Migrating dependencies on Drupal core jQuery UI libraries

jQuery UI libraries are no longer in core, but everything needed is in contrib

jQuery UI libraries are no longer provided by Drupal core.

If your modules/themes depend on a core jQuery UI library (i.e. depend on any library that begins with core/jquery.ui), they must be updated to depend on libraries provided by contrib modules instead. These contrib modules work with Drupal 9.2 and newer in addition to Drupal 10, so you can make this switch on an existing Drupal 9 site.

Use the table below to help you identify which contrib module(s) should be installed, and what the library name should be changed to.

• Find the library/libraries your code uses in the Removed Removed core asset library column,
• Download/require and install the corresponding Replacement contributed module and change the library name and configure your module/theme to depend on them
• Change any use of a Removed core asset library in your codebase to the corresponding Replacement library name

Composer is recommended

If composer is used to add these modules, the correct versions and any necessary dependencies will automatically be installed.

If you're not using composer, be aware of the following

Be sure to install the recommended releases for any of the modules mentioned above. This means the core jquery_ui module must be 1.6 or newer, and all other jQuery UI modules must be version 2.0 or newer.

TLDR: install the corresponding contrib module(s) and change the corresponding library name(s), and that's it

You don't need to add any assets or create libraries yourself. The contrib modules take care of everything other than renaming the libraries your code depends on.
