Angular 10 nested routing & Child Routes example

Today, we will discuss with you how to configure nested routing using a Router Module and outlet. now we will create an application and add nested routing and navigation for our applications.

you can easily Add nested Routing & Child Routes to your angular application by using our example. we are creating a Simple Route application. so you can see our angular 10 nested routing & Child Routes example.

Create new angular app

We will create a new angular app using the following command.

ng new myapp
cd myapp

1 2	ng new myapp cd myapp

when you create your application at that time Angular CLI ask you Would you like to add Angular routing? (y/N). If you enter with y for Yes. then the angular router will be automatically configured.

Create a component in angular

Now we need to create three component such as home, about, and contact. So let’s run the following command to create components.

ng g c home

1	ng g c home

ng g c category

1	ng g c category

Create Nested Routes

Now, we will create two nested routes category-create and category-detail.

ng g c category/category-create

1	ng g c category/category-create

ng g c category/category-detail

1	ng g c category/category-detail

Update view file in angular

src/app/app.component.html
In this example, we will create a simple navigation menu using bootstrap. we need to routerLink for redirect the different routes and also add router-outlet.

<nav class="navbar navbar-expand-lg navbar-dark bg-primary">
    <a class="navbar-brand" routerLink="/">\Angular 10 Router Tutorial With Example</a>
    <div class="collapse navbar-collapse" id="navbarText">
        <ul class="navbar-nav mr-auto">
			<li class="nav-item">
				<a class="nav-link" routerLink="/">Home</a>
			</li>
			<li class="nav-item">
				<a class="nav-link" routerLink="/category">Category</a>
			</li>
			
        </ul>
    </div>
</nav>
<div class="container">
    <router-outlet></router-outlet>
</div>

<a class="navbar-brand" routerLink="/">\Angular 10 Router Tutorial With Example</a>

</li>

<a class="nav-link" routerLink="/category">Category</a>

</li>

</ul>

</div>

</nav>

<router-outlet></router-outlet>

</div>

src/app/home/home.component.html

<a class="btn btn-primary" routerLink="/category">Back</a>

1 2	<h3>Welcome To Create Category Page</h3> <a class="btn btn-primary" routerLink="/category">Back</a>

<h3>Welcome To Category Detail Page</h3>
<a class="btn btn-primary" routerLink="/category">Back</a>

Adding Routing to your Angular 10

src/app/app-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
  
import { HomeComponent } from './home/home.component';
import { CategoryComponent } from './category/category.component';
import { CategoryCreateComponent } from './category/category-create/category-create.component';
import { CategoryDetailComponent } from './category/category-detail/category-detail.component';

   

const routes: Routes = [
  {
      path: '',
      component: HomeComponent
  },
  {
      path: 'posts',
      children: [
        {
          path: '',
          component: CategoryComponent
        },
        {
            path: 'create',
            component: CategoryCreateComponent
        },
        {
            path: 'detail',
            component: CategoryDetailComponent
        }
    ]

  }

];

   

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]

})

export class AppRoutingModule { }

import { NgModule } from '@angular/core';

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

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

import { CategoryComponent } from './category/category.component';

import { CategoryCreateComponent } from './category/category-create/category-create.component';

import { CategoryDetailComponent } from './category/category-detail/category-detail.component';

const routes: Routes = [

{

path: '',

component: HomeComponent

{

path: 'posts',

children: [

{

path: '',

component: CategoryComponent

{

path: 'create',

component: CategoryCreateComponent

{

path: 'detail',

component: CategoryDetailComponent

}

]

}

];

@NgModule({

imports: [RouterModule.forRoot(routes)],

exports: [RouterModule]

})

export class AppRoutingModule { }
