To open a modal popup without a button click in Angular, leverage lifecycle hooks or events that suit your use case. For instance, use `ngOnInit` or `ngAfterViewInit` in your component to programmatically launch the modal right when the component loads or initializes. You'll need to inject the modal service (e.g., `NgbModal` from `@ng-bootstrap/ng-bootstrap` or `MatDialog` from `@angular/material`) into your component's constructor. Then, call the `open` method on the service with your modal component as an argument in the chosen lifecycle hook.
