`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}

<App />
</ConfigProvider>
