7.5 替换 Moment.js

你可以用自定义日期库(day.jsdate-fns)替换 Moment 以优化打包大小。在这里我们提供了两种方式来实现替换:

自定义组件

第一种方法是使用 generatePicker(或 generateCalendar)辅助创建 Picker 组件。

我们先初始化一个 create-react-app 的 antd demo你可以参考 在 TypeScript 中使用 进行构建,也可以直接从这里开始init antd

DatePicker.tsx

新建 src/components/DatePicker.tsx

编写如下代码:

import { Dayjs } from 'dayjs';
import dayjsGenerateConfig from 'rc-picker/es/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

新建 src/components/TimePicker.tsx

编写如下代码:

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

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

新建 src/components/Calendar.tsx

编写如下代码:

import { Dayjs } from 'dayjs';
import dayjsGenerateConfig from 'rc-picker/es/generate/dayjs';
import generateCalendar from 'antd/es/calendar/generateCalendar';
import 'antd/es/calendar/style';

const Calendar = generateCalendar<Dayjs>(dayjsGenerateConfig);

export default Calendar;

导出自定义组件

新建 src/components/index.tsx

编写如下代码:

export { default as DatePicker } from './DatePicker';
export { default as Calendar } from './Calendar';
export { default as TimePicker } from './TimePicker';

使用自定义组件

修改 src/App.tsx,引入 dayjs 和自定义的组件。

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

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

如果按照上述步骤无法正确运行的话,你可以参考antd4-generate-picker/antd-ts

如果你需要 JavaScript 代码,你可以参考 antd4-generate-picker/antd-demo

如果你熟悉 umi,你可以参考 antd4-use-dayjs-replace-moment

antd-dayjs-webpack-plugin

我们还提供另一种实现方式。使用 antd-dayjs-webpack-plugin 插件,无需对现有代码做任何修改直接替换成 Day.js。请参考 antd-dayjs-webpack-plugin

// webpack-config.js
import AntdDayjsWebpackPlugin from 'antd-dayjs-webpack-plugin';

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

使用 date-fns

date-fns 目前支持和 dayjs 类似的自定义组件方法,区别在于使用的参数类型不同,在 antd 4.5.0 以上版本提供支持。

做一个简单的例子:

DatePicker.tsx

新建 src/components/DatePicker.tsx

编写如下代码:

import dateFnsGenerateConfig from 'rc-picker/es/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;
