Define different routes inside routing.module

Question

I want to define different routes according to a flag. This is part of

app-routing.module.ts

 import { Token } from "...";  //  InjectionToken

 let routes: Routes;
 @NgModule({
   imports: [RouterModule.forRoot(routes)],
   exports: [RouterModule]
})
export class AppRoutingModule {
  constructor(@Inject(Token) private token) {
    if (this.token) {
      routes = [...]
    }
    else {
       routes =[...]
    }
  }

Unfortunately, the above does not work. Any idea how to achieve what I want?

Answer 1

Try to set the router config as below:

import { Token } from "...";  //  InjectionToken

 let routes: Routes;
 @NgModule({
   imports: [RouterModule.forRoot(routes)],
   exports: [RouterModule]
})
export class AppRoutingModule {
  constructor(@Inject(Token) private token,
   router: Router) {
    let config = router.config;
    if (this.token) {
      routes = [...]
    }
    else {
       routes =[...]
    }
    config = routes;
    router.resetConfig(config);
  }
}
