorizing>
            <NotAuthorized>
                <h1>Sorry</h1>
                <p>You're not authorized to reach this page. You may need to log in as a different user.</p>
            </NotAuthorized>
        </AuthorizeRouteView>
    </Found>
    <NotFound>        
        <p>Sorry, there's nothing at this address.</p>        
    </NotFound>
</Router>
