date-io

Abstraction over common JavaScript date management libraries.

npm package codecov typescript travis lerna code style: prettier

The project exposes an abstraction interface over luxon, date-fns v2, dayjs and moment. It allows you to build any UI date or time components, while utilizing the same date management library in use within your user's project.

It simplifies timezone management, allows your code to return the exact same type that your user expects and works with specific calendar systems (e.g. Jalali calendar)

Projects

| Library | Downloads | | ----------------- | ----------------------------------------------------------------------------------------------------------------------: | | @date-io/date-fns | npm download | | @date-io/moment | npm download | | @date-io/luxon | npm download | | @date-io/dayjs | npm download | | @date-io/jalaali | npm download | | @date-io/hijri | npm download |

Usage example

import LuxonAdapter from "@date-io/luxon";
import DateFnsAdapter from "@date-io/date-fns";

const dateFns = new DateFnsAdapter(); const luxon = new LuxonAdapter({ locale: "fr" }); // pass french locale

const initialLuxonDate = luxon.date("2018-10-28T11:44:00.000Z"); const initialDateFnsDate = dateFns.date("2018-10-28T11:44:00.000Z");

const updatedLuxonDate = luxon.addDays(initialLuxonDate, 2); const updatedDateFnsDate = dateFns.addDays(initialDateFnsDate, 2);

luxon.format(updatedLuxonDate, "fullDateTime24h"); // "2018, octobre 30 11:44" dateFns.format(updatedLuxonDate, "fullDateTime24h"); // "2018, October 30th 11:44"

Interface

The implemented interface. If you cannot find the method you require, please let us know, and we will add it!

Localized output will of course vary based on the locale and date library used. Inline examples here are based on using

moment
with the
en-US
locale.
export interface DateIOFormats {
  /** Localized full date @example "Jan 1, 2019" */
  fullDate: TLibFormatToken;
