Zod Documentation

Complete Zod validation library documentation embedded in markdown. Read from references/ to answer questions about schema validation, type inference, and error handling.

Documentation Structure

All documentation is in references/ organized by topic:

Core Documentation

- Primitives (string, number, boolean, etc.) - Complex types (object, array, tuple, union, etc.) - Schema methods (parse, safeParse, parseAsync, etc.) - Refinements and transforms - Type inference - Error handling

Advanced Features

• error-formatting.mdx - Error formatting and customization
• error-customization.mdx - Custom error messages
• codecs.mdx - Serialization and deserialization
• json-schema.mdx - JSON Schema generation
• metadata.mdx - Schema metadata

Integration & Ecosystem

• ecosystem.mdx - Community packages and integrations
• library-authors.mdx - Guide for library authors

Quick Reference

Common Tasks

Schema Examples

Primitives:

z.string()
z.number()
z.boolean()
z.date()
z.undefined()
z.null()
z.any()
z.unknown()

Complex Types:

z.object({ ... })
z.array(z.string())
z.tuple([z.string(), z.number()])
z.union([z.string(), z.number()])
z.record(z.string())
z.map(z.string(), z.number())
z.set(z.string())

Refinements:

z.string().email()
z.string().url()
z.string().uuid()
z.number().min(5).max(10)
z.string().regex(/pattern/)

Transforms:

z.string().transform(val => val.toUpperCase())
z.coerce.number()

When to Use This Skill

• Form validation in React/Next.js
• API request/response validation
• Environment variable parsing
• Runtime type checking
• Data transformation and parsing
• Error message customization
• Integration with tRPC, React Hook Form, etc.
• TypeScript type inference from schemas

How to Navigate

1. Start with index.mdx for introduction
2. For basic usage: Read basics.mdx
3. For API details: Check api.mdx (comprehensive reference)
4. For error handling: See error-formatting.mdx and error-customization.mdx
5. For advanced features: Browse codecs.mdx, json-schema.mdx, metadata.mdx
6. For integrations: Check ecosystem.mdx
7. For v4 features: See v4/ directory

All files are .mdx (Markdown + JSX) but readable as plain markdown.
