Deterministic, self-contained JSON Schema Draft 2020-12 documents generated from Lucid schemas.

import { toJsonSchema } from "@lucid-softworks/schema-json-schema";

const document = toJsonSchema(userSchema, {
  id: "https://example.com/schemas/user",
  title: "User",
});

Every component receives a stable local $defs reference, including recursive lazy schemas. Runtime-only refinements, preprocessing, transformations, defaults, and pipelines are annotated with x-lucid-* keywords by default. Set { runtimeEffects: "error" } to reject those lossy conversions instead.

Object schemas that strip unknown keys emit additionalProperties: true because JSON Schema validates but does not transform input. Strict objects emit additionalProperties: false.
