Modal Imperative API Guide

Recommended: @lobehub/ui/base-ui

New code should use the base-ui modal stack (headless primitives, not antd Modal):

• createModal, confirmModal, ModalHost from @lobehub/ui/base-ui
• useModalContext from @lobehub/ui/base-ui inside modal content

Body slot: pass content (or children; runtime uses content ?? children).

Global ModalHost (required)

Base-ui createModal renders through a separate host from the root package. The app must mount ModalHost from @lobehub/ui/base-ui once near the root (e.g. next to other global hosts). Without it, createModal calls will not appear.

If the project only mounts ModalHost from @lobehub/ui, add a second lazy ModalHost from @lobehub/ui/base-ui until all imperative modals are migrated.

Why imperative?

Mode	Characteristics	Recommended
Declarative	open state + <Modal />	❌
Imperative	Call createModal(), no local state	✅

File structure

features/
└── MyFeatureModal/
    ├── index.tsx            # export createXxxModal
    └── MyFeatureContent.tsx # modal body

1. Content (MyFeatureContent.tsx)

'use client';

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

export const MyFeatureContent = () => {
  const { t } = useTranslation('namespace');
  const { close } = useModalContext();

  return <div>{/* ... */}</div>;
};

2. createModal (index.tsx)

'use client';

import { createModal } from '@lobehub/ui/base-ui';
import { t } from 'i18next';

import { MyFeatureContent } from './MyFeatureContent';

export const createMyFeatureModal = () =>
  createModal({
    content: <MyFeatureContent />,
    footer: null,
    maskClosable: true,
    styles: {
      content: { 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

• Content: useTranslation in components.
• createModal options: import { t } from 'i18next' where hooks are unavailable.

useModalContext

const { close, setCanDismissByClickOutside } = useModalContext();

Common options (base-ui)

ImperativeModalProps builds on BaseModalProps: title, width, maskClosable, open, onOpenChange, footer, styles / classNames (keys: backdrop, popup, header, title, close, content, …).

Property	Notes
content	Main body (preferred name vs children)
maskClosable	Click outside to dismiss
styles.*	Semantic regions, not antd styles.body

Confirm

import { confirmModal } from '@lobehub/ui/base-ui';

confirmModal({
  title: '…',
  content: '…',
  okText: '…',
  cancelText: '…',
  onOk: async () => {},
});

Legacy: @lobehub/ui (root)

Older call sites use createModal from @lobehub/ui, which is typed as antd Modal props (children, allowFullscreen, getContainer, destroyOnHidden, styles.body, etc.). Prefer migrating new work to @lobehub/ui/base-ui.

Examples (legacy): src/features/SkillStore/index.tsx, src/features/LibraryModal/CreateNew/index.tsx.

Examples

• Base-ui (preferred): follow sections above; ensure base-ui ModalHost is mounted.
• Legacy: src/features/SkillStore/index.tsx, src/features/LibraryModal/CreateNew/index.tsx
