Available since `5.13.0`.
|
|
|
|
## GetRef
|
|
|
|
Get the `ref` property definition of the component, which is very useful for components that are not directly exposed or child components.
|
|
|
|
```tsx
|
|
import { Select } from 'antd';
|
|
import type { GetRef } from 'antd';
|
|
|
|
type SelectRefType = GetRef<typeof Select>; // BaseSelectRef
|
|
```
|
|
|
|
## GetProps
|
|
|
|
Get the `props` property definition of the component:
|
|
|
|
```tsx
|
|
import { Checkbox } from 'antd';
|
|
import type { GetProps } from 'antd';
|
|
|
|
type CheckboxGroupType = GetProps<typeof Checkbox.Group>;
|
|
```
|
|
|
|
## GetProp
|
|
|
|
Get the single `props` property definition of the component. It has encapsulated `NonNullable`, so you don't have to worry about it being empty:
|
|
|
|
```tsx
|
|
import { Select } from 'antd';
|
|
import type { GetProp, SelectProps } from 'antd';
|
|
|
|
// Both of these can work
|
|
type SelectOptionType1 = GetProp<SelectProps, 'options'>[number];
|
|
type SelectOptionType2 = GetProp<typeof Select, 'options'>[number];
|
|
```
