Structure mapping
title, version | → info |
baseUri | → servers |
/resource | → paths (nested joined) |
types | → components.schemas |
body | → requestBody |
Type mapping
Order[] | → type: array, items |
type: Order | → $ref |
name?: | → optional (not in required) |
datetime | → string, format: date-time |
string | number | → oneOf |
Good to know
| Accepts YAML or JSON input |
| Nested resources are path-joined |
| Security schemes are mapped best-effort |
| Advanced features (traits, resourceTypes, callbacks) are flagged, not dropped |
| Everything runs locally — safe for private specs |
