Locally it's working fine, it seems somewhere in the build step things may be going wrong. Is anyone able to look into this?

[johannrp27]

I just have downloaded the repo to play locally: yarn, yarn build and lastly yarn start. Still not working.

When I run this locally I get the same format error. Looks like for this import:

import { format, longFormatters } from "date-fns/format";

ends up now with format being undefined. Looks like date-fns just got updated so I'm guessing it's from that. Probably some breaking change in 4.0 that isn't handled.

@BruceHubbard Nice find, here's the PR that upgraded date-fns: #5102

[martijnrusschen]

@BruceHubbard what happens if you change this to import { format, longFormatters } from "date-fns"; Looking at the date-fns readme that's how they do the import.

How come that update got there? If the diff between v7.3 and v7.4 was just a minor of date-fns

[martijnrusschen]

The docs site is running from the master version of the Datepicker. So it's slightly ahead of the v7.4 version.

[johannrp27]

Nice, I just downgrade date-fns from v4 to v3 and everything is working now, so that's the issue.
As @BruceHubbard said it's a good clue. I did try to find every format and replace it with the import suggested but still not working. I'll keep searching

[martijnrusschen]

@johannrp27 ok thank you! What I can do:

1. revert the upgrade to bring back the site
2. once you've found the fix, you can include the upgrade in the PR

[martijnrusschen]

Revert is merged, https://reactdatepicker.com is back alive! Now, let's figure out how we can make this upgrade work :)

[BruceHubbard]

Thanks Martjin for the quick fix!
