7.5 | 替换 Moment.js |
你可以用自定义日期库(day.js、date-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;
