Minimized es-module-shims + @hotwired/stimulus-loading in Safari

[tomasc]

Upgrading to importmap-rails v0.9.0 results in issues with eager- or lazyLoad of Stimulus controllers (using @hotwired/stimulus-loading).

= javascript_importmap_tags

JS console:

Failed to autoload controller: modulor--view-components--grid--component
Error: Unable to resolve specifier 'controllers/modulor/view_components/grid/component_controller' from http://127.0.0.1:3010/assets/stimulus-loading-685d40a0b68f785d3cdbab1c0f3575320497462e335c4a63b8de40a355d883c0.js
throwUnresolved — es-module-shims.min.source.js:2

I was able to find out that switching to non-minified version of es-module-shims resolves the issue

= javascript_importmap_tags shim: false
= javascript_importmap_shim_tag minimized: false

You don't have a controller called modulor--view-components--grid--component? I can't replicate the problem in a sample app. Could you try to boil this down to a reproducible case? Thanks!

I have a similar problem: https://discuss.hotwired.dev/t/importmap-rails-0-9-0-broke-stimulus/3506

After upgrading to importmap-rails-0.9.0 I get the error that controllers that were found before are not anymore. If I change from:

<%= javascript_importmap_tags %>

To:

<%= javascript_importmap_tags shim: false %>
<%= javascript_importmap_shim_tag minimized: false %>

It seems to work but then I get console errors that say:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (es-module-shims.js-3e1cdc93efd2cfa4a56543627a4e60e31cf90a9336602e161f327d4be5b5e15a.map, line 0)

EDIT:

For me it is the same in every browser, not just safari. The below image is from Firefox:

@dhh I do have that controller — switching to non-minified version of the shims makes everything work fine again (however I also see the JS error about missing .map file as @mhenrixon described above). It seems to me the .min and .map versions of the shims packaged with the 0.9.0 release are somehow corrupted. I will try to find time to investigate more tomorrow.

There was an error with the minified version that was included. Released 0.9.1 with the correction. Should be all good. Thanks for reporting!

Thank you!
