React-datepicker: date-fns does not currently support locale 'ko'

[ahribori]

Expected behavior

<Datepicker locale='ko' />

It should work fine when apply the 'ko' locale through the date-fns@next version.

Actual behavior

An error occurs.

Error: ko locale is currently unavailable. Please check the progress of converting this locale to v2.0.0 in this issue on Github: TBA

There seems to be many locale packages not supported by the date-fns 2.0 alpha version.

Steps to reproduce

1. Install date-fns@next

2. Apply locale configuration.

import Datepicker, { registerLocale } from 'react-datepicker';
import ko from 'date-fns/locale/ko';
registerLocale('ko', ko);

...

render() {
  return <Datepicker locale='ko' />
}

1. An error occurs.

Error: ko locale is currently unavailable. Please check the progress of converting this locale to v2.0.0 in this issue on Github: TBA

+1, any workaround for this? Is there any way to set months/days strings manually? Component's sweet itself, but for my usecase it's useless without proper locale.

Seems that this is an issue that should be logged against date-fns, rather than react-datepicker?
As things stand date-fns v2.x does not yet support Korean - ko is listed in https://github.com/date-fns/date-fns/blob/master/outdatedLocales.json.
Adding support to date-fns for a particular locale is described here:
https://date-fns.org/v2.0.0-alpha.27/docs/I18n#adding-new-language
