  role: z.enum(["admin", "user"])
});
Generated TypeScript Interface Processed 
export interface User {
  id: string;
  name: string;
  bio?: string;
  role: "admin" | "user";
}

Frequently Asked Questions

Why convert Zod schemas to static TypeScript interfaces?
Generating static TypeScript types allows lightweight clients and API packages to consume type contracts without bundling the full Zod validation library.

Fields with .optional() receive the TypeScript ? modifier, .nullable() fields receive | null, and .nullish() fields receive both ? and | null.
Is my Zod code sent to any external server?
No. All parsing and transpilation occurs 100% in-browser with zero network calls and complete privacy.
