HamedStack / HamedStack.Angular.NoHost.Snippet

A VS Code snippet as a shortcut for rapidly generating code to create a no-host (container-less) component in Angular.

Problem

Angular does not support optional host-element officially so we should stick to annoying div which sometimes destroys our component design especially for 3rd party CSS frameworks like Bootstrap.

Solution

There is a trick to achieve a no-host component:

import {
  AfterViewInit,
  Component,
  ElementRef,
  OnInit,
  TemplateRef,
  ViewChild,
  ViewContainerRef
} from '@angular/core';

@Component({
  standalone: true, // or false
  selector: 'my-nohost-component',
  // Keep the same structure is necessary. 
  // Put any component's detail inside 'ng-template'.
  // You can use 'templateUrl' too but with the same structure.
  template: '<ng-template #nohost>HERE!</ng-template>',
})
export class MyNoHostComponent implements OnInit, AfterViewInit {
  constructor(
    private readonly element: ElementRef,
    private readonly viewContainer: ViewContainerRef
  ) {}
  
  @ViewChild('nohost', { static: true }) noHostRef: TemplateRef<{}> | undefined;

  ngOnInit(): void {
    if (this.noHostRef)
        this.viewContainer.createEmbeddedView(this.noHostRef);
  }
  ngAfterViewInit(): void {
    this.element.nativeElement.remove();
    /* Another way
      document
        .querySelectorAll(this.elem.nativeElement.tagName.toLowerCase())
        .forEach((el) => el.parentNode.removeChild(el));
    */
  }
}
