SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers write more reliable TypeScript code by enforcing best practices for Zod schema definition, validation, and error handling, preventing runtime errors and improving code quality.

Core Features & Use Cases

  • Schema Definition: Guides on using correct primitives, avoiding z.any(), and applying string validations.
  • Parsing & Validation: Best practices for safeParse(), async validation, and validating at system boundaries.
  • Error Handling: Strategies for custom messages, internationalization, and user-friendly error display.
  • Use Case: Ensure all incoming API request bodies are validated against a Zod schema, catching invalid data early and returning clear error messages to the client.

Quick Start

Use the zod skill to validate an incoming JSON payload against the userSchema using safeParse.

Frequently Asked Questions about zod

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

FAQPage Schema
How do I validate incoming API request bodies using Zod in TypeScript?

To validate API request bodies with Zod in TypeScript, define an object schema and apply `safeParse()` to the incoming payload, catching invalid data early and returning clear error messages to the client.

What is the best way to handle schema validation errors for user-friendly display?

Handling schema validation errors for user-friendly display involves using Zod's custom messages, internationalization strategies, and formatting the returned error maps to provide clear feedback to the client.

How do I infer TypeScript types directly from my Zod schema definitions?

You can infer TypeScript types directly from Zod schema definitions using built-in type inference features, ensuring your static types automatically match your runtime validation rules for robust data integrity.

Can I perform async validation with Zod at system boundaries?

Yes, you can perform async validation with Zod at system boundaries by utilizing the parsing guidelines to ensure all incoming data is thoroughly checked before processing, maintaining type safety.

Why should I avoid using z.any() when defining TypeScript schemas?

You should avoid using `z.any()` when defining TypeScript schemas because it bypasses type safety and data validation rules, defeating the purpose of using Zod to prevent runtime errors and ensure data integrity.

Does Zod support schema composition and custom refinements for complex validation?

Yes, Zod supports schema composition and custom refinements, allowing developers to build complex validation logic by combining multiple schemas and adding custom constraints to ensure robust data handling.
