Overview

This sample demonstrates a cross-platform application suite involving an Angular SPA (TodoListSPA) calling an ASP.NET Core web API (TodoListAPI) secured with Azure Active Directory (Azure AD) using the Microsoft Authentication Library for Angular (Preview) (MSAL Angular).

Scenario

TodoListSPA use MSAL-Angular to sign-in a user.
The app then obtains an access token from Azure AD for the signed-in user.
The access token is then used to authorize the call to the TodoListAPI.
TodoListAPI uses MSAL.NET and Microsoft.Identity.Web to protect its endpoint and accept authorized calls.

VS Code for running and debugging this cross-platform application.
VS Code Azure Tools Extension extension is recommended for interacting with Azure through VS Code interface.
An Azure Active Directory (Azure AD) tenant. For more information on how to get an Azure AD tenant, see How to get an Azure AD tenant.

Setup

Using a command line interface such as VS Code integrated terminal, follow the steps below:

Step 1. Clone or download this repository

git clone https://github.com/Azure-Samples/ms-identity-javascript-angular-spa-aspnetcore-webapi.git

⚠️ Given that the name of the sample is quite long, and so are the names of the referenced NuGet packages, you might want to clone it in a folder close to the root of your hard drive, to avoid file size limitations on Windows.

Step 2. Install .NET Core API dependencies

    cd TodoListAPI
    dotnet restore

Step 3. Trust development certificates

    dotnet dev-certs https --clean
    dotnet dev-certs https --trust

Learn more about HTTPS in .NET Core.

Step 4. Install Angular SPA dependencies

    cd ../
    cd TodoListSPA
    npm install

Registration

Register the sample applications with your Azure Active Directory tenant

There are two projects in this sample. Each needs to be separately registered in your Azure AD tenant. To register these projects, you can:

either follow the steps below for manual registration,
or use PowerShell scripts that:
- automatically creates the Azure AD applications and related objects (passwords, permissions, dependencies) for you.
- modify the configuration files.

Expand this section if you want to use this automation:

On Windows, run PowerShell and navigate to the root of the cloned directory

In PowerShell run:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process -Force

Run the script to create your Azure AD application and configure the code of the sample application accordingly.
In PowerShell run:
```
cd .\AppCreationScripts\
.\Configure.ps1
```
Other ways of running the scripts are described in App Creation Scripts The scripts also provide a guide to automated application registration, configuration and removal which can help in your CI/CD scenarios.
Follow the section on "Running the sample" below.

Register the service app (TodoListAPI)

Note

This sample is not configured to be a multi-tenant sample (learn more about tenancy in Azure AD). If you would like to authorize users from other tenants to use this application, you may want to review this tutorial first.

Navigate to the Microsoft identity platform for developers App registrations page.
Select New registration.
In the Register an application page that appears, enter your application's registration information:
- In the Name section, enter a meaningful application name that will be displayed to users of the app, for example TodoListAPI.
- Under Supported account types, select Accounts in this organizational directory only.
Select Register to create the application.
In the app's registration screen, find and note the Application (client) ID. You use this value in your app's configuration file(s) later in your code.
Select Save to save your changes.
In the app's registration screen, click on the Expose an API blade to the left to open the page where you can declare the parameters to expose this app as an API for which client applications can obtain access tokens for. The first thing that we need to do is to declare the unique resource URI that the clients will be using to obtain access tokens for this API. To declare an resource URI, follow the following steps:
- Click Set next to the Application ID URI to generate a URI that is unique for this app.
- For this sample, accept the proposed Application ID URI (api://{clientId}) by selecting Save.
All APIs have to publish a minimum of one scope for the client's to obtain an access token successfully. To publish a scope, follow the following steps:
- Select Add a scope button open the Add a scope screen and Enter the values as indicated below:
  - For Scope name, use access_as_user.
  - Select Admins and users options for Who can consent?
  - For Admin consent display name type Access TodoListAPI
  - For Admin consent description type Allows the app to access TodoListAPI as the signed-in user.
  - For User consent display name type Access TodoListAPI
  - For User consent description type Allow the application to access TodoListAPI on your behalf.
  - Keep State as Enabled
  - Click on the Add scope button on the bottom to save this scope.

Configure the service app (TodoListAPI) to use your app registration

Open the project in your IDE to configure the code.

In the steps below, "ClientID" is the same as "Application ID" or "AppId".

Open the TodoListAPI\appsettings.json file.
Find the key Domain and replace the existing value with your Azure AD tenant name.
Find the key ClientId and replace the existing value with the application ID (clientId) of TodoListAPI app copied from the Azure Portal.
Find the key TenantId and replace the existing value with your Azure AD tenant ID.

Register the client app (TodoListSPA)

Navigate to the Microsoft identity platform for developers App registrations page.
Select New registration.
In the Register an application page that appears, enter your application's registration information:
- In the Name section, enter a meaningful application name that will be displayed to users of the app, for example TodoListSPA.
- Under Supported account types, select Accounts in this organizational directory only.
- In the Redirect URI (optional) section, select Single-page application in the combo-box and enter the following redirect URI: http://localhost:4200/.
Select Register to create the application.
In the app's registration screen, find and note the Application (client) ID. You use this value in your app's configuration file(s) later in your code.
In the app's registration screen, click on the API permissions blade in the left to open the page where we add access to the APIs that your application needs.
- Click the Add a permission button and then,
- Ensure that the My APIs tab is selected.
- In the list of APIs, select the API TodoListAPI.
- In the Delegated permissions section, select the access_as_user in the list. Use the search box if necessary.
- Click on the Add permissions button at the bottom.

Configure the client app (TodoListSPA) to use your app registration

Open the project in your IDE to configure the code.

In the steps below, "ClientID" is the same as "Application ID" or "AppId".

Open the TodoListSPA\src\app\auth-config.json file.
Find the key clientId and replace the existing value with the application ID (clientId) of TodoListSPA app copied from the Azure Portal.
Find the key tenantId and replace the existing value with your Azure AD tenant ID.
Find the key redirectUri and replace the existing value with the Redirect URI for TodoListSPA. (by default http://localhost:4200/).
Find the key postLogoutRedirectUri and replace the existing value with the base address of TodoListSPA (by default http://localhost:4200/.
Find the key resourceUri and replace the existing value with the base address of TodoListAPI (by default https://localhost:44351/api/todolist/).
Find the app key resourceScopes and replace the existing value with scope you created earlier api://{clientId}/access_as_user.

Run the sample

Using a command line interface such as VS Code integrated terminal, locate the application directory. Then:

    cd ../
    cd TodoListSPA
    npm start

In a separate console window, execute the following commands

    cd TodoListAPI
    dotnet run

Explore the sample

Open your browser and navigate to http://localhost:4200.
Sign-in using the button on top-right corner.
Click on the Get my tasks button to access your todo list.

About the code

Initialization

Initialize MSAL Angular client by passing the configuration parameters in auth-config.json to the MSALInstanceFactory in app.module.ts. This application is configured to be a single-tenant app on Azure AD:

export function MSALInstanceFactory(): IPublicClientApplication {
  return new PublicClientApplication({
    auth: {
      clientId: auth.credentials.clientId,
      authority: 'https://login.microsoftonline.com/' + auth.credentials.tenantId,
      redirectUri: auth.configuration.redirectUri
    },
    cache: {
      cacheLocation: BrowserCacheLocation.LocalStorage,
      storeAuthStateInCookie: isIE, // set to true for IE 11
    },
  });
}

Then, in your components, MSAL Angular client will be available as MsalService:

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private authService: MsalService) {}
}

  login() {
      this.authService.loginRedirect();
    }

Calling a web API

Set up an MSALInterceptor to keep track of the protected resources that you need access to. This will intercept HTTP calls and automatically retrieve necessary tokens, as defined in protectedResourceMap.

export function MSALInterceptorConfigFactory(): MsalInterceptorConfiguration {
  const protectedResourceMap = new Map<string, Array<string>>();
  protectedResourceMap.set(auth.resources.todoListApi.resourceUri, auth.resources.todoListApi.resourceScopes);

  return {
    interactionType: InteractionType.Redirect,
    protectedResourceMap
  };
}

CORS configuration

You need to set CORS policy to be able to call the TodoListAPI in Startup.cs. For the purpose of this sample, we are setting it to allow any domain and methods. In production, you should modify this to allow only the domains and methods you designate.

    services.AddCors(o => o.AddPolicy("default", builder =>
    {
        builder.AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader();
    }));

Deployment

Deploying web API to Azure App Services

There is one web API in this sample. To deploy it to Azure App Services, you'll need to:

create an Azure App Service
publish the projects to the App Services

Publish your files (TodoListAPI)

Sign-in to App Service using an Azure AD Account.
Open the TodoListAPI project folder.
Choose View > Terminal from the main menu.
The terminal opens in the TodoListAPI folder.
Run the following command:
```
dotnet publish --configuration Release
```
Publish folder is created under path bin/Release/<Enter_Framework_FolderName>.
Right-click on Publish folder and select Deploy to Web App.
Select Create New Web App, enter a unique name for the app.
Select Windows as the OS. Press Enter.

Disable Azure App Services default authentication (TodoListAPI)

Go to Azure Portal, and locate your project there.
- On the Settings tab, select Authentication/Authorization. Make sure App Service Authentication is Off. Select Save.
Browse your website. If you see the default web page of the project, the publication was successful.

Enable cross-origin resource sharing (CORS) (TodoListAPI)

Go to Azure Portal, and locate your project there.
- On the API tab, select CORS. Check the box Enable Access-Control-Allow-Credentials.
- Under Allowed origins, add the coordinates of your published website.

Deploying SPA to Azure Storage

There is one single-page application in this sample. To deploy it to Azure Storage, you'll need to:

create an Azure Storage blob and obtain website coordinates
build your project and upload it to Azure Storage blob
update config files with website coordinates

ℹ️ If you would like to use VS Code Azure Tools extension for deployment, watch the tutorial offered by Microsoft Docs.

Build and upload the `TodoListSPA` to an Azure Storage blob

Build your project to get a distributable files folder, where your built html, css and javascript files will be generated.

    cd TodoListSPA
    npm run build

Then follow the steps below:

⚠️ When uploading, make sure you upload the contents of your distributable files folder and not the entire folder itself.

ℹ️ If you don't have an account already, see: How to create a storage account.

Sign in to the Azure portal.
Locate your storage account and display the account overview.
Select Static website to display the configuration page for static websites.
Select Enabled to enable static website hosting for the storage account.
In the Index document name field, specify a default index page (For example: index.html).
The default index page is displayed when a user navigates to the root of your static website.
Select Save. The Azure Portal now displays your static website endpoint. Make a note of the Primary endpoint field.
In the TodoListSPA project source code, update your configuration file with the Primary endpoint field as your new Redirect URI (you will register this URI later).
Next, select Storage Explorer.
Expand the BLOB CONTAINERS node, and then select the $web container.
Choose the Upload button to upload files.
If you intend for the browser to display the contents of file, make sure that the content type of that file is set to text/html.
In the pane that appears beside the account overview page of your storage account, select Static Website. The URL of your site appears in the Primary endpoint field. In the next section, you will register this URI.

Update the Azure AD app registration for TodoListSPA

Navigate back to to the Azure portal.
In the left-hand navigation pane, select the Azure Active Directory service, and then select App registrations.
In the resulting screen, select TodoListSPA.
In the app's registration screen, select Authentication in the menu.
- In the Redirect URIs section, update the reply URLs to match the site URL of your Azure deployment. For example:
  - https://TodoListSPA.azurewebsites.net/

Update authentication configuration parameters (TodoListSPA)

In your IDE, locate the TodoListSPA project. Then, open TodoListSPA\src\app\auth-config.json.
Find the key for redirect URI and replace its value with the address of the web app you published, for example, https://TodoListSPA.azurewebsites.net.
Find the key for web API endpoint and replace its value with the address of the web API you published, for example, https://TodoListAPI.azurewebsites.net/api.
