Angular Router ले URL paths लाई components सँग म्याप गर्छ, जसले पूर्ण पृष्ठ पुनः लोड बिना single-page app मा navigation सक्षम गर्छ। तपाईले paths लाई components सँग जोडने route configuration array परिभाषित गर्नुहुन्छ।
{ } ;
: = [
{ : , : },
{ : , : },
{ : , : },
{ : , : ().( m.) },
{ : , : },
];
<!-- the router renders the matched component here -->
<router-outlet></router-outlet>
<a routerLink="/users" routerLinkActive="active">Users</a>
<a [routerLink]="['/users', user.id]">View {{ user.name }}</a> <!-- dynamic path -->
routerLink ले client-side navigation (कुनै पुनः लोड छैन) गर्छ, र routerLinkActive ले CSS class थप गर्छ जब link को route सक्रिय हुन्छ — nav हाइलाइटिंगको लागि उपयोगी।
import { Router } from "@angular/router";
export class LoginComponent {
constructor(private router: Router) {}
onLogin() {
this.router.navigate(["/dashboard"]); // navigate after an action
}
}
import { ActivatedRoute } from "@angular/router";
export class UserDetailComponent implements OnInit {
constructor(private route: ActivatedRoute) {}
ngOnInit() {
// read :id from the URL (params is an Observable, since it can change)
this.route.params.subscribe(p => this.userId = p["id"]);
// or snapshot for a one-time read:
const id = this.route.snapshot.paramMap.get("id");
}
}
Nested/child routes, route guards (auth), resolvers (pre-fetch data),
query params, and lazy loading of feature routes for code splitting.
Router यो हो जसले Angular लाई multi-view SPA मा परिणत गर्छ — द्रुत client-side navigation, URL-driven UI, र deep-linkable pages।
Route config, <router-outlet>, routerLink vs programmatic Router.navigate, र ActivatedRoute को माध्यमबाट params पढ्न जानेकोले कुनै पनि Angular application को दैनिक routing आवश्यकताहरु पूरा गर्छ, जसमा guards र lazy loading यो foundation मा निर्मित हुन्छ।
