JS Cookie library deprecated in Drupal 10.1, removed in Drupal 11 without replacement

[andybroomfield]

The core/js-cookie asset library is deprecated in Drupal 10.1.0 and will be removed in Drupal 11.0.0. There is no replacement. See https://www.drupal.org/node/3322720

So does this mean we need to declare a dependancy on it directly and ask users to download it to the libraries folder? Or just include a copy.

... or refactor the code to remove the dependency, could be done at the same time as removing the jQuery dependency (#201)

I would probably recommend using vanilla javascript and then switching out cookies in favour of localstorage.

On the 4 Apr 2024, they updated that change record with a solution to switch to a contrib module which is unsurprisingly called JS Cookie. It's maintained by Dave Reid who is prolific.

That js-cookie module just does one thing: get the js-cookie JS from https://github.com/js-cookie/js-cookie so that it can be used in a Drupal site.

I think the simplest thing is to update our .libraries.yml file to fetch that JS file for us and then we don't need to worry about needing the Drupal module.

Thanks to Big Blue Door for sponsoring my time to work on this.

Tthe current plan given we don't use many of the features, just set and read back a cookie, is to try and remove the dependency. @millnut is trying to switch to local storage in #322.
I really would like to avoid having sites load a Javascript file from a CDN.

What's the thinking behind using localStorage instead of a cookie?
