Programmatic API

To create FaIconComponent dynamically using ComponentFactoryResolver:

@Component({
  selector: 'fa-host',
  template: '<ng-container #host></ng-container>'
})
class HostComponent {
  @ViewChild('host', {static: true, read: ViewContainerRef}) container: ViewContainerRef;

  constructor(private cfr: ComponentFactoryResolver) {
  }

  createIcon() {
    const factory = this.cfr.resolveComponentFactory(FaIconComponent);
    const componentRef = this.container.createComponent(factory);
    componentRef.instance.icon = faUser;
    // Note that FaIconComponent.render() should be called to update the
    // rendered SVG after setting/updating component inputs.
    componentRef.instance.render();
  }
}

To update FaIconComponent programmatically:

@Component({
  selector: 'fa-host',
  template: '<fa-icon [icon]="faUser" (click)="spinIcon()"></fa-icon>'
})
class HostComponent {
  faUser = faUser;

  @ViewChild(FaIconComponent, {static: true}) iconComponent: FaIconComponent;

  spinIcon() {
    this.iconComponent.spin = true;
    // Note that FaIconComponent.render() should be called to update the
    // rendered SVG after setting/updating component inputs.
    this.iconComponent.render();
  }
}
