Route-level providers in Angular are configured by registering providers directly within route definitions. This scopes dependencies to specific feature modules, improving tree-shaking and ensuring predictable provider wiring across enterprise application boundaries.

The best way to decouple domain and infrastructure layers in Angular is by defining InjectionToken repositories at the domain level. This pattern standardizes infrastructure provider organization by centralizing API clients and use cases, enabling predictable wiring and dependency replacement.

Using the inject() function in Angular replaces constructor injection by allowing dependencies to be assigned directly to class properties. This simplifies lifecycle handling and standardizes dependency injection patterns, reducing boilerplate errors in module setup.

Lazy loading in Angular works by using loadComponent and loadChildren to enable code-splitting and modular architecture. This pattern allows feature boundaries to load on demand, reducing initial bundle size and organizing infrastructure providers predictably across routes.

Explicit DestroyRef should be used with route-level providers in Angular when managing infrastructure-provider organization across feature boundaries. It ensures predictable cleanup of dependencies scoped to lazy-loaded modules, satisfying enterprise architecture patterns for explicit lifecycle control.
