How do you integrate Zod with React forms for End-to-End Type-Safety?

Short answer

Define a Zod Schema, derive its TypeScript type with z.infer, and connect it to a React form with zodResolver for synchronous validation.

Explanation

Zod provides a declarative way to validate data on both the client and server. Together, zodResolver and React Hook Form automatically validate inputs, display matching messages, and provide accurate TypeScript autocomplete for form types without duplicating type definitions.

Code example

import { z } from 'zod';
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';

const loginSchema = z.object({
  email: z.string().email("Invalid email"),
  password: z.string().min(8, "Password must be at least 8 characters")
});

type LoginFormValues = z.infer<typeof loginSchema>;

function Form() {
  const { register, handleSubmit, formState: { errors } } = useForm<LoginFormValues>({
    resolver: zodResolver(loginSchema)
  });
  // Type-safe usage with automatic validation
}

Common mistakes

• Writing a separate TypeScript interface that duplicates the Zod Schema.
