Best Practices

Use @defer with on viewport

@Component({
  template: `
    @defer (on viewport) {
      <heavy-chart />
    } @placeholder {
      <div>Loading...</div>
    }
  `
})
export class DashboardComponent {}

Use @defer with on interaction

@Component({
  template: `
    <button (click)="showModal = true">Open</button>
    @defer (when showModal) {
      <modal-component />
    }
  `
})
export class MyComponent {}

Use @defer with on hover

@Component({
  template: `
    @defer (on hover) {
      <tooltip />
    }
  `
})
export class TooltipWrapper {}
