openapi-json-schema

Minimalistic OpenAPI 3 to JSON Schema (draft 7) conversion library. v2.0.0 is pure ESM, requires Node >=14.13.1. No dependencies. Supports nullable, $ref conversion between #/definitions and #/components/schemas, const to enum, $id/$comment to x-id/x-comment. Does not resolve JSON $refs. Differentiator: zero dependencies, focused conversion without resolution.
