`ConfigProvider` provides a uniform configuration support for components.

## Usage

This component provides a configuration to all Vue components underneath itself via the [provide / inject](https://vuejs.org/v2/api/#provide-inject), In the render tree all components will have access to the provided config.

```html
<template>
  <a-config-provider :getPopupContainer="getPopupContainer">
    <app />
  </a-config-provider>
</template>
<script>
  export default {
    methods: {
      getPopupContainer(el, dialogContext) {
        if (dialogContext) {
          return dialogContext.getDialogWrap();
        } else {
          return document.body;
        }
      },
    },
  };
</script>
```

### Content Security Policy

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

```html
<a-config-provider :csp="{ nonce: 'YourNonceCode' }">
  <a-button>My Button</a-button>
</a-config-provider>
```

## FAQ

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

Please make sure you set dayjs locale by `dayjs.locale('zh-cn')` or that you don't have two different versions of dayjs.

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

When you config `getPopupContainer` to parentNode globally, Modal will throw error of `triggerNode is undefined` because it did not have a triggerNode.

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