Answer 1

There are two ways. 1. if you want to implement app.module.ts file then:

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

const appRoutes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'user', component: UserComponent },
  { path: 'server', component: ServerComponent }
];

@NgModule({
  imports: [
    RouterModule.forRoot(appRoutes)
  ]
})
export class AppModule { }

2. if you want to implement app-routing.module.ts (Separated Routing Module) file then:

//app-routing.module.ts
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

const appRoutes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'users', component: UsersComponent },
  { path: 'servers', component: ServersComponent }
];

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

//................................................................

//app.module.ts
import { AppRoutingModule } from './app-routing.module';

@NgModule({
  imports: [
    AppRoutingModule
  ]
})
export class AppModule { }

Answer 2

Assuming you are using Angular 6 with angular-cli and you have created a separate routing module which is responsible for routing activities - configure your routes in Routes array.Make sure that you are declaring RouterModule in exports array. Code would look like this:

@NgModule({
      imports: [
      RouterModule,
      RouterModule.forRoot(appRoutes)
     // other imports here
     ],
     exports: [RouterModule]
})
export class AppRoutingModule { }

Answer 3

It works for me, when i add following code in app.module.ts

@NgModule({
...,
   imports: [
     AppRoutingModule
    ],
...
})

Answer 4

Try this:

Import RouterModule into your app.module.ts

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

Add RouterModule into your imports []

like this:

 imports: [    RouterModule,  ]

Answer 5

In your app.module.ts file

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

const appRoutes: Routes = [
{
    path: '',
    redirectTo: '/dashboard',
    pathMatch: 'full',
    component: DashboardComponent
},  
{
    path: 'dashboard',
    component: DashboardComponent
}
];

@NgModule({
imports: [
    BrowserModule,
    RouterModule.forRoot(appRoutes),
    FormsModule               
],
declarations: [
    AppComponent,  
    DashboardComponent      
],
bootstrap: [AppComponent]
})
export class AppModule {

}

Add this code. Happy Coding.

Here is the Quick and Simple Solution if anyone is getting the error:

"'router-outlet' is not a known element" in angular project,

Then,

Just go to the "app.module.ts" file & add the following Line:

import { AppRoutingModule } from './app-routing.module';

And also 'AppRoutingModule' in imports.
