Go Mapper

Generate pure mapper functions for GO modular architecture.

When to Use

• Map HTTP request DTOs to use case inputs
• Map persistence models to HTTP response DTOs
• Map between any two struct representations across layers
• Convert a slice of structs to a slice of another struct
• Any struct-to-struct transformation that lives in a module

Location

All mapper files live in internal/modules/<module>/mapper/.

One file per domain concept: <name>_mapper.go (e.g., user_mapper.go).
