I found a project ng2-admin from https://github.com/akveo/ng2-admin , and this is online demo http://akveo.com/ng2-admin/
I am confused about PagesModule bootstrap process. Default AppModule bootstrap, how did it contine show /#/pages/dashboard content?
In app.module.ts:
import { NgModule, ApplicationRef } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { RouterModule } from '#angular/router';
import { NgbModule } from '#ng-bootstrap/ng-bootstrap';
import { TranslateService } from '#ngx-translate/core';
/*
* Platform and Environment providers/directives/pipes
*/
import { routing } from './app.routing';
// App is our top level component
import { App } from './app.component';
import { AppState, InternalStateType } from './app.service';
import { GlobalState } from './global.state';
import { NgaModule } from './theme/nga.module';
import { PagesModule } from './pages/pages.module';
// Application wide providers
const APP_PROVIDERS = [
AppState,
GlobalState
];
export type StoreType = {
state: InternalStateType,
restoreInputValues: () => void,
disposeOldHosts: () => void
};
/**
* `AppModule` is the main entry point into Angular2's bootstraping process
*/
#NgModule({
bootstrap: [App],
declarations: [
App
],
imports: [ // import Angular's modules
BrowserModule,
HttpModule,
RouterModule,
FormsModule,
ReactiveFormsModule,
NgaModule.forRoot(),
NgbModule.forRoot(),
PagesModule,
routing
],
providers: [ // expose our Services and Providers into Angular's dependency injection
APP_PROVIDERS
]
})
export class AppModule {
constructor(public appState: AppState) {
}
}
I know this file is app entrance.
in app.routing.ts file:
import { Routes, RouterModule } from '#angular/router';
import { ModuleWithProviders } from '#angular/core';
export const routes: Routes = [
{ path: '', redirectTo: 'pages', pathMatch: 'full' },
{ path: '**', redirectTo: 'pages/dashboard' }
];
export const routing: ModuleWithProviders = RouterModule.forRoot(routes, { useHash: true });
It only tell browser redirec to "#pages/dashboard", but there is no related component here.
In app.component.ts, the template is:
template: `
<main [class.menu-collapsed]="isMenuCollapsed" baThemeRun>
<div class="additional-bg"></div>
<router-outlet></router-outlet>
</main>
`
There is no other custom tags except router-outlet.
I am confused how to make main AppModule work with PagesModule in application.
Thanks very much.

I'm experimenting with Angular Lazy Load, I have a strange error, while one of the route work flawlessly, while the other (similar structure and implementation) give me an error.
Here is my simple code:
in app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { AppComponent } from './app.component';
const routes: Routes = [
{
path: 'customers',
loadChildren: 'app/customers/customers.module#CustomersModule'
},
{
path: 'orders',
loadChildren: 'app/orders/orders.module#OrdersModule'
},
{
path: '',
redirectTo: '',
pathMatch: 'full'
}
];
#NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
RouterModule.forRoot(routes)
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
while in orders.module.ts
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import { OrdersRoutingModule } from './orders-routing.module';
import { OrderListComponent } from './order-list/order-list.component';
#NgModule({
imports: [
CommonModule,
OrdersRoutingModule
],
declarations: [OrderListComponent]
})
export class OrdersModule { }
and in orders-routing.module.ts
import { NgModule } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { OrderListComponent } from './order-list/order-list.component';
const routes: Routes = [
{
path: '',
component: OrderListComponent
}
];
#NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule]
})
export class OrdersRoutingModule { }
when i go to localhost:4200/orders everything works flawlessly, i.e. no error, and the lazy loading feature works as expected.
while in customers.module.ts
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import { CustomersRoutingModule } from './customers-routing.module';
import { CustomerListComponent } from './customer-list/customer-list.component';
#NgModule({
imports: [
CommonModule,
CustomersRoutingModule
],
declarations: [CustomerListComponent]
})
export class CustomersModule { }
and in customers-routing.module.ts
import { NgModule } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { CustomerListComponent } from './customer-list/customer-list.component';
const routes: Routes = [
{
path: '',
component: CustomerListComponent
}
];
#NgModule({
imports: [RouterModule.forChild(routes)],
exports: [RouterModule]
})
export class CustomersRoutingModule { }
But when i go to localhost:4200/customers it will give me an error:
Error: Component CustomerListComponent is not part of any NgModule or the module has not been imported into your module.
Why is this happening only on customers route? How to fix this?
I'm having an issue with my Angular2/Meteor application.
I'm trying to redirect to a component from an other but it doesn't seem to load the first time. However, when I refresh the page, it loads perfectly.
When I debug, I see my html view without any of the variables displaying, my variables have values that seems correct, but they doesn't show on the View.
This is my Guard:
import { CanActivate } from "#angular/router";
import { Meteor } from 'meteor/meteor';
import { Router } from '#angular/router';
import { Injectable } from '#angular/core';
#Injectable()
export class RouteGuardService implements CanActivate {
constructor(public router: Router) { }
canActivate() {
if (Meteor.userId() != undefined) {
return true;
}
else {
let link = ['accueil'];
this.router.navigate(link);
return false;
}
}
}
My route.module :
import { Route } from '#angular/router';
import {AccueilComponent} from "./pages/accueil/accueil.component";
import {ChannelsComponent} from "./pages/channel/channels.component";
import { RouteGuardService } from './services/routeGuard.service';
export const routes: Route[] = [
{ path: '', component: AccueilComponent },
{ path: 'accueil', component: AccueilComponent, pathMatch: 'full' },
{ path: 'channel', component: ChannelsComponent, canActivate: [RouteGuardService], pathMatch: 'full'},
];
I hope I was clear with my explanation. Do not hesitate to ask more information.
Thanks !
EDIT:
My app.module:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '#angular/forms';
import { RouterModule } from '#angular/router';

import { AccueilComponent } from "./pages/accueil/accueil.component";
import { LOGIN_DECLARATIONS } from './pages/login';

Alright I found an answer. I don't know if it's the best solution, but at least it's working.
this.zone.run(() => this.router.navigate(['channel']));
This solve my problem.
I have an Angular application that navigates to two routes:
http://localhost:8080/ /* Landing page */
http://localhost:8080/details/:id /* Result page */
Whenever I navigate to, for example, http://localhost:8080/details/4235. I'm met with the error: Cannot GET /details/4235
Here is how I setup my routes, in my:
app-routing.module.ts
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { LandingPage } from './components/landingpage/landingpage.component';
import { ResultPage } from './components/resultpage/resultpage.component';
import { TitleService } from './services/title.service';
const routes: Routes = [
{ path: '', component: LandingPage },
{
path: 'details/:id', component: ResultPage, pathMatch: 'full'
}
];
#NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
providers: [TitleService]
})
export class AppRoutingModule { }
Which I import into my:
app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { HttpModule } from '#angular/http';
import { NgModule } from '#angular/core';
import { FormsModule } from '#angular/forms'; // <-- NgModel lives here
import { RouterModule, Routes } from '#angular/router';
import { AppComponent } from './app.component';
import { LandingPage } from './components/landingpage/landingpage.component';
import { ResultPage } from './components/resultpage/resultpage.component';
import { AppRoutingModule } from './app-routing.module';
#NgModule({
declarations: [
AppComponent,
LandingPage,
ResultPage
],
imports: [
BrowserModule,
FormsModule, // <-- import the FormsModule before binding with [(ngModel)]
HttpModule,
AppRoutingModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
I'm having trouble finding a working Angular 2 method of dealing with direct-linking to a url.
How can I setup direct linking in Angular 2, so that when I load, say, http://localhost:8080/details/4235 it loads my ResultPage component.
edit:
Loading http://localhost:8080/#/details/4235 , is valid, but it re-loads the LandingPage component. And I am trying to load the ResultPage component when there is an extended url.
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { LandingPage } from
'./components/landingpage/landingpage.component';
import { ResultPage } from
'./components/resultpage/resultpage.component';
import { TitleService } from './services/title.service';
const routes: Routes = [
{ path: '', component: LandingPage },
{
path: 'details/:id', component: ResultPage
}
];
#NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
providers: [TitleService]
})
export class AppRoutingModule { }
here you're loading the empty path first. Then the other paths will load. Update the empty path route. Keep it at last in the hierarchy.
Updated Code:
import { NgModule } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { LandingPage } from '
./components/landingpage/landingpage.component';
import { ResultPage } from
'./components/resultpage/resultpage.component';
import { TitleService } from './services/title.service';
const routes: Routes = [
{
path: 'details/:id', component: ResultPage
},
{ path: '', component: LandingPage } //<-- here
];
#NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
providers: [TitleService]
})
export class AppRoutingModule { }
EDIT:
Also there might be problem that your browser doesn't support HTML5 pushState. I'm referring some SO links that might help out.

Angular 2.0 router not working on reloading the browser
Repo: https://github.com/leongaban/lifeleveler.io
Not sure why I'm getting this error, I have Router imported in my app.component.ts
I'm trying to use the app.component to hold the main <router-outlet>, and serve up the login view first.
app.module
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { RouterModule } from '#angular/router';
import { routing } from './app.routing';
import { AppComponent } from './app.component';
import { LoginComponent } from './login/login.component';
import { AuthService } from './shared/services/auth.service';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/do';
import 'rxjs/add/observable/throw';
#NgModule({
imports: [
BrowserModule,
FormsModule,
RouterModule,
routing
],
declarations: [
AppComponent,
LoginComponent
],
providers: [
AuthService,
],
bootstrap: [ AppComponent ]
})
export class AppModule {}
app.component.ts
import { Component, OnInit } from '#angular/core';
import { User } from './shared/models/user';
import { Router } from '#angular/router';
#Component({
selector: 'my-app',
templateUrl: './app/app.component.html',
styleUrls: ['./app/app.component.css']
})
export class AppComponent implements OnInit {
ngOnInit() {
}
}
app.component.html
<router-outlet></router-outlet>
app.routing.ts
import { ModuleWithProviders } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { LoginComponent } from './login/login.component';
export const routes: Routes = [
{
path: '',
redirectTo: '/login',
pathMatch: 'full',
},
{
path: 'login',
component: LoginComponent
}
]
export const routing: ModuleWithProviders = RouterModule.forRoot(routes);
I just refactored your project with webpack , your same code works just fine:
github repo
first :
npm install -g #angular/cli
npm install
ng serve
It looks like you might be importing the RouterModule multiple times.
I would remove this line from your app.routing.ts
export const routing: ModuleWithProviders = RouterModule.forRoot(routes);
In your app.module I would import your routes with:
import { routes } from './app.routing';
And then import the RouterModule as:
RouterModule.forRoot(routes)
You should add the RouterModule.forRoot(routes) statement inside your AppModule:
#NgModule({
imports: [
BrowserModule,
FormsModule,
RouterModule.forRoot(routes)
],
declarations: [
AppComponent,
LoginComponent
],
providers: [
AuthService,
],
bootstrap: [ AppComponent ]
})
export class AppModule {}
and remove it from your app.routing.ts file:
export const routes: Routes = [
{
path: '',
redirectTo: '/login',
pathMatch: 'full',
},
{
path: 'login',
component: LoginComponent
}
];
Just import RouterOutlet
import { RouterOutlet } from '#angular/router';
I have a component in angular 2 as shown below
login.component.ts
import { Component } from '#angular/core';
import { LoginViewModel } from "../ViewModel/Login.ViewModel";
import { LoginService } from "../Service/Login.Service";
#Component({
selector: 'login-app',
templateUrl: 'Account/partialLogin',
providers: [LoginViewModel, LoginService]
})
export class LoginComponent {
constructor(private loginservicemodel: LoginService, private model: LoginViewModel) {
this.model.userName = 'erere#ada.com';
this.model.password = "test anand";
}
save(modelValue: LoginViewModel, isValid: boolean) {
if (isValid) {
this.loginservicemodel.loginHttpCall();
}
}
}
Home.Component.ts
import { Component } from '#angular/core';
#Component({
selector: 'Home-app',
template: `
<h1>Angular Router</h1>
<nav>
<a routerLink="/crisis-center" routerLinkActive="active">Crisis Center</a>
<a routerLink="/heroes" routerLinkActive="active">Heroes</a>
</nav>
<router-outlet></router-outlet>
`
})
export class HomeComponent {
}
The appModule.ts
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { RouterModule, Routes } from '#angular/router';
import { HttpModule, JsonpModule } from '#angular/http';
import { LoginComponent } from "./Components/login.Component";
import { HomeComponent } from "./Components/home.component";
const appRoutes: Routes = [
{ path: '', component: HomeComponent },
{ path: 'Account/Login', component: LoginComponent }
];
#NgModule({
imports: [BrowserModule, FormsModule, HttpModule, JsonpModule, RouterModule.forRoot(appRoutes)],
declarations: [LoginComponent, HomeComponent],
bootstrap: [HomeComponent]
})
export class AppModule { }
login.cshtml
#{
ViewData["Title"] = "Login";
}
<login-app>looding...</login-app>
partialLogin.cshtml
<router-outlet></router-outlet>
<p>THis is test</p>
Routing
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
routes.MapRoute(
name: "spa-fallback",
template: "{*url}",defaults: new { controller = "Home", action = "Index" });
});
I have use the angular 2 routing as you can see in the appmodule.ts.If I navigate to homepage i,e Home/Index I will get an error as The selector "login-app" did not match any elements and when I navigate to Account/Login I will get an error as The selector "Home-app" did not match any elements.I know the the condition on appmodule is not working. How can I make this work. Please anyone can solve this issue
you are getting this error because you didn't import all your other component in you ngModule file. add them in declaration just like you have imported LoginComponent
#NgModule({
imports: [BrowserModule, FormsModule, HttpModule, JsonpModule],
declarations: [LoginComponent],<-- add all your component here
bootstrap: [LoginComponent]
})
export class AppModule { }
Below is an example of how to add route in Angular2:
//Create new app.module.ts file
import { ModuleWithProviders } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
import { LoginComponent } from './Components/login.Component';
const appRoutes: Routes = [
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'login', component: LoginComponent}
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);
//Import the above define route in your App module
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { HttpModule, JsonpModule } from '#angular/http';
import { LoginComponent } from "./Components/login.Component";
//Import your route file
import { routing } from './app.routing';
#NgModule({
imports: [BrowserModule, FormsModule, HttpModule, JsonpModule,routing,],
declarations: [LoginComponent],
bootstrap: [LoginComponent]
})
export class AppModule { }
Finally the working code.Call the respective selector in HTML page
AppModule.ts
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { FormsModule } from '#angular/forms';
import { RouterModule, Routes } from '#angular/router';
import { HttpModule, JsonpModule } from '#angular/http';
import { ModuleWithProviders } from '#angular/core';
import { AppComponent} from "./app.component";
import { LoginComponent } from "./Components/login.Component";
import { HomeComponent } from "./Components/home.component";
const appRoutes: Routes = [
{ path: '', redirectTo: 'Home/Index', pathMatch: 'full' },
{ path: 'Account/Login', component: LoginComponent },
{ path: 'Home/Index', component: HomeComponent }
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);
#NgModule({
imports: [BrowserModule, FormsModule, HttpModule, routing],
declarations: [AppComponent,LoginComponent, HomeComponent],
bootstrap: [AppComponent]
})
export class AppModule { }
app.Component.ts
import { Component } from '#angular/core';
import { Routes, RouterModule } from '#angular/router';
#Component({
selector: 'main-app',
template: '<router-outlet></router-outlet>'
})
export class AppComponent { }
Home.Component.ts
import { Component } from '#angular/core';
#Component({

template: `

<nav>
<a routerLink="/crisis-center" routerLinkActive="active">Crisis Center</a>
<a routerLink="/heroes" routerLinkActive="active">Heroes</a>
</nav>
`
})
export class HomeComponent {
}
login.Component.ts
import { Component } from '#angular/core';
import { LoginViewModel } from "../ViewModel/Login.ViewModel";
import { LoginService } from "../Service/Login.Service";
#Component({
selector: 'login-app',
templateUrl: 'Account/partialLogin',
providers: [LoginViewModel, LoginService]
})
export class LoginComponent {
constructor(private loginservicemodel: LoginService, private model: LoginViewModel) {
this.model.userName = 'erere#ada.com';
this.model.password = "test anand";
}
save(modelValue: LoginViewModel, isValid: boolean) {
if (isValid) {
this.loginservicemodel.loginHttpCall();
}
}
}
