    @ViewChild('whatsNew') private readonly modal?: NgxWhatsNewComponent;

    /** Options for the modal */
    public options: DialogOptions = {
      enableKeyboardNavigation: true,
      clickableNavigationDots: true,
      disableClose: false,
      customStyle: {
        width: '500px',
        backgroundColor: '#fff',
        borderSize: '1px',
        textColor: '#222',
        borderRadius: '10px',
        boxShadow: '0px 0px 10px 5px #999',
      },
    };

    /** definition of all modals to show */
    modals = [
      {
        title: 'Whats new in v1.0.0',
        html: 'Lorem ipsum dolor sit amet, consectetur adipiscing el aspect et just.<br /><a href="http://google.com">test</a> ',
        image: {
          height: 500,
          src: 'https://picsum.photos/500',
          altText:
            'In v1.0.0, lorem ipsum dolor sit amet.',
        },
        button: {
          text: 'Okay',
          textColor: '#fff',
          bgColor: '#333',
          position: 'center',
        },
      },
      ...
    ];

    public openDialog(): void {
      this.modal?.open();
    }

    public onOpen(): void {
      console.log('Dialog opened');
    }

    public onClose(): void {
      console.log('Dialog closed');
    }

    public onNavigation($event: NavigationEvent) {
      console.info('Previous item:', $event.previousItem);
      console.info('Current item:', $event.currentItem);
    }

Note

Optionally, you could use @if to conditionally render the component. Like so:

app.component.html

@if (isDialogVisible) {
  <ngx-whats-new
    #whatsNew
    (opened)="onOpen()"
    (closed)="onClose()"
    (navigation)="onNavigation($event)"
    [items]="modals"
    [options]="options"
  />
}

app.component.ts

  public isDialogVisible: boolean | undefined;

  public openDialog(): void {
    isDialogVisible = true;
  }

  public onClose(): void {
    isDialogVisible = false;
  }
