# Validator Generator You have TypeScript types but need runtime validation. This generates Zod or Yup schemas from your types. **One command. Zero config. Just works.** ## Quick Start ```bash npx ai-validator ./types/user.ts ``` ## What It Does - Reads TypeScript types - Generates Zod or Yup schemas - Matches your type definitions - Includes helpful error messages ## Usage Examples ```bash # Generate from types file npx ai-validator ./types/user.ts # Yup instead of Zod npx ai-validator ./types/product.ts --library yup ``` ## Best Practices - **Keep types and validators in sync** - regenerate when types change - **Add custom messages** - users need clear errors - **Validate at boundaries** - API inputs, form data - **Test edge cases** - empty strings, nulls, etc. ## When to Use This - Adding validation to existing types - Keeping types and validators synced - Migrating between validation libraries - Learning schema patterns ## Part of the LXGIC Dev Toolkit This is one of 110+ free developer tools built by LXGIC Studios.
