SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provide clear patterns for validating data with Zod v4, enabling reliable schema creation and consistent parsing across forms and API payloads.

Core Features & Use Cases

  • Zod v4 patterns for primitive and object schemas, including z.string(), z.number(), z.object, and z.infer.
  • Validation and parsing for forms, API payloads, and DTOs, with clear error messages and type inference.
  • Real-world example: defining a User schema with id, email, and age, and parsing input safely.

Quick Start

Create a Zod v4 schema to validate a user input payload.

Frequently Asked Questions about zod-4

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

FAQPage Schema
How do I validate API payloads in TypeScript using Zod?▼

You can validate API payloads in TypeScript using Zod by defining object schemas with z.object and parsing incoming data with z.safeParse to ensure type safety and clear error messages.

What is the best way to infer TypeScript types from Zod schemas?▼

The best way to infer TypeScript types from Zod schemas is by using z.infer, which automatically generates static types from your schema definitions for safe API data handling.

How do I safely parse form data without throwing errors in Zod?▼

To safely parse form data without throwing errors, use the z.safeParse method on your Zod schema, which returns a structured success or error object instead of throwing an exception.

Can I define modular object schemas for DTOs with Zod v4?▼

Yes, you can define modular object schemas for DTOs with Zod v4 by composing primitive schemas like z.string and z.number into z.object structures for reliable data validation.

Does Zod v4 support primitive schema validation for user inputs?▼

Zod v4 fully supports primitive schema validation for user inputs, allowing you to validate strings, numbers, and other primitives before processing form or API request data.
