Navigate to Routes

Angular provides both declarative and programmatic ways to navigate between routes.

Declarative Navigation (RouterLink)

Use the RouterLink directive on anchor elements.

import {RouterLink, RouterLinkActive} from '@angular/router';

@Component({
  imports: [RouterLink, RouterLinkActive],
  template: `
    <nav>
      <a routerLink="/dashboard" routerLinkActive="active-link">Dashboard</a>
      <a [routerLink]="['/user', userId]">Profile</a>
    </nav>
  `,
})
export class Nav {
  userId = '123';
}

• Absolute Paths: Start with / (e.g., /settings).
• Relative Paths: No leading /. Use ../ to go up a level.

Programmatic Navigation (Router)

Inject the Router service to navigate via TypeScript code.

router.navigate()

Uses an array of commands.

private router = inject(Router);
private route = inject(ActivatedRoute);

// Standard navigation
this.router.navigate(['/profile']);

// With parameters
this.router.navigate(['/search'], {
  queryParams: { q: 'angular' },
  fragment: 'results'
});

// Relative navigation
this.router.navigate(['edit'], { relativeTo: this.route });

router.navigateByUrl()

Uses a string path. Ideal for absolute navigation or full URLs.

this.router.navigateByUrl('/products/123?view=details');

// Replace current entry in history
this.router.navigateByUrl('/login', {replaceUrl: true});

URL Parameters

• Route Params: Part of the path (e.g., /user/123).
• Query Params: After the ? (e.g., /search?q=query).
• Matrix Params: Scoped to a segment (e.g., /products;category=books).
