Angular 2 router error - javascript

I created Angular 2 router module but it doen't work at the moment and I get an error when I want to open link /city 'ERROR Error: Uncaught (in promise): Error: Cannot activate an already activated outlet
Error: Cannot activate an already activated outlet'
But I can open this link manually
Here is the code of:
Router module
import { NgModule }from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import {WeatherListComponent} from "../weather-list/weather-list.component";
import {AddedCityComponent} from "../added-city/added-city.component";

{ path: 'city', component: AddedCityComponent },

try
const routes: Routes = [
{ path: 'city', component: AddedCityComponent },
{ path: 'weather-list', component: WeatherListComponent },
{ path: '', redirectTo: '/weather-list', pathMatch: 'full'}
];
and move appRoutingModule to the start of the list in the imports declaration

i see that you don't have router-outlet in your App component. Try to copy this code in your app.component.html :
<router-outlet></router-outlet>
then try to enter to open links.

Remove the leading slashes in the /weather-list to weather-list. This will make the first path work which might be causing the problem. Just try this out and let me know.

It looks as though your routerLinks are not setup correctly in the component html.
Try changing your link tags from ...
<a routerLink="/city" routerLinkActive="active">cities</a>
<a routerLink="/weather-list" routerLinkActive="active">weather</a>
To ...
<a [routerLink]="['/city']" routerLinkActive="active">
<a [routerLink]="['/weather-list']" routerLinkActive="active">
You might also try removing the .forRoot on your routing module import, I am not sure that it is necessary in this case.

I have tried different combination to solve the issue but still not able to get rid of this error,
what am I doing wrong in my code? any help will be helpfull thanks
When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink], then it should be assigned a name of the property the value of which will be the route it should navigate the user to.
So to fix your issue, replace this routerLink="['/about']" with routerLink="/about" in your HTML.
There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:
<nav class="main-nav>
<ul
class="main-nav__list"
ng-sticky
addClass="main-sticky-link"
[ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/">Home</a>
</li>
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/about">About us</a>
</li>
</ul>
</nav>
It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>, either in your template provided above or in a parent component.
There's another issue with your AppRoutingModule. You need to export the RouterModule from there so that it is available to your AppModule when it imports it. To fix that, export it from your AppRoutingModule by adding it to the exports array.
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import { RouterModule, Routes } from '#angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
{ path: 'about', component: AboutComponent },
{ path: 'what', component: WhatwedoComponent },
{ path: 'contacts', component: FooterComponent },
{ path: 'projects', component: ProjectsComponent},
];
#NgModule({
imports: [
CommonModule,
RouterModule.forRoot(routes),
],
exports: [RouterModule],
declarations: []
})
export class AppRoutingModule { }
In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:
[routerLink]="['edit', business._id]"
As for an "about page" with no parameters like yours,
[routerLink]="/about"
or
[routerLink]=['about']
will do the trick.
As the error says your router link should match the existing routes configured
It should be just routerLink="/about"
i founded the correct answer by search of many days ;
just convert routerLink="['/jkh',id]"
to
[routerLink]="['/jkh',id]"
and give it all the requerments and its solve
;
You need to use:
[routerLink]="/about"
If you wanted to pass a parameter like id, lets say like a course with an id parameter you will need to use it like this:
[routerLink]="['/course/', course.id]"
It should help any related error.

Direct loading routes in Angular 2

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.

This is the code i used in my project. but the routing is not working .
What is the wrong in my code. actually i have markup in my ./blank.component.html which i not included in the question. now the page displaying is the content in app.component.html only
You need to give the component name at {path:'home',component:ComponentName,loadChildren: '../pages/dashboard/dashboard.module#DashboardModule'}
