Active Directory Authentication Library (ADAL) for Angular 6+ (Angular 6.X.X and Angular 7.X.X)
This is a wrapper library for Angular 6+ (Angular 6.X.X and Angular 7.X.X) modules over Microsoft ADAL (Azure Active Directory Authentication Library) - https://github.com/AzureAD/azure-activedirectory-library-for-js that helps you integrate your web app with Microsoft's AAD (Azure Active Directory) for authentication scenarios.
Working example at https://github.com/manishrasrani/ms-adal-angular6-example
For information on how to configure Azure Active Directory refer - https://docs.microsoft.com/en-us/azure/app-service/app-service-mobile-how-to-configure-active-directory-authentication
Consumption of the library
Step 1: Install the package
npm i microsoft-adal-angular6
Also add it to your dependencies section in package.json so that it is restored when you do an npm install.
Step 2: Import MsAdalModule and configure Adal options
In the root module of your application, import the MsAdalModule module.
Configure Adal options while importing the module.
In case you need to set configuration values dynamically at runtime, you can also pass a function:
This might be the case if you need to pass
redirectUri, since the Angular AOT compiler applies a special behavior when compiling @Decorators.
For a list of all available adal configuration options, refer - https://github.com/AzureAD/azure-activedirectory-library-for-js/blob/dev/lib/adal.js
Step 3: Secure individual routes
Use the AuthenticationGuard to secure indivuadual routes in your application. This ensures that users navigating to them must be authenticated with AAD to view them.
Import AuthenticationGuard and add it as a provider in your root module.
In your routing module, add it to the routes you want to secure -
const routes: Routes = [
Step 4 (Optional): Generating resource tokens
To generate resource level tokens for APIs your website may consume, specify the resources in your endpoints array while injecting adalConfig into MsAdalAngular6Module. Then to generate token, use acquireToken() of MsAdalAngular6Service-
Step 5 (Optional): Other properties and methods
Based on your application needs you could use the below supported properties and methods of adalSvc -
this.adalSvc.userInfo // Gives you the complete user object with various properties about the logged in user
this.adalSvc.LoggedInUserEmail // Gets the LoggedInUserEmail
this.adalSvc.LoggedInUserName // Gets the LoggedInUserName
With these steps your application should be up and running with ADAL.
