Form with Validation

What you'll build

A registration form with professional validation using React, react-hook-form and zod. It will have name, email, password and confirmation fields with real-time validation. Users will see clear error messages instantly, and the submit button will only activate when everything is valid. You'll learn the industry-standard pattern for handling forms.

Types of validation

Always validate on server. Client is just UX.

Step 1: Ask an AI for the form

I need a registration form in React with:
- Fields: name, email, password, confirm password
- Real-time validation
- Clear error messages
- Button disabled until valid
- Tailwind CSS styling
- Use react-hook-form and zod

Give me the complete code.

Recommended libraries

Example with zod

import { z } from 'zod'

const schema = z.object({
  email: z.string().email('Invalid email'),
  password: z.string().min(8, 'Minimum 8 characters'),
  confirmPassword: z.string()
}).refine(data => data.password === data.confirmPassword, {
  message: 'Passwords do not match',
  path: ['confirmPassword']
})
