Frequently Asked Questions
How does automatic Zod schema inference work?
The converter inspects keys and primitive types (strings, numbers, booleans, arrays, nested objects) to generate runtime `z.object()`, `z.array()`, and nested schemas.
Can I infer TypeScript types directly from Zod schemas?
Yes. You can use Zod type inference syntax `type MyType = z.infer<typeof mySchema>` or copy the companion TypeScript interfaces generated alongside.
How are union array types inferred?
Arrays containing mixed data structures are analyzed across all items to generate union types like `Array<string | number>` or nested interface unions.
