json-schema-ref-resolver

JavaScript library that resolves $ref references in JSON Schemas, part of the Fastify ecosystem. Current stable version is 3.0.0, released with TypeScript type definitions and following semver. It resolves internal and external schema references, supports dereferencing, and provides schema dependency tracking. Unlike json-schema-ref-parser, it is lightweight, synchronous, and focused on Fastify-like use cases. Key differentiators: no dependencies, simple API, and support for circular references with optional Symbol insertion.
