To add a presentation layer to a bounded context, create a standardized REST directory structure including request, response, and controller components, ensuring data flows through DTOs instead of domain VOs.

Using DTOs instead of domain VOs in a REST API presentation layer enforces clean separation between the presentation and domain layers, maintaining consistent data flow and preventing domain logic from leaking into the API structure.

The standard RESTful presentation layer directory structure organizes code into specific subdirectories such as rest/request, rest/response, and rest/controller to maintain architectural consistency within a bounded context.

You can update an existing presentation layer safely by modifying the rest structures and DTOs, which constrains implementation to a DTO-based data flow and preserves the bounded context architecture.

You need to separate presentation DTOs from domain VOs when implementing a RESTful presentation layer, as it enforces a DTO-based data flow and standardizes the boundary between API endpoints and domain logic.

The best way to structure controllers and DTOs in a bounded context is to follow a standardized rest directory layout that separates request, response, and controller files while enforcing DTO-based data flow over domain VOs.
