type LoadChildrenCallback = () => Type<any> | NgModuleFactory<any> | Observable<Type<any>> | Promise<NgModuleFactory<any> | Type<any> | any>;
      
      type LoadChildrenCallback = () => Type<any> | NgModuleFactory<any> | Observable<Type<any>> | Promise<NgModuleFactory<any> | Type<any> | any>;

说明

Often this function will be implemented using an ES dynamic import() expression. For example:

[{ path: 'lazy', loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule), }];
      
      [{
  path: 'lazy',
  loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule),
}];

This function must match the form above: an arrow function of the form () => import('...').then(mod => mod.MODULE).
