JSON to Zod - TypeScript Schema Generator

Why Zod?

Zod is a TypeScript-first schema validation with static type inference. It validates data at runtime and automatically infers TypeScript types.

Common Use Cases

• Form Validation — Validate form inputs with detailed error messages
• API Validation — Validate request/response data in Next.js API routes
• tRPC — Type-safe API procedures with input/output validation
• Configuration — Validate environment variables and config files

Example Usage

import { z } from "zod";

// Generated schema
const UserSchema = z.object({
  id: z.number().int().positive(),
  email: z.string().email(),
  name: z.string().min(1)
});

// Inferred TypeScript type
type User = z.infer<typeof UserSchema>;

// Runtime validation
const user = UserSchema.parse(jsonData);
