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.
Like Erion said: In my case I did (added) two things in app.component.spec.ts:
import { RouterTestingModule } from '#angular/router/testing';
...
TestBed.configureTestingModule({
imports: [ RouterTestingModule ],
declarations: [
AppComponent
],
}).compileComponents();
Probably 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.
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
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { MainComponent } from './components/main/main.component';
import { AppComponent } from './app.component';
const appRoutes: Routes = [
{ path: 'main', component: MainComponent },
{ path: '', redirectTo: '/main', pathMatch: 'full' }
];
#NgModule({
imports: [
RouterModule.forRoot(appRoutes)
],
exports: [
RouterModule
]
})
export class AppRouter { }
Here app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule } from '#angular/core';
import { AppRouter } from './app.router';
import { AppComponent } from './app.component';
import { MainComponent } from './components/main/main.component';
#NgModule({
declarations: [
AppComponent,
MainComponent
],
imports: [
BrowserModule,
AppRouter
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Now you can use <router-outlet></router-outlet> in your app.component.ts file and won't show any error

question 2:using angular in asp.net core project obligate me to use component instead of partials. is there a way to use partials with angular? i dont want to get all data from services or do i have to?
I have separated routing for modules.
This is my app.module.ts
import { NgModule, Component } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { RouterModule } from '#angular/router';
import { AppComponent } from "./app.component";
import appRoutes from "./app.routing";
import { HomeComponent } from "./app.routing";
#NgModule({
imports: [ BrowserModule, appRoutes ],
declarations: [ AppComponent, HomeComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule {
}
This is my app.routing.ts
import { RouterModule } from '#angular/router';
import { AppComponent } from "./app.component";
import { Component } from "#angular/core";
#Component({
template : `I am from home`
})
export class HomeComponent {}
const routes = [
{
path : "",
component : HomeComponent
},
{
path : "contact",
loadChildren : "app/contact/contact.module"
}
];
export default RouterModule.forRoot(routes);
This is my contact.module.ts
import { NgModule } from "#angular/core";
import { CommonModule } from "#angular/common";
import { RouterModule } from "#angular/router";
import { ContactComponent } from "./contact.component";
const routes = [
{path : "contact", component : ContactComponent}
];
#NgModule({
imports: [ CommonModule, RouterModule.forChild(routes) ],
declarations: [ ContactComponent ],
})
export default class ContactModule {
}
HomeComponent link is working fine. But If I contact route no contents are displayed in browsers
I cannot find what the issue is. Any help is greatly appreciated.
Thanks in advance.
You must specify the name of the module you're trying to load:
loadChildren : "app/contact/contact.module#ContactModule"
I have a new CLI based Angular applicaiton that I am creating. I have followed the instructions on the ng-bootstrap site.
Installed Bootstrap: npm install bootstrap#4.0.0-alpha.6
Installed ng-bootstratp: npm install --save #ng-bootstrap/ng-bootstrap
Made sure my angular version was up to date "4.1.1"
Setup the app.module.ts correctly (I think)

import { FileListComponent } from './file-list/file-list.component';
import { NavbarComponent } from './navbar/navbar.component';
import { RouterModule } from '#angular/router';
import { NgbModule } from '#ng-bootstrap/ng-bootstrap';
#NgModule({

FileListComponent,
NavbarComponent
],

}
]),
],
providers: [ FileDataService,
{ provide: FILE_UPLOAD_URL, useValue: 'http://localhost:8008' }
],
bootstrap: [AppComponent]
})
export class AppModule { }
The CSS is being applied correclty and looks fine. The issue is that none of the javascript is getting executed. For example the toggle for the menu when it goes down to the hamberger does not work. Alerts that are supposed to be dismissable do not react to clicking the "X". I am not sure how to fix this. I don't have any errors in console.
Thanks for any help.
