Query parameters in Angular allow for passing optional parameters across any route in the application. Query parameters are different from regular route parameters, which are only available on one route and are not optional (e.g., /product/:id).

{ path: 'crisis-center/:param1', component: CrisisListComponent },

];
@NgModule({
imports: [
RouterModule.forRoot(
appRoutes,
{ enableTracing: true }
)
],
