Why Convert Zod Schemas?

Zod is the most popular TypeScript-first schema validation library, used by millions of developers for runtime data validation. However, maintaining separate Zod schemas, TypeScript interfaces, and database models creates duplication and synchronization bugs. Our converter bridges this gap by generating type definitions directly from your Zod schemas.

Supported Zod Types

Primitives: z.string(), z.number(), z.boolean(), z.date(), z.bigint()
Modifiers: .optional(), .nullable(), .default(), .array()
Enums: z.enum(['a', 'b', 'c'])
Arrays: z.array(z.string())
Objects: Nested z.object({...})
Validators: .min(), .max(), .email(), .uuid(), .url(), .int()

Prisma Output Notes

When converting to Prisma, Zod types are mapped to Prisma field types: z.string() becomes String, z.number() becomes Int (or Float if not .int()), z.boolean() becomes Boolean, and z.date() becomes DateTime. Nested objects are converted to Json type since Prisma does not support inline nested models.

Tip: For the best results, use standard Zod patterns. Our parser uses regex-based analysis, so complex dynamic schemas or Zod transforms may need manual adjustment after conversion.

Zod in the TypeScript Ecosystem

Zod has become the de facto standard for runtime validation in TypeScript projects. It is natively integrated with popular frameworks: tRPC uses Zod schemas to define API input/output types with end-to-end type safety. React Hook Form supports Zod via @hookform/resolvers/zod for form validation. Next.js server actions commonly use Zod for input validation. Astro uses Zod for content collection schemas. The key advantage of Zod over alternatives like Yup or Joi is that Zod infers TypeScript types directly from schemas using z.infer<typeof schema>, eliminating the need to maintain separate type definitions.

TypeScript vs Prisma Output: When to Use Each

Choose TypeScript Interface output when you need type definitions for API request/response types, React component props, or Redux/Zustand store types. The generated interfaces include optional markers (?) for .optional() fields and union types for .nullable(). Choose Prisma Model output when designing or updating your database schema. The converter maps Zod validators to Prisma attributes: .uuid() adds @default(uuid()), .email() or .url() are preserved as comments, and .default() values are mapped to Prisma @default() attributes.

Schema-First Development Workflow

The recommended workflow for TypeScript projects is schema-first development: define your data model once as a Zod schema, then derive everything else from it. From a single Zod schema you can generate TypeScript types (via z.infer), form validation (via React Hook Form + Zod resolver), API contracts (via tRPC or manual validation), and now database models (via this converter). This “single source of truth” pattern eliminates the class of bugs where your frontend type, API validation, and database model drift out of sync over time.

Disclaimer: Generated TypeScript interfaces and Prisma models are produced by regex-based parsing and may require manual adjustment for complex types, deeply nested objects, Zod transforms, refinements, and discriminated unions. Always review generated code before use in production.
