What changed, and why?

upgrades JQuery to 4.x
removes (seemingly) unused bootstrap-select dependency. The latest release was more than 4 years ago, and when I went to see how to make it work with JQuery 4.x, I realized we didn't seem to be using it
removes a console.log from a JS test

Screenshots please :)

I recorded a short screen video from my local setup with this branch:

CASA.JQuery.branc.mov

I also tested the forms by entering/selecting different dates and other fields and didn't notice anything broken by removing bootstrap-select but I am fairly new to the app, so let me know if I missed anything.

I will check CI errors tomorrow. Cannot reproduce them locally.

In the release notes,

jQuery source migrated to ES modules

It was a special day when the jQuery source on the main branch was migrated from AMD to ES modules. The jQuery source has always been published with jQuery releases on npm and GitHub, but could not be imported directly as modules without RequireJS, which was jQuery’s build tool of choice. We have since switched to Rollup for packaging jQuery and we do run all tests on the ES modules separately. This makes jQuery compatible with modern build tools, development workflows, and browsers through the use of <script type=module>.

We have jquery installed via node and it's only been accessible via a hack.
Can you undo the hack and use the standard imports?

The hacked way includes imports like

import './jQueryGlobalizer.js'
/* global $ */
/* global window */

This dependency is incompatible with JQuery 4.x. After searching for how it's used in the app, it looks like this dependency isn't being used and can be removed.

stefannibrasil · 2026-02-04T23:14:30Z

Thanks for the context @FireLemons I am working on that.

With JQuery 4, we can use standard imports instead of this globalizer.

This seems to not be necessary anymore but I need to test it. I tried importing it with require and import but it returns a `$ is not defined`.

stefannibrasil · 2026-02-05T03:56:24Z

@FireLemons what do you think of creating a follow up task for changing the import hacks? I tried doing that but I think it would be best to separate the upgrade from other changes.

compwron · 2026-02-05T17:46:21Z

This is very cool and if we can get the build green I would love to merge it :)

Removing the requirement for tooltip.js means that tooltips with data-toggle="tooltip" will no longer be automatically initialized. This file initialized all tooltips on page load. While dashboard.js still manually initializes tooltips in specific callbacks, other parts of the application that use data-toggle="tooltip" (such as app/views/case_contacts/form/details.html.erb line 285) will not have their tooltips initialized unless this functionality is restored. Consider either keeping the tooltip.js file requirement or ensuring tooltip initialization is handled elsewhere in the application (e.g., in application.js or through a Stimulus controller).

Missing semicolons at the end of these statements. While JavaScript's automatic semicolon insertion will handle this, it's inconsistent with the coding style in the rest of the codebase where semicolons are used. For consistency, these lines should end with semicolons to match lines 13, 15-18, etc.

Critical functionality was removed from this file without replacement. The removed code block (between the turbo:load handler and this export statement) contained click handler registration for .followup-button elements that called displayFollowupAlert(). Without this handler, the "Make Reminder" buttons throughout the application (e.g., in app/views/case_contacts/_followup.html.erb) will not work. The displayFollowupAlert function still exists in this file but is now unused. System tests at spec/system/case_contacts/followups/create_spec.rb will fail. Either restore the click handler registration or implement this functionality through a Stimulus controller.

Suggested change

// Register click handler for "Make Reminder" buttons

$(document).on('click', '.followup-button', displayFollowupAlert)

hi @FireLemons and @compwron I would love to get this to the end but I am not there yet.

bootstrap-select is not compatible with jQuery 4.x. I tried a bunch of things but removing that dependency breaks the search/select on reports, and other forms using select2. It looks like we would need to swap bootstrap-select to something else first. The library itself hasn't been updated in 4 years, which wouldn't be a bad thing.

That said, if you have any other approaches that I am not seeing, let me know. I will take a break from this in the meantime to see if I can think of something else.

stefannibrasil · 2026-02-09T23:25:30Z

I am going to close this for now and add the findings to the issue. I will join an office hour session at the end of the month once I am free on Tuesday evenings.
