import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core'; 
import { Routes,RouterModule } from '@angular/router';
import { HomeComponent } from '../buyer/home/home.component';
const routes: Routes = [
   {path: '',redirectTo:'buyer',pathMatch:"full"}
]
@NgModule({
  declarations:[],imports:[
    BrowserModule,RouterModule.forRoot(routes)
  ],exports:[RouterModule]
})

export class AppRoutingModule {}

BuyerRouting.ts

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

import { WelcomeComponent } from './welcome/welcome.component';
import { HomeComponent } from './home/home.component';

@NgModule({
declarations:[],imports:[
    CommonModule,RouterModule.forChild([
        { path: 'buyer',component: HomeComponent},{ path: '',redirectTo: '/welcome',pathMatch: 'prefix'},{ path: 'welcome',component: WelcomeComponent}
    ])
],exports:[RouterModule]
})

export class BuyerRoutingModule {}
