LoadChildrenCallback
A function that is called to resolve a collection of lazy-loaded routes.
type LoadChildrenCallback = () => Type<any> | NgModuleFactory<any> | Observable<Type<any>> | Promise<NgModuleFactory<any> | Type<any> | any>;
参见
Route#loadChildren.
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),
}];
This function must match the form above: an arrow function of the form () => import('...').then(mod => mod.MODULE).
