Modal Imperative API Guide

Use createModal from @lobehub/ui for imperative modal dialogs.

Why Imperative?

Mode	Characteristics	Recommended
Declarative	Need open state, render <Modal />	❌
Imperative	Call function directly, no state	✅

File Structure

features/
└── MyFeatureModal/
    ├── index.tsx           # Export createXxxModal
    └── MyFeatureContent.tsx # Modal content

Implementation

1. Content Component (MyFeatureContent.tsx)

'use client';

import { useModalContext } from '@lobehub/ui';
import { useTranslation } from 'react-i18next';

export const MyFeatureContent = () => {
  const { t } = useTranslation('namespace');
  const { close } = useModalContext(); // Optional: get close method

  return <div>{/* Modal content */}</div>;
};

2. Export createModal (index.tsx)

'use client';

import { createModal } from '@lobehub/ui';
import { t } from 'i18next'; // Note: use i18next, not react-i18next

import { MyFeatureContent } from './MyFeatureContent';

export const createMyFeatureModal = () =>
  createModal({
    allowFullscreen: true,
    children: <MyFeatureContent />,
    destroyOnHidden: false,
    footer: null,
    styles: { body: { overflow: 'hidden', padding: 0 } },
    title: t('myFeature.title', { ns: 'setting' }),
    width: 'min(80%, 800px)',
  });

3. Usage

import { createMyFeatureModal } from '@/features/MyFeatureModal';

const handleOpen = useCallback(() => {
  createMyFeatureModal();
}, []);

return <Button onClick={handleOpen}>Open</Button>;

i18n Handling

• Content component: useTranslation hook (React context)
• createModal params: import { t } from 'i18next' (non-hook, imperative)

useModalContext Hook

const { close, setCanDismissByClickOutside } = useModalContext();

Common Config

Property	Type	Description
allowFullscreen	boolean	Allow fullscreen mode
destroyOnHidden	boolean	Destroy content on close
footer	ReactNode | null	Footer content
width	string | number	Modal width
