functional-json-schema

A JavaScript library for building JSON Schema objects using a functional DSL. v1.0.0 (stable, no recent updates). Provides functions to define schema properties, types, arrays, enums, definitions, and $refs in a composable way. Supports Draft-06 and Draft-07. Differentiators: programmatic schema construction with nested object syntax, built-in type helpers, and definition management. Lightweight, no runtime dependencies.
