When To Use

Provide reset styles based on .ant-app element.
You could use static methods of message/notification/Modal from useApp without writing contextHolder manually.

Examples

How to use

Basic usage

App provides upstream and downstream method calls through Context, because useApp needs to be used as a subcomponent, we recommend encapsulating App at the top level in the application.

import React from 'react';
import { App } from 'antd';

const MyPage: React.FC = () => {
  const { message, notification, modal } = App.useApp();
  message.success('Good!');
  notification.info({ message: 'Good' });
  modal.warning({ title: 'Good' });
  // ....
  // other message, notification, modal static function
  return <div>Hello word</div>;
};

const MyApp: React.FC = () => (
  <App>
    <MyPage />
  </App>
);

export default MyApp;

Note: App.useApp must be available under App.

Sequence with ConfigProvider

The App component can only use the token in the ConfigProvider, if you need to use the Token, the ConfigProvider and the App component must appear in pairs.

<ConfigProvider theme={{ ... }}>
  <App>
    ...
  </App>
</ConfigProvider>

Embedded usage scenarios (if not necessary, try not to do nesting)

<App>
  <Space>
    ...
    <App>...</App>
  </Space>
</App>

Global scene (redux scene)

// Entry component
import { App } from 'antd';
import type { MessageInstance } from 'antd/es/message/interface';
import type { ModalStaticFunctions } from 'antd/es/modal/confirm';
import type { NotificationInstance } from 'antd/es/notification/interface';

let message: MessageInstance;
let notification: NotificationInstance;
let modal: Omit<ModalStaticFunctions, 'warn'>;

export default () => {
  const staticFunction = App.useApp();
  message = staticFunction.message;
  modal = staticFunction.modal;
  notification = staticFunction.notification;
  return null;
};

export { message, modal, notification };

// sub page
import React from 'react';
import { Button, Space } from 'antd';

import { message } from './store';

export default () => {
  const showMessage = () => {
    message.success('Success!');
  };

  return (
    <Space>
      <Button type="primary" onClick={showMessage}>
        Open message
      </Button>
    </Space>
  );
};

FAQ

CSS Var doesn't work inside `<App component={false}>`

Make sure the App component is a legit React component string, so when you're turning on CSS variables, there's a container to hold the CSS class name.
