# Routing

## **Priority: P0 (CRITICAL)**

## 1. Lazy Load All Feature Routes

- Use `loadComponent` (standalone) or `loadChildren` (route file) for every feature route.

See [routing patterns](references/routing-patterns.md) for lazy loading and guard examples.

## 2. Use Functional Guards

- Create function-based guards (`CanActivateFn`) instead of deprecated class-based guards.

See [routing patterns](references/routing-patterns.md) for functional guard implementation.

## 3. Enable Component Input Binding

- Configure `withComponentInputBinding()` in `provideRouter(routes, withComponentInputBinding())`.
- Define `input.required<string>()` in components — Angular auto-maps route params, query params, and resolve data.

## 4. Configure Resolvers and Titles

- Create `ResolveFn<T>` to pre-fetch critical data before navigation.
- Provide custom `TitleStrategy` or use `title: 'Dashboard'` in route data.

## Anti-Patterns

- **No logic in route config**: Move access control and data fetching to dedicated Guards and Resolvers.
- **No eager feature imports**: Use `loadComponent` or `loadChildren` for all feature routes.
