# Sample Blazor Webassembly project Using Cognito Hosted UI Authentication

- Create dotnet WASM project

    ```dotnet new blazorwasm -au Individual -o BlazorWasmCognitoSample```

    This should create a Blazor WASM project with Indivdual type authentication

- [Optional] Create AWS Cognito User Pool. 

    [Sample Cloudformation - cognito-stack.yml](./.cloudformation/cognito-stack.yml)

    [Deploy Script - deploy-cognito-stack.sh](./.cloudformation/deploy-cognito-stack.sh)

    If you are using an existing user pool, make sure the CallbackURLs and LogoutURLs match exactly.  A common cause of grief is the missing or additional trailing slashes.

    Also you will need to configure the Hosted UI.

- Update appsettings.json or appsettings.development.json under wwwroot.  Make sure to replace , ,  with your values.

    ```

    {

        "Cognito": {

            "Authority": "https://cognito-idp..amazonaws.com/",

            "ClientId": "",

            "RedirectUri": "https://localhost:5001/authentication/login-callback",

            "PostLogoutRedirectUri": "https://localhost:5001/authentication/logout-callback",

            "ResponseType": "code"

        }

    }

    ```

- Update Program.cs, to refer to the correct config

    ```

    builder.Services.AddOidcAuthentication(options =>

    {

        builder.Configuration.Bind("Cognito", options.ProviderOptions);

    });

    ```    

    

- Add Authorize Attribute to pages which needs to be protected

    ```

        @using Microsoft.AspNetCore.Authorization

        @page "/fetchdata"

        @attribute [Authorize]

        @inject HttpClient Http

        Weather forecast

        ...

    ```

- Run

    ```dotnet run```
