Angular Heroes Tutorial part 1 display nothing

Question

I follow the Heroes Tutorial of Angular to learn it. However, after I create the project, generate the component, modify the HTML, nothing displays on the page, not as expected. Can someone solve it? Thanks a lot!

Here are my codes

heros.component.ts

import { Component, OnInit } from '@angular/core';
@Component({
  selector: 'app-heros',
  templateUrl: './heros.component.html',
  styleUrls: ['./heros.component.css']
})
export class HerosComponent implements OnInit {
  hero="WindStorm"
  constructor() { }

  ngOnInit(): void {
  }

}

heros.component.html

<h2>{{hero}}</h2>

app.component.html

<h1>
  {{title}}
</h1>
<app-heros></app-heros>

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HerosComponent } from './heros/heros.component';

@NgModule({
  declarations: [
    AppComponent,
    HerosComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app-routing.modules.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {HerosComponent} from './heros/heros.component'


const routes: Routes = [{path:'', component:HerosComponent}];

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

I think the issue is the way you are routing. Your app.component.html should look something like this

<h1>
  {{title}}
</h1>
<router-outlet></router-outlet>

The following line basically replaces the router-outlet tag with an instance of the Heroes Component:

const routes: Routes = [{path:'', component:HerosComponent}];
