## How to use DatePicker with a custom date library like dayjs
|
|
|
|
Considering it's bundle size, you might want to replace Moment.js with a different date library of your choice. We provide two ways to customize which date library is used:
|
|
|
|
### Custom component
|
|
|
|
The first way is use `generatePicker` (or `generateCalendar`) helps to create Picker components.
|
|
|
|
First, we initialize an antd demo with `create-react-app`. You can refer to [Use in TypeScript](/docs/react/use-in-typescript), or you can start directly here [init antd](https://github.com/xiaohuoni/antd4-generate-picker/commit/47fec964e36d48bd15760f8f5abcb9655c259aa6)
|
|
|
|
#### DatePicker.tsx
|
|
|
|
Create `src/components/DatePicker.tsx`.
|
|
|
|
For example:
|
|
|
|
```tsx
|
|
import { Dayjs } from 'dayjs';
|
|
import dayjsGenerateConfig from 'rc-picker/lib/generate/dayjs';
|
|
import generatePicker from 'antd/es/date-picker/generatePicker';
|
|
import 'antd/es/date-picker/style/index';
|
|
|
|
const DatePicker = generatePicker<Dayjs>(dayjsGenerateConfig);
|
|
|
|
export default DatePicker;
|
|
```
|
|
|
|
#### TimePicker.tsx
|
|
|
|
Create `src/components/TimePicker.tsx`.
|
|
|
|
For example:
|
|
|
|
```tsx
|
|
import { Dayjs } from 'dayjs';
|
|
import * as React from 'react';
|
|
import DatePicker from './DatePicker';
|
|
import { PickerTimeProps } from 'antd/es/date-picker/generatePicker';
|
|
import { Omit } from 'antd/es/_util/type';
|
|
|
|
export interface TimePickerProps extends Omit<PickerTimeProps<Dayjs>, 'picker'> {}
|
|
|
|
const TimePicker = React.forwardRef<any, TimePickerProps>((props, ref) => {
|
|
return <DatePicker {...props} picker="time" mode={undefined} ref={ref} />;
|
|
});
|
|
|
|
TimePicker.displayName = 'TimePicker';
|
|
|
|
export default TimePicker;
|
|
```
|
|
|
|
#### Calendar.tsx
|
|
|
|
Create `src/components/Calendar.tsx`.
|
|
|
|
For example:
|
|
|
|
```tsx
|
|
import { Dayjs } from 'dayjs';
|
|
import dayjsGenerateConfig from 'rc-picker/lib/generate/dayjs';
|
|
import generateCalendar from 'antd/es/calendar/generateCalendar';
|
|
import 'antd/es/calendar/style';
|
|
|
|
const Calendar = generateCalendar<Dayjs>(dayjsGenerateConfig);
|
|
|
|
export default Calendar;
|
|
```
|
|
|
|
#### Export Custom component
|
|
|
|
Create `src/components/index.tsx`.
|
|
|
|
For example:
|
|
|
|
```tsx
|
|
export { default as DatePicker } from './DatePicker';
|
|
export { default as Calendar } from './Calendar';
|
|
export { default as TimePicker } from './TimePicker';
|
|
```
|
|
|
|
#### Use Custom component
|
|
|
|
Modify `src/App.tsx`,import `dayjs` and custom component.
|
|
|
|
```diff
|
|
- import { DatePicker, Calendar } from 'antd';
|
|
- import format from 'moment';
|
|
|
|
+ import { DatePicker, TimePicker, Calendar } from './components';
|
|
+ import format from 'dayjs';
|
|
```
|
|
|

If the above steps do not work correctly, you can refer to [antd4-generate-picker/antd-ts](https://github.com/xiaohuoni/antd4-generate-picker/tree/master/antd-ts).
|
|
|
|
If you need JavaScript code, you can refer to [antd4-generate-picker/antd-demo](https://github.com/xiaohuoni/antd4-generate-picker/tree/master/antd-demo).
|

|
|
If you use [umi](https://umijs.org/), you can reference [antd4-use-dayjs-replace-moment](https://github.com/xiaohuoni/antd4-use-dayjs-replace-moment).
|
|
|
|
### Webpack plugin
|
|
|
|
We also provide another implementation, which we provide with `antd-dayjs-webpack-plugin`, replacing `momentjs` with `Day.js` directly without changing a line of existing code. More info can be found at [antd-dayjs-webpack-plugin](https://github.com/ant-design/antd-dayjs-webpack-plugin).
