Node DTO Mappers v18+

Purpose

Use this skill for DTO mapping in Node.js TypeScript code.

This variant emphasizes transport contracts, normalization, and server-side mapping boundaries where validation and persistence may differ from browser-facing view models.

When to Use

Use this skill when:

• backend services map transport DTOs to domain or persistence shapes
• scripts normalize external payloads
• mapping must sit near validation boundaries

Do

Keep mapping pure and explicit.
