Conditionally Import Shared module using static method forRoot

Question

I have angular application divided into various modules on the basis of user type. Like AdminModule, CustomerModule, VendorMoudle etc. For each modules I've a separate respective shared module, having all the reusable items (components, pipes, directive etc). Like AdminSharedModule, CustomerSharedModule and VendorSharedModule.

Along with each shared modules I've various featured modules inside each user level module which imports the respective user's shared module. For example, all featured modules of AdminModule will import AdminShared module. Similarly, all featured modules of Customer will import CustomerSharedModule.

Now, I've a situation that there are some featured modules that belong to more than one user's module. Suppose, I've a featured module called CommonFeatureModule. Now, I can create this module anywhere in the application & can call it lazily through routing in any of the module.

Now, here is the problem. As I explained, inside each featured module, I've imported the related User's Shared module. But for CommonFeatureModule I've to conditionally import shared modules. Like if the CommonFeatureModule is loaded through AdminModule then the CommonFeatureModule should import AdminSharedModule. But if the CommonFeatureModule is loaded in CustomerModule then the CommonFeatureModule should import CustomerSharedModule.

I've tried creating a module called SharedModule & inside this module I've used the static method forRoot to conditionally load the respective user's shared module. But this solution didn't work. Her is the code for my SharedModule:

@NgModule({
    declarations: [SharedComponent],
    imports: [],
    exports: []
})
export class SharedComponent{
    static forRoot(user: UserService): ModuleWithProviders<SharedModule> {
        const data = {
            ngModule: SharedModule,
            imports: [
                user.isAdminUser() ? AdminSharedModule : CustomerSharedModule
            ],
            exports: [
                user.isAdminUser ? AdminSharedModule : CustomerSharedModule
            ]
        };

        return data;
    }
}
