date-fns / babel-plugin-date-fns Goto Github PK

For example is it possible to do this:

import { format as dateFnsFormat } from "date-fns";

dateFnsFormat(new Date(), "yyyy-MM-dd");

In some cases I have same name functions that conflict with "date-fns", so I think it perhaps would be better to support this feature.

Imports of locale aren't working. This:
import en from "date-fns/locale/en"
causes an error:
Error: Cannot find module 'date-fns/locale'.

Should I do the import otherwise, or is it a bug in the plugin? Thanks a lot!

It looks like it does not work for getISODay

Plugin is pretty slow now, (in my case build time increased from 25 to 45 seconds).

Is it possible to speed up plugin at all?

Hi there - it seems like this is doing a module lookup right now to determine the import filename. What about doing it programmatically, seeing as date-fns's filenames follow a pattern:

function importNameToFilename(importName) {
  return 'date-fns/' + importName.replace(/([A-Z])/, '_$1').toLowerCase();
}

importNameToFilename('startOfYear') // "date-fns/start_of_year"
importNameToFilename('differenceInCalendarDays') // "date-fns/difference_in_calendar_days"

It seems like this would address #2.

Transform:

import dt from 'date-fns';

const x = dt.addHours(new Date(), 1); 
const y = dt.format(y, 'MM/DD/YYYY');

to

import addHours from 'date-fns/add_hours';
import format from 'date-fns/format';

const x = addHours(new Date(), 1); 
const y = format(y, 'MM/DD/YYYY')

Hello,

We rely on this babel plugin to help with bundling only application code that we use. Does it support the somewhat recent date-fns 2.x release?

Thanks!
David
