React Hook Form

Overview

React Hook Form is a performant form library that minimizes re-renders. Unlike controlled components (which re-render on every keystroke), RHF uses uncontrolled inputs and only re-renders when necessary. Integrates with Zod for schema validation.

Instructions

Step 1: Basic Form with Zod

npm install react-hook-form @hookform/resolvers zod

// components/SignupForm.tsx — Form with Zod validation
import { useForm } from 'react-hook-form'
import { zodResolver } from '@hookform/resolvers/zod'
import { z } from 'zod'
