How to access _factories property from ComponentFactoryResolver in Angular9 which was available in Angular7?

问题

I used ComponentFactoryResolver to access all the entry component factories and then add routes of those components dynamically in Angular 7.

constructor(private componentFactoryResolver: ComponentFactoryResolver) {
}

var factories = this.componentFactoryResolver['_factories']

let route: Route = {
                path: MyPath,
                component: factories[0].factory[1].componentType
            };

this.router.resetConfig(config);

I updated my project to Angular 9 and now _factories are not available in ComponentFactoryResolver.

var factories = this.componentFactoryResolver['_factories']

It returns undefined in Angular 9. It will be great help if someone can suggest some way to access all the entry component list on the go. The problem is that I have don't any information available about the entry components from which I may recompile the components through Compiler and add their routes.

回答1:

I think a simpler approach might be to import the component and use it directly in place of factories[0].factory[1].componentType. Example:

import { MyComponent } from '@app/my.component';

constructor(private componentFactoryResolver: ComponentFactoryResolver) {
}

let route: Route = {
                path: MyPath,
                component: MyComponent
            };

this.router.resetConfig(config);
