Angular MSAL

About this package

This package is created when @azure/msal wasn't ready to use. Because there are so many configuration options, this packages tries to make things easier. See the demo project for a working example using login-redirect and login-popup.

Changes

Installation

npm install angular-msal --save

Usage

This is how I use the package: I have a userService that has a function: TryToGetUser, which tries to get the current user from my backend (using the tokens ObjectId which I make sure is equal to my User.Id)

Add the MsalModule and HttpIntercepter in app.module.ts

@NgModule({
  imports: [
      MsalModule.forRoot({
         clientId: environment.clientId,
         authority: environment.authority + environment.userflow,
         consentScopes: environment.scopes,
         lang: 'en-US',
         level: environment.production ? LogLevel.Error : LogLevel.Info
      }),
    }),
  ],

providers: [UserService,
    { provide: HTTP_INTERCEPTORS, useClass: MsalInterceptor, multi: true }
  ]

@Injectable()
export class UserService {
    cachedUser: User;
    
    constructor(private authService: MsalService, private http: HttpClient) {
    }
    public tryToGetUser() {
        if (this.authService.getAccount()) {
            return this.getUser();
        }
        return of(null);
    }

    public getUser() {
        return this.http.get<User>(`User/loggedinuser`).pipe(tap(user => {
            this.cachedUser = user;
        }));
    }
}

login.component.ts

export class LoginPageComponent {
  constructor(private authService: MsalService, public userService: UserService, private router: Router) {

  loginRedirect = () => this.authService.loginRedirect();

  loginPopup = () => {
      const response = await this.msalService.loginPopup();
      if (response.idToken) {
        this.router.navigate(['/my-profile']);
      }
    }

To logout use

this.msalService.logout();
