Mapper Layer

This package provides mappers to convert data between various layers such as:

• Database records
• API responses
• Proto (gRPC) messages
• Service domain logic

Each subdirectory is organized by conversion type and grouped by feature/domain (e.g., Auth, User, Topup).

Structure

• record/: Maps from database models to internal record representations.
• response/: Maps from records to API/service responses.
  • api/: Used in controller/handler layer for HTTP/gRPC responses.
  • service/: Used within services to transform internal models into service outputs.
• proto/: Maps between proto (gRPC) messages and domain models.

All mappers implement interfaces for maintainability and ease of testing.
