`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.

```jsx
import { ConfigProvider } from 'antd';

// ...

export default () => (
  <ConfigProvider direction="rtl">
    <App />
  </ConfigProvider>
);
```

### Content Security Policy

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

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

## FAQ

#### How to contribute a new language?

See [<Adding new language>](/docs/react/i18n#Adding-newplanguage).

#### Does the locale problem still exist in DatePicker even if ConfigProvider `locale` is used?

Please make sure you set moment locale or that you don't have two different versions of moment.

```js
import 'moment/locale/zh-cn';
moment.locale('zh-cn');
```

#### 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>
