how to route from one component to another in angular code example

Example 1: redirect angular

import { RoleComponent } from './role/role.component';
import { AppComponent } from './app.component';
import { NgModule }             from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  { path: '', redirectTo: '/AppComponent', pathMatch: 'full' },
  { path: 'role', component: RoleComponent },

];

@NgModule({
  imports: [ RouterModule.forRoot(routes) ],
  exports: [ RouterModule ]
})
export class AppRoutingModule {
  constructor(private router: Router)
}

functionOnWhichRedirectShouldHappen(){
  router.navigate(['/role']);
}

Example 2: angular navigate using component

import {Router} from '@angular/router'; // import router from angular router

export class Component{ 				// Example component.. 
	constructor(private route:Router){} 
  
  	go(){
		this.route.navigate(['/page']); // navigate to other page
	}
}

Example 3: home page routing in angular

const routes: Routes = [
  { path: 'home_page_path', component: HomePageComponent }

];
add this in app routing file
