Generating a TemplateRef within an Angular 10 service

Question

Generating a TemplateRef within an Angular 10 service

We are using ngZorro in our Angular 10 project. Currently, we want to implement a functionality where clicking on a product from a list will open its form in a drawer ().

To achieve this, we are utilizing NzDrawerService to create the drawer. However, we are facing challenges in setting up the footer (nzFooter).

For instance, let's consider a ProductFormComponent. In our ProductService.ts file, we have the following code snippet:

openForm(){
  const drawerRef = this.drawerService.create({
      nzTitle: 'My Title',
      nzContent: ProductFormComponent
  });
  drawerRef.open()
}

We also need to add buttons for save and cancel in the footer by specifying

nzFooter?: string | TemplateRef<{}>

. The issue arises when trying to incorporate a TemplateRef within a service function call rather than a component.

Answer №1

If I were to insert a single template into a service, one approach would be to use a "dummy" component specifically for this purpose.

To set a templateRef in the drawer service, you can add a function like this:

private template: TemplateRef<any>;
setTemplate(template: TemplateRef<any>) {
  this.template = template;
}

The dummy component might look something like this:

@Component({
  selector: "template-injector",
  template: `
    <ng-template #myTemplate>
      <h1>Best Template!</h1>
    </ng-template>
  `,
  styleUrls: []
})
export class TemplateInjectorComponent implements AfterViewInit {
  constructor(private derviceService: DrawerService) {}

  @ViewChild("myTemplate") template: TemplateRef<any>;

  ngAfterViewInit(): void {
    this.derviceService.setTemplate(this.template);
  }
}

Lastly, locate the main component in your application and load the TemplateInjectorComponent. Since the template is just <ng-template>, nothing will be displayed (consider placing it at the end of your layout component).

Alternatively, instead of creating a new component, you could incorporate it into the main app component.
