validation

Overview

Standard Schema helpers for consistent validation and error handling across Zod, Valibot, ArkType, and others.

When to Use

• Validating inputs or API payloads with Standard Schema-compatible schemas
• Normalizing sync and async validation paths
• Handling a single ValidationError type across schema libraries

When Not to Use

• You only need simple, ad-hoc checks without schema validation

Quick Reference

• Guard: isStandardSchema
• Validate: standardValidate
• Sync only: createSyncStandardValidator
• Error: ValidationError

Inputs to Request

• Schema library in use (Zod, Valibot, ArkType)
• Throwing vs non-throwing validation
• Desired error shape and handling
