问题
I have the following code to load a module dynamically:
export class DynamicQuestionComponent {
constructor(
private componentFactoryResolver: ComponentFactoryResolver,
private viewContainerRef: ViewContainerRef
) {}
@Input() form: FormBase;
@Input() formgroup: FormGroup;
@ViewChild('content', { read: ViewContainerRef, static: true }) content: ViewContainerRef;
@Input() set question(qvalue){
if (qvalue){
this.content.clear();
var compath = `./${qvalue.qType}-question.component`;
var testpath = './proto-question.component';
import('./proto-question.component').then( dyncomp => {
const component = this.viewContainerRef.createComponent(this.componentFactoryResolver.resolveComponentFactory(dyncomp.ProtoQuestionComponent));
(<any>component).instance.form = this.form;
(<any>component).instance.question = qvalue;
(<any>component).instance.formgroup = this.formgroup;
this.content.insert(component.hostView);
component.injector.get(ChangeDetectorRef).markForCheck();
})
}
}
}
Currently, this is the only way it works, if I hard code the component path inside of the import function. I want to be able to pass a variable into the import function, but each time I switch to the variable, I get the dreaded cannot find module error:
ERROR Error: Uncaught (in promise): Error: Cannot find module './proto-question.component'
As you can see, I even tested a variable that is exactly the same as the hardcoded version and that fails as well.
I feel like there must be a setting to make this work properly.
I"m using:
Angular 9.1.9
Angular CLI 9.1.4
Assuming I can get past the dynamic variable issue, then I need to figure out how to get pass in the dynamic component into the resolveComponentFactory call.

Unfortunately loading a dynamic module by variable is not possible. I have similar issue and i can't find a solution. Dynamically import modules with dynamic routes
