graphql-json-schema

Converts GraphQL Schema Language (SDL) to JSON Schema (draft-04). Stable version 0.1.2, low release cadence. Differentiates by enabling reuse of GraphQL type definitions in JSON Schema contexts; outputs definitions with GraphQL-specific constructs (e.g., GRAPHQL_SCALAR, GRAPHQL_UNION) rather than fully standard JSON Schema, which may require post-processing.
