Type 'string' is not assignable to type 'LoadChildrenCallback

Question

I am using Angular 13 and created a myapp.mainrouting.js file and trying to declare loadChildren as below:

import {CustomerAppHomeComponent} from "../Home/CustomerApp.HomeComponent";
import {Routes} from "@angular/router";    

export const MainRoutes: Routes  = [
  { path: 'Home', component: CustomerAppHomeComponent },
  { path: 'Supplier', loadChildren: '../Supplier/CustomerApp.SupplierModule#CustomerAppSupplierModule' },
  { path: '', component: CustomerAppHomeComponent },
]

However, I am getting below error:

error TS2322: Type 'string' is not assignable to type 'LoadChildrenCallback | undefined'.

8   { path: 'Supplier', loadChildren: '../Supplier/CustomerApp.SupplierModule#CustomerAppSupplierModule' },
                        ~~~~~~~~~~~~

  node_modules/@angular/router/router.d.ts:1998:5
    1998     loadChildren?: LoadChildren;
             ~~~~~~~~~~~~
    The expected type comes from property 'loadChildren' which is declared here on type 'Route'

Answer 1

For dynamic imports you'll need to update this

{ path: 'Supplier', loadChildren: '../Supplier/CustomerApp.SupplierModule#CustomerAppSupplierModule' },

To this:

{ 
   path: 'Supplier',
   loadChildren: () => import('../Supplier/CustomerApp.SupplierModule').then(x => x.CustomerAppSupplierModule)
},

Also double check that in your tsconfig.json you have this line "module": "esnext"

{
...
"compilerOptions": {
    ...
    "module": "esnext"
    ...
    }
}
