NestJS feature modules within a bounded context are structured by creating one dedicated module per feature, isolating providers, and exporting only public applications to maintain strict architectural boundaries.

NestJS layered architecture injection rules dictate which specific layers can inject dependencies and when to register providers directly in the ApplicationModule to prevent cross-boundary coupling and maintain module isolation.

You need to register providers in the NestJS ApplicationModule when following layered architecture rules to explicitly control dependency injection scope and ensure providers are available to the correct feature layers.

The best way to export public applications from a NestJS module is to use the module's exports array exclusively for application services, keeping internal domain providers private to enforce bounded context encapsulation.

Yes, you can use bounded context modules to organize a large NestJS monolith by isolating features into distinct modules, which significantly improves overall maintainability and testability without requiring microservices.

NestJS feature module circular dependency issues occur when layered architecture rules are violated and modules inject across bounded contexts, requiring you to restrict exports to public applications and restructure provider registration.
