@ngx-ssr/platform

Install package

npm i @ngx-ssr/platform

To determine the platform, use the tokens IS_SERVER_PLATFORM and IS_BROWSER_PLATFORM

@Directive({
  selector: '[some-directive]',
})
export class SomeDirective {
  constructor(
    @Inject(IS_SERVER_PLATFORM) isServer: boolean,
  ) {
    if (isServer) {
      viewContainer.createEmbeddedView(templateRef);
    }
  }
}

Use the ifIsServer and  ifIsBrowser structural directives in your template for rendering contents depending on the platform:

@Component({
  selector: 'ram-root',
  template: '<some-сomp *ifIsServer"></some-сomp>',
  styleUrls: ['./app.component.less'],
})
export class AppComponent {
}
