Package Exports

json-schema-to-zod
json-schema-to-zod/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-schema-to-zod) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

jsonSchemaToZod will output the full module code, including a Zod import. If you only need the Zod schema itself, try one of the parsers directly. If you need to deref your JSON schema, try awaiting jsonSchemaDereffed.

import {
  jsonSchemaToZod,
  jsonSchemaToZodDereffed,
  parseSchema,
} from "json-schema-to-zod";

const myObject = {
  type: "object",
  properties: {
    hello: {
      type: "string",
    },
  },
};

const module = jsonSchemaToZod(myObject);

const dereffed = await jsonSchemaToZodDereffed(myObject);

const schema = parseSchema(myObject);

module/dereffed =

import { z } from "zod";

export default z.object({ hello: z.string().optional() });

schema =

z.object({ hello: z.string().optional() });
