My component fails to load using Angular Router even though the URL is correct

I have been experiencing an issue while trying to load my Angular component using the router. The component never appears on the screen and there are no error messages displayed.

app-routing-module

  
{ path: '', redirectTo: '/home', pathMatch: 'full' },
{
    path: 'home', component: HomeComponent, children:
      [
        { path: 'compare', component: CompareComponent, children: [] },
        {
          path: 'settings', component: SettingsComponent, children: [
            { path: 'new', component: ServerConnectionEditComponent }
          ]
        },
      ]
  },

app-server-connections

  
constructor(private router:Router, private route:ActivatedRoute) { }
onAddServer()
{
    console.log(this.route.url)
    this.router.navigate(['new'], {relativeTo: this.route});
}

The URL appears to be valid because any other URL triggers an error.

app-server-connection-edit

  
ngOnInit() {
    console.log("in Edit") //never gets here
}

server-connections.component.html

...
<th scope="col"><button type="button" class="btn btn-success btn-sm"
                  (click)="onAddServer()">+</button></th>

app-component.html

<app-header></app-header>
<div class="container">
  <div class="row">
    <div class="col-md-12"> 
      <router-outlet></router-outlet>
    </div>
  </div>
</div>

settings.component.html

<div class="container">
  <div class="row">
    <div>
      <div class="col-md-12" >
        <h4>Server Connections:</h4>
      </div>
      <br/>
      <div class="col-xs-12">
          <app-server-connections [serverConnections]="serverConnections"></app-server-connections>
      </div>
    </div>
  </div>
</div>

Answer №1

Ensure that you only have a single level nested child in your route structure. Modify your route as shown below. If the issue persists, check the browser console for any errors.

{
    path: 'home', component: HomeComponent, children:
    [
        { path: 'compare', component: CompareComponent },
        {
            path: 'settings/new', component: ServerConnectionEditComponent

        },
        { path: 'settings', component: SettingsComponent }
    ]
}

Also, remember to include

<router-outlet></router-outlet>
within your app.component.html file

Answer №2

The rule of specificity dictates that the more specific must take precedence over the less specific. Therefore, settings/new should be prioritized over settings.
