Usage

Import NgAuthentication to your AppModule

@NgModule({

    AppComponent
  ],
  imports: [
    BrowserModule,
    NgAuthenticationModule.forRoot({
      authProvider: environment.authProvider,
      loginUri: 'signInWithLink'
    })
  ],
  providers: [],
  bootstrap: [AppComponent]
})

Directives

1. isAuthenticated

1.1. Display content in case user is authenticated

<ng-template isAuthenticated>
  <h1>Welcome user!</h1>
</ng-template>

Or

<h1 *isAuthenticated >Welcome user!</h1>

1.2. Check if user is authenticated or not and then display content accordingly

<ng-template isAuthenticated>
  <h1 * >Welcome user!</h1> <!-- This content will be displayed if user is authenticated -->
  <button * class="btn">Please sign in!</button> <!-- This content will be displayed if not -->
</ng-template>

1.3. Display content in case user is unauthenticated

<ng-template isAuthenticated>
  <ng-template></ng-template> <!-- Trick: Define empty content for the right condition -->
  <button * class="btn">Please sign in!</button>
</ng-template>

2. isCurrentUser

2.1. Display content in case logger is current user

<ng-template [isCurrentUser]="'vix'">
  <h1>It me ¯\_(ツ)_/¯</h1>
</ng-template>

Or

<h1 *isCurrentUser="'vix" >It me ¯\_(ツ)_/¯</h1>

2.2. Check if logger is current user or not and then display content accordingly

<ng-template [isCurrentUser]="'vix'">
  <h1 * >It me ¯\_(ツ)_/¯</h1> <!-- This content will be displayed if logger is current user -->
  <button * class="btn">Who are you?</button> <!-- This content will be displayed if not -->
</ng-template>

2.3. Display content in case current user is not logged in

<ng-template [isCurrentUser]="'vix'">
  <ng-template></ng-template> <!-- Trick: Define empty content for the right condition -->
  <button * class="btn">Who are you?</button>
</ng-template>

3. userRole

Check & display based on user role (the same concepts with ngSwitchCase)

<ng-template userRole>
  <ng-template [userRoleIs]="'admin'">
    <button class="btn">Remove</button>
  </ng-template>
</ng-template>

Or

<ng-template userRole>
  <button *userRoleIs="'admin'" class="btn">Remove</button>
</ng-template>

Services

Inject NgAuthenticationService into AppComponent (in case you want to use some method of this service)

export class AppComponent {

  constructor(
    @Inject(NgAuthenticationService) private auth: NgAuthenticationService
  ) {}

}
