http-problem-details-mapper

A library for mapping errors to RFC 7807 HTTP Problem Details (ProblemDocument) objects. Version 0.1.7 ships TypeScript types and follows Conventional Commits. It provides an extensible mapper pattern (ErrorMapper, MapperRegistry, MappingStrategy) to convert domain errors into structured HTTP error responses. Key differentiators: integrates with http-problem-details and express-http-problem-details for a complete REST error handling stack. Release cadence is low; version 0.1.x is stable and maintained. Peer dependency on http-problem-details (^0.1.0) required.
