TypeBox

TypeBox is a runtime type system that constructs JSON Schema objects from TypeScript-like type definitions, automatically inferring static TypeScript types via Type.Static. The current stable version is 1.1.36, with frequent releases following semantic versioning. It differentiates itself by providing a unified type system that works both at compile time (TypeScript type checking) and runtime (JSON Schema validation), making it ideal for API validation, data serialization, and building type-safe protocols. Unlike standalone validators like Ajv or Zod, TypeBox focuses exclusively on schema generation and type inference, leaving validation to JSON Schema validators.
