Passing parameters in Angular routes may result in routes not being able to match

I am facing an issue while trying to access a component that requires 2 URL parameters. Despite providing the parameters, I encounter an error indicating that the routes cannot be matched.

const routes: Routes = [
{
    path: 'home',
    component: HomeComponent
},
{
    path: 'home/:dataClass',
    },
    canActivate: [ProtectedRoutesGuard],
    component: DataViewerRouteComponent,
},
{ // ISSUE OCCURS BELOW

    path: '/:dataClassName/:id',
    data: {
        name: 'Service Status'
    },
    component: DataViewerRecordsComponent,
},
{ 
    pathMatch: 'full',
    path: '',
    data: {
        name: 'Service Status',
        module: ['data-viewer']
    },
    canActivate: [ProtectedRoutesGuard],
    component: DataViewerHomeComponent,
},
{
    pathMatch: 'full',
    path: '**',
    redirectTo: '/data-viewer',
}

];

Here is how the navigation is implemented:

this.router.navigate([this.dataClassName + '/' + this.id]);

The data is correctly assigned to the route, but it fails to match any available routes, resulting in the following error message:

core.js:4002 ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'benchmarks/101723102'

Error: Cannot match any routes. URL Segment: 'required/1234'

Answer №1

Consider structuring your routing in the following way:

this.router.navigate(['/'+this.selectedData], {queryParams: {'identifier': this.identifier}});

Afterwards, ensure that you properly handle and parse the queryParams within the target component.

Answer №2

navigateByUrl vs navigate

When it comes to navigation in Angular, you have two options: navigateByUrl and navigate.

Using navigateByUrl:
this.router.navigateByUrl(`/${this.dataClassName}/${this.id}`);

Using navigate:
this.router.navigate([`/${this.dataClassName}`, this.id]);

Keep in mind that it's recommended not to use parameters only in your route. Also, avoid starting a Route definition with /.
