Vue js过滤问题？

Question

我需要使新用户过滤列表类别。而且我总是失败。你能帮助我吗？以前非常感谢。！！

代码：

import { 
    Injectable, Compiler, Injector, Type, 
    ViewContainerRef, ComponentFactoryResolver,
    NgModuleFactory, Inject 
} from '@angular/core';

@Injectable()
export class LazyLoaderService {

  constructor(private injector: Injector,
    private compiler: Compiler,
    @Inject(LAZY_WIDGETS) private lazyWidgets: 
       { [key: string]: () => Promise<NgModuleFactory<any> | Type<any>> }) { }


  async load(name: string, container: ViewContainerRef) {
    const ngModuleOrNgModuleFactory = await this.lazyWidgets[name]();

    let moduleFactory;

    if (ngModuleOrNgModuleFactory instanceof NgModuleFactory) {
      // aot mode
      moduleFactory = ngModuleOrNgModuleFactory;
    } else {
      // jit mode
      moduleFactory = await this.compiler.compileModuleAsync(ngModuleOrNgModuleFactory);
    }

    const entryComponent = (<any>moduleFactory.moduleType).entry;
    const moduleRef = moduleFactory.create(this.injector);

    const compFactory = moduleRef.componentFactoryResolver.resolveComponentFactory(entryComponent);

    const comp = container.createComponent(compFactory);
  }   
}
