zod

Zod is a TypeScript-first schema validation library with runtime inference, providing safe parsing for forms, APIs, and configs without codegen.

Chainable API for complex schemas.

Use Zod when:

• Validating TS objects.
• Form libs (React Hook Form).
• API payloads.
• Config safety.

Note: z.object({}).parse(data).

Refine for custom.

SuperRefine for complex.
