`ConfigProvider` provides a uniform configuration support for components.

## Usage

This component provides a configuration to all React components underneath itself via the [context API](https://facebook.github.io/react/docs/context.html). In the render tree all components will have access to the provided config.

```tsx
import { ConfigProvider } from 'antd';
import React from 'react';

// ...
const Demo: React.FC = () => (
  <ConfigProvider direction="rtl">
    <App />
  </ConfigProvider>
);

export default Demo;
```

### Content Security Policy

Some components use dynamic style to support wave effect. You can config `csp` prop if Content Security Policy (CSP) is enabled:

```tsx
<ConfigProvider csp={{ nonce: 'YourNonceCode' }}>
  <Button>My Button</Button>
</ConfigProvider>
```

## FAQ

#### How to contribute a new language?

#### Date-related components locale is not working?

#### Modal throw error when setting `getPopupContainer`?

Related issue: <https://github.com/ant-design/ant-design/issues/19974>

When you config `getPopupContainer` to parentNode globally, Modal will throw error of `triggerNode is undefined` because it did not have a triggerNode. You can try the [fix](https://github.com/afc163/feedback-antd/commit/3e4d1ad1bc1a38460dc3bf3c56517f737fe7d44a) below.

```diff
 <ConfigProvider
-  getPopupContainer={triggerNode => triggerNode.parentNode}
+  getPopupContainer={node => {
+    if (node) {
+      return node.parentNode;
+    }
+    return document.body;
+  }}
 >
   <App />
 </ConfigProvider>
```

#### Why can't ConfigProvider props (like `prefixCls` and `theme`) affect ReactNode inside `message.info`, `notification.open`, `Modal.confirm`?

antd will dynamic create React instance by `ReactDOM.render` when call message methods. Whose context is different with origin code located context. We recommend `useMessage`, `useNotification` and `useModal` which , the methods came from `message/notification/Modal` has been deprecated in 5.x.

#### Locale is not working with Vite in production mode?

Related issue: [#39045](https://github.com/ant-design/ant-design/issues/39045)

In production mode of Vite, default exports from cjs file should be used like this: `enUS.default`. So you can directly import locale from `es/` directory like `import enUS from 'antd/es/locale/en_US'` to make dev and production have the same behavior.
