7.5	Use custom date library

By default, Ant Design use Day.js to handle time and date. Day.js is an immutable date-time library alternative to Moment.js with the same API.

You might want to use another date library (Ant design currently supports moment and date-fns). We provide two ways to customize:

Custom component

The first way is to use generatePicker (or generateCalendar) to help create Picker components.

First, we initialize an antd demo with create-react-app. You can refer to Use in TypeScript, or you can start directly here init antd

DatePicker.tsx

Create src/components/DatePicker.tsx.

For example:

import type { Moment } from 'moment';
import momentGenerateConfig from 'rc-picker/lib/generate/moment';
import generatePicker from 'antd/es/date-picker/generatePicker';

const DatePicker = generatePicker<Moment>(momentGenerateConfig);

export default DatePicker;

TimePicker.tsx

Create src/components/TimePicker.tsx.

For example:

import type { Moment } from 'moment';
import * as React from 'react';
import type { PickerTimeProps } from 'antd/es/date-picker/generatePicker';
import DatePicker from './DatePicker';

export interface TimePickerProps extends Omit<PickerTimeProps<Moment>, 'picker'> {}

const TimePicker = React.forwardRef<any, TimePickerProps>((props, ref) => (
  <DatePicker {...props} picker="time" mode={undefined} ref={ref} />
));

TimePicker.displayName = 'TimePicker';

export default TimePicker;

Calendar.tsx

Create src/components/Calendar.tsx.

For example:

import type { Moment } from 'moment';
import momentGenerateConfig from 'rc-picker/lib/generate/moment';
import generateCalendar from 'antd/es/calendar/generateCalendar';

const Calendar = generateCalendar<Moment>(momentGenerateConfig);

export default Calendar;

Export Custom component

Create src/components/index.tsx.

For example:

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 moment and custom component.

- import { DatePicker, Calendar } from 'antd';
- import format from 'dayjs';

+ import { DatePicker, TimePicker, Calendar } from './components';
+ import format from 'moment';

antd-moment-webpack-plugin

We also provide another implementation, which we provide with @ant-design/moment-webpack-plugin, replacing Day.js with moment directly without changing a line of existing code. More info can be found at @ant-design/moment-webpack-plugin.

// webpack-config.js
import AntdMomentWebpackPlugin from '@ant-design/moment-webpack-plugin';

module.exports = {
  // ...
  plugins: [new AntdMomentWebpackPlugin()],
};

Use date-fns

date-fns currently supports custom component methods similar to dayjs. The difference is that the parameter types used are different. Support is provided in antd 4.5.0 and above.

For Example:

DatePicker.tsx

Create src/components/DatePicker.tsx.

Code as follows:

import dateFnsGenerateConfig from 'rc-picker/lib/generate/dateFns';
import generatePicker from 'antd/es/date-picker/generatePicker';
import 'antd/es/date-picker/style/index';

const DatePicker = generatePicker<Date>(dateFnsGenerateConfig);

export default DatePicker;
