Angular 2 How to create role for Admin side and Client side?

Question

I want to create Admin role and user role for separate routes

app.routing.ts

import {RouterModule, Routes} from '@angular/router';
import { NgModule } from '@angular/core';

const appRoutes: Routes = [
  {
    path:'',
    loadChildren: './client/client.route.module#ClientRouteModule'
  },
  {
    path:'admin',
    loadChildren: './admin/admin.route.module#AdminRouteModule'
  }
];
@NgModule({
  declarations: [],
  imports: [RouterModule.forRoot(appRoutes)],
  providers: [],
  bootstrap: [],
  exports: [RouterModule]
})
export class AppRoutingModule { }

in this code how to create and add role for user and admin. something else add in child routes? I want to create role for / for open frontend login and /admin for admin login still i have a problem for login without role. once login in frontend then admin automatic logged in because role is not added in local storage. I want to define role and store in local storage

Thank you
