SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you avoid runtime shape errors by standardizing Zod v4 schema validation patterns and preventing common migration mistakes from Zod v3, especially when integrating with Drizzle ORM and React Hook Form.

Core Features & Use Cases

  • Zod v4 validation patterns: Safe parsing with safeParse, correct error message APIs, and reliable handling of ZodError behavior changes.
  • Schema composition for maintainable types: Use of extend, pick, and discriminatedUnion to model real domain events and inputs cleanly.
  • Integration recipes: Guidance for drizzle-zod (Zod v4 compatibility) and React Hook Form using zodResolver with updated resolver type expectations.

For example, use it when validating a login form by defining a Zod v4 schema, wiring it into React Hook Form, and ensuring the same shape is compatible with database insert/select schemas via drizzle-zod.

Quick Start

Ask the AI to generate a Zod v4 schema for your data shape (including custom error messages) and show how to plug it into Drizzle ORM schemas and React Hook Form via zodResolver.

Frequently Asked Questions about zod-validation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I migrate Zod v3 schemas to Zod v4 error message APIs?▼

To migrate Zod v3 to Zod v4, update your error message APIs, adjust ZodError behavior, and verify safe parsing practices to maintain reliable typed input and output boundaries.

How do I integrate Zod v4 schemas with React Hook Form and zodResolver?▼

Integrating Zod v4 with React Hook Form requires using zodResolver with updated resolver type expectations to ensure your form validation schemas map correctly to your inputs.

Can I use drizzle-zod for Zod v4 schema validation with Drizzle ORM?▼

Yes, you can use drizzle-zod for Zod v4 compatibility by ensuring your database insert and select schemas align with your validation schemas to maintain consistent typed boundaries.

What is the best way to model complex domain events using Zod v4?▼

The best way to model complex domain events in Zod v4 is using schema composition techniques like extend, pick, and discriminatedUnion to cleanly structure real inputs and object key handling semantics.

Why does safeParse behave differently after updating to Zod v4?▼

SafeParse behavior changes in Zod v4 due to updated ZodError handling and error message APIs, requiring adjustments to your parsing logic to maintain correct runtime validation shapes.

Does Zod v4 support NDJSON and API request validation flows?▼

Yes, Zod v4 supports NDJSON and API validation flows by applying safe parsing practices and discriminated union modeling to enforce reliable typed input and output boundaries.
