Tool description

Convert TypeScript type to Zod schema automatically. Transform any interface to Zod validation schema or generate Zod from interface definitions without manual rewriting. Perfect for converting TS type to Zod in seconds.

Features

  • Automatically converts interface to Zod schema format with matching validation rules.
  • Transforms TypeScript type to Zod schema including primitives, nested objects, arrays, tuples, literal unions, and optional properties.
  • Detects multiple interfaces and type aliases in a single snippet and generates corresponding Zod constants.
  • Resolves cross-referenced types with z.lazy and highlights fallbacks to z.any().
  • Surfaces structured warnings for unsupported constructs or missing annotations.

Use Cases

  • Generate Zod from interface definitions to bootstrap validation layers from existing TypeScript models.
  • Convert TS type to Zod when migrating from TypeScript-only models to runtime validation.
  • Transform interface to Zod to share contract definitions between frontend and backend without manual duplication.
  • Experiment with TypeScript type to Zod schema conversions when migrating from other validation libraries.

Conversion Details

  • Maps common primitives to z.string(), z.number(), z.boolean(), z.null(), z.undefined(), and z.unknown().
  • Converts literal unions to z.enum([...]) when all members are strings, otherwise falls back to z.union([...]).
  • Generates z.object({...}) for inline object literals and chains .catchall() for index signatures.
  • Produces actionable warnings whenever the converter must fall back to z.any() or skip an interface extension.
