How can I export a plugin from dayjs() in Javascript?

Question

I am using the pluginisToday()to extend the functionality ofdayjs()but I don't know how to export isToday() so I can use it in other files.

import isToday from "dayjs/plugin/isToday";

export dayjs.extend(isToday);

Answer 1

I was able to get it done by creating my own dayjs class:

import dayjs from 'dayjs';
import isSameOrBefore from 'dayjs/plugin/isSameOrBefore';
import isSameOrAfter from 'dayjs/plugin/isSameOrAfter';
import 'dayjs/locale/en';

const appDayjs = dayjs;

appDayjs.extend(isSameOrBefore);
appDayjs.extend(isSameOrAfter);

export { appDayjs }; // OR export default appDayjs

If you are using TypeScript and you want a Dayjs similar type, you can use:

// ...

const appDayjsInstance = appDayjs();
type AppDayjs = typeof appDayjsInstance;

export {
  appDayjs,
  AppDayjs,
}
