Routing

Priority: P0 (CRITICAL)

Principles

• Lazy Loading: All feature routes MUST be Lazy load all features with loadComponent (standalone) or loadChildren (route file).
  • Example:

    { path: 'dashboard', loadComponent: () => import('./features/dashboard/dashboard.component').then(m => m.DashboardComponent) }

    .
• Functional Guards: Use function-based guards (CanActivateFn) instead of class-based guards (guards are deprecated).
  • Example:

    export const authGuard: CanActivateFn = () => inject(AuthService).isAuthenticated() ? true : inject(Router).createUrlTree(['/login'])

    . Register in routes:

    { canActivate: [authGuard] }

    .
• Component Inputs: Enable withComponentInputBinding() in provideRouter(routes, withComponentInputBinding()) to define input.required<string>() in components. Angular auto-maps route params, query params, and resolve data to matching inputs.

Guidelines

• Title Strategy: Provide a custom TitleStrategy service (extending

  TitleStrategy

  and overriding updateTitle(snapshot)) or use simple title: 'Dashboard' in route data.
• Resolvers: Create a ResolveFn<User> (e.g., inject(UserService).getUser(route.paramMap.get('id'))) to pre-fetch critical data before navigation completes (resolve: { user: userResolver }). Avoid blocking UI too long.

Anti-Patterns

• No logic in route config: no logic inside route config. Move guards for access control and data fetching to dedicated Guards and Resolvers.
• No eager feature imports: Use

  loadComponent

  or

  loadChildren

  for all feature routes.
