graphql-to-jsonschema

Converts GraphQL Schema Definition Language (SDL) to JSON Schema (draft-04). Version 1.0.0. Supports scalars (including custom), enums, unions, object types with required fields, lists, and recursive references. Output is compatible with react-jsonschema-form. No active releases since initial 2016. Differentiators: simple string-to-object conversion without GraphQL execution, ESM-only via npm package. Caveats: no support for interfaces, input types, directives, or deprecation. Output uses non-standard types like GRAPHQL_SCALAR for custom scalars and GRAPHQL_UNION.
