The following code works:
/*app.module.ts*/
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { LetterRecall } from './letterRecall/letterRecall.component';
@NgModule({
imports: [BrowserModule, HttpModule],
declarations: [AppComponent, LetterRecall],
bootstrap: [AppComponent],
})
export class AppModule {}
/*app.component.ts*/
import {Component} from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: 'app/app.component.html'
})
export class AppComponent { }
/*app.component.html*/
<h3>Title</h3>
<letter-recall></letter-recall>
Following the Angular Routing Tutorial here: https://angular.io/docs/ts/latest/tutorial/toh-pt5.html
I modified my code to:
/*index.html*/
<head>
<base href="/">
/*app.module.ts*/
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { LetterRecall } from './letterRecall/letterRecall.component';
@NgModule({
imports: [BrowserModule,
HttpModule,
RouterModule.forRoot([
{ path: 'letters', component: LetterRecall }
])],
declarations: [AppComponent, LetterRecall],
bootstrap: [AppComponent],
})
export class AppModule {}
/*app.component.ts*/
import {Component} from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: 'app/app.component.html'
})
export class AppComponent { }
/*app.component.html*/
<h3>Title</h3>
<a routerLink="/letters">Letters</a>
<router-outlet></router-outlet>
At this point I get the following error:
"Unhandled Promise rejection: Template parse errors: 'router-outlet' is not a known element: 1. If 'router-outlet' is an Angular component, then verify that it is part of this module. ....."
I am using the following versions:
"@angular/common": "2.4.0",
"@angular/compiler": "2.4.0",
"@angular/core": "2.4.0",
"@angular/forms": "2.4.0",
"@angular/http": "2.4.0",
"@angular/platform-browser": "2.4.0",
"@angular/platform-browser-dynamic": "2.4.0",
"@angular/router": "3.4.0"
All of the other answers on SO indicate I need to import RouterModule but as you can see above, I am doing this as prescribed in the tutorial.
Any suggestions on where I can look for the source of this error? I started off using John Papa's First Look tutorial on PluralSight but it looks like that code is a little old now. That's when I stripped all of that out and went bare-bones through the tutorial and I get this error... I am not sure where to turn next.
The angular router directive is part of part of lib: @angular/router and it acts a placeholder which is filled up by angular state.
Here I am dividing two file separately i.e. app.module.ts and app.router.ts
Here app.router.ts
Here app.module.ts
Now you can use
<router-outlet></router-outlet>in your app.component.ts file and won't show any errorProbably I'm late here, but since I got the exaclty same issue and found an answer here.
Are you using angular-cli? https://github.com/angular/angular-cli/pull/3252/files#diff-badc0de0550cb14f40374a6074eb2a8b
In my case I just had to import my new router module in the app.component.spec.ts The js import and NgModule import.
Then restart the test server.
Like Erion said: In my case I did (added) two things in app.component.spec.ts:
