How to Create Routing Module in Angular?

Step 1: Create New App

You can easily create your angular app using bellow command:

ng new my-module-app

Step 2: Create Admin Module

After creating successfully app, we need to create module using angular cli command. angular provide command to create module with routing in angular application. so let’s run bellow command to create admin module:

ng g module admin --routing

run successfully command, it will create files as like bellow path:

src/app/admin/admin.module.ts
src/app/admin/admin-routing.module.ts

Step 3: Create Component For Module

Now we will add new component to our admin module using bellow command, so let’s create home, user and post component for admin module:

ng g component admin/home
ng g component admin/user
ng g component admin/post

run successfully command, it will create folder with files as like bellow path:

src/app/admin/home/*
src/app/admin/user/*
src/app/admin/post/*

There is html file to all three component. so you can simple update that file with your content to checking demo if you want.

Step 4: Add Route for Component

In this step, we will simply add route with created component. so we have to update our admin-routing module file as like bellow code:

src/app/admin/admin-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { UserComponent } from './user/user.component';
import { PostComponent } from './post/post.component';
const routes: Routes = [
  {path : '', component : HomeComponent},
  {path : 'user', component : UserComponent},
  {path : 'post', component : PostComponent}
];
@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class AdminRoutingModule { }

Step 5: Update Component HTML File

here, we have to update our app component html file, we need to add links of all route with router-outlet, so let’s update it as like bellow:

I used bootstrap class on this file. so if you want to add than then follow this link too: Install Boorstrap 4 to Angular 9.

src/app/app.component.html

<div >
  <nav >
    <a  href="#">Admin Panel</a>
    <div  id="navbarSupportedContent">
      <ul >
        <li >
          <a  href="#home" routerLink="/">Home <span >(current)</span></a>
        </li>
        <li >
          <a  href="#user" routerLink="/user">User</a>
        </li>
        <li >
          <a  href="#post" routerLink="/post">Post</a>
        </li>
      </ul>
    </div>
  </nav>
</div>
<div >
    <router-outlet></router-outlet>
</div>

Step 6: Import Module to module.ts file

In last step, we will simply import our module to module.ts file, so, let’s update that file as like bellow:

src/app/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 { AdminModule } from './admin/admin.module';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    AdminModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Now we are ready to run our example, you can run by following command:

ng serve

You will have layout like as bellow.

I hope it can help you…
