@utilize/zod

TypeScript/Zod code generator for JSON Schema. Converts any JSON Schema (with references, $defs, definitions) into standalone Zod schemas and TypeScript types.

Features

• Generates standalone Zod schemas for root and all definitions
• Infers TypeScript types from Zod schemas
• Handles all $ref (local, external, cyclic)
• Topologically sorts schemas by dependency
• Supports most of JSON Schema Draft 7

Usage

import { compile } from '@utilize/zod';

await compile({
  input: './schema.json',
  output: './schema.generated.ts',
});

Output

For each standalone schema (root, $defs, definitions, referenced):

export const MyType = z.object({ ... });
export type MyType = z.infer<typeof MyType>;

How it works

• Collects all standalone schemas (root, $defs, definitions, referenced)
• Builds dependency graph and sorts schemas for valid TypeScript output
• Selects the right generator for each schema node
• Emits Zod code and inferred types

When to use

Use this package to automate Zod schema and TypeScript type generation from JSON Schema, including complex schemas with references and modular structure.
