graphql-scalars

A comprehensive library of custom GraphQL scalar types for precise type-safe schemas. Current stable version is 1.25.0, with regular releases. It provides over 40 scalars (DateTime, JSON, UUID, Email, etc.) not included in base GraphQL, supporting GraphQL v0.8 to v16. Maintained by The Guild, it ships TypeScript definitions and is ESM- and CJS-compatible. Key differentiators: extensive scalar collection, active maintenance, broad GraphQL version support, and detailed documentation on graphql-scalars.dev.
