Login

Let’s add a login/logout link in the top-right corner.

In our AppComponent, we add a boolean property to manage the login status, and we use the authentication service to set its value:

export class AppComponent {

  logged = false;

  constructor(
    ...
  ) {
    ...
    this.services.authentication.isAuthenticated.subscribe(auth => {
      this.logged = auth.state;
    });
  }

Now, if we are not logged in yet, we display in app.component.html a link to traverse to the @@login view:

<div class="row">
  <div class="col-md-12">
    <a *ngIf="!logged" traverseTo="@@login" class="pull-right">Login</a>
  </div>
</div>

Let’s implement the logout link.

Solution

We add a second link with an output bound to the click event, which will call the logout() method of our component.

<div class="row">
  <div class="col-md-12">
    <a *ngIf="!logged" traverseTo="@@login" class="pull-right">Login</a>
    <a *ngIf="logged" (click)="logout()" class="pull-right">Logout</a>
  </div>
</div>

So let’s define the logout() method:

logout() {
  this.services.authentication.logout();
}

Now if we create private contents in Plone, they won’t show unless we are logged in.
