openapi-response-validator

A library to validate HTTP responses against OpenAPI (Swagger) schemas. v12.1.3 is the current stable release, maintained as part of the open-api monorepo. It uses jsonschema under the hood and supports $ref in response definitions, custom error transformers, and custom formats. Lightweight and focused solely on response validation, unlike full OpenAPI validators like express-openapi-validator. Released on GitHub with consistent versioning.
