React Hook Form + Zod Validation: AI Prompt Example

This prompt demonstrates how to wire up React Hook Form with Zod for schema-based validation — all without a build tool. It instructs the AI to generate a fully functional registration form loaded via CDN links, making it instantly runnable in any browser or code sandbox. The form covers common real-world field rules: minimum character lengths, email format checks, numeric age restrictions, and a composite password policy requiring uppercase, lowercase, and digits. Error messages appear inline as users type, and the submit button stays disabled until every field passes validation, directly improving the user experience.

This kind of prompt is ideal for front-end developers who want a clean, copy-paste starting point for client-side validation without setting up a bundler like Vite or Webpack. It also works well as a learning reference for teams adopting TypeScript-friendly validation patterns. To extend it, try adding a confirm-password field with Zod's refine method, swapping the CDN setup for an npm-based project, or replacing the custom styles with a component library like shadcn/ui or Tailwind CSS.
