@zod-to-form/react

Runtime React renderer for Zod v4 schemas.

@zod-to-form/react integrates @zod-to-form/core with React Hook Form and renders schema-driven forms using ZodForm and useZodForm.

Installation

pnpm add @zod-to-form/react @zod-to-form/core zod react react-hook-form @hookform/resolvers

Requirements

• React 18+ (React 19 supported)
• React Hook Form 7+
• Zod v4

Quick Start

import { z } from 'zod';
import { ZodForm } from '@zod-to-form/react';

const userSchema = z.object({
  name: z.string().min(1),
  email: z.string().email(),
  subscribe: z.boolean().default(false)
});

export function UserForm() {
  return (
    <ZodForm
      schema={userSchema}
      mode='onSubmit'
      onSubmit={(data) => {
        console.log('submitted', data);
      }}
    >
      <button type='submit'>Save</button>
    </ZodForm>
  );
}

API

ZodForm

Props:

• schema: Zod object schema (required)
• onSubmit: submit handler with parsed schema output
• onValueChange: called with parsed output on valid field updates
• mode: 'onSubmit' | 'onChange' | 'onBlur'
• defaultValues: partial initial values
• components: partial override map for default components
• componentConfig: runtime component mapping/field overrides
• formRegistry: metadata registry from @zod-to-form/core
• processors: custom/override processors from @zod-to-form/core
• className: class passed to <form>
• children: rendered inside the <form> (typically actions)

useZodForm

Returns:

• form: React Hook Form instance
• fields: walked FormField[] descriptors from schema

import { z } from 'zod';
import { useZodForm } from '@zod-to-form/react';

const schema = z.object({ title: z.string().min(1) });

export function Example() {
  const { form, fields } = useZodForm(schema, {
    mode: 'onChange',
    onValueChange: (values) => {
      console.log(values);
    }
  });

  return <pre>{JSON.stringify({ fieldCount: fields.length, dirty: form.formState.isDirty })}</pre>;
}

Components

defaultComponentMap

Built-in default component map used by ZodForm.

shadcnComponentMap

Shadcn-oriented component map export.

Runtime Component Config

Use componentConfig to map specific field paths to custom components and apply per-component overrides at runtime.

import { ZodForm } from '@zod-to-form/react';
import type { RuntimeComponentConfig } from '@zod-to-form/react';

const componentConfig: RuntimeComponentConfig = {
  components: {
    source: '@/components/form-components',
    overrides: {
      TextareaInput: { controlled: false },
    },
  },
  fields: {
    'profile.bio': {
      component: 'TextareaInput',
      props: { rows: 6 }
    }
  }
};

// <ZodForm schema={schema} componentConfig={componentConfig} />

Accessibility

• Uses native form semantics (<form>, labels, fieldsets/legends where applicable)
• Supports error propagation from React Hook Form state into rendered fields
• Includes accessibility-focused integration tests in this package
