Table of Contents
Overview
Implement comprehensive form validation including client-side validation, server-side synchronization, and real-time error feedback with TypeScript type safety.
When to Use
- User input validation
- Form submission handling
- Real-time error feedback
- Complex validation rules
- Multi-step forms
Quick Start
Minimal working example:
// types/form.ts
export interface LoginFormData {
email: string;
password: string;
rememberMe: boolean;
}
export interface RegisterFormData {
email: string;
password: string;
confirmPassword: string;
name: string;
terms: boolean;
}
// components/LoginForm.tsx
import { useForm, SubmitHandler } from 'react-hook-form';
import { LoginFormData } from '../types/form';
const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
export const LoginForm: React.FC = () => {
const {
register,
handleSubmit,
// ... (see reference guides for full implementation)
