develop already allows node_modules as an import root (da286cd), but wip/1.3 doesn't yet. On 1.3, the LESS import gate from wintercms/storm#245 applies to every file in the import graph. That blocks modules/system/assets/ui/less/icon.variables.less from importing Font Awesome's variables, so any combiner asset importing modules/backend/assets/less/core/boot.less fails. One example is the Translate plugin's multilingual.less, which breaks php artisan winter:util compile assets with:

Less_Exception_Compiler: variable @fa-var-500px is undefined in file .../modules/system/assets/ui/less/icon.variables.less on line 24

This adds a regression test for an import chain from an asset through an allowed root into node_modules, so the root can't be dropped without a failing test. It also adds a comment explaining why the root is there. The test fails without the node_modules root and passes with it.

Summary by CodeRabbit

• Tests
  • Added coverage verifying that LESS styles can import variables from packages in node_modules and compile the resulting styles correctly. The test checks that imported values appear in the compiled output and that theme styles are included, helping catch issues with this import path. No user-facing behavior changes.

Walkthrough

The change documents that node_modules is an allowed import root for the system UI’s Font Awesome LESS imports. It adds a regression test for LESS compilation through a shared file that imports a file from node_modules. The test checks the compiled output and removes its temporary fixtures.

Estimated code review effort: 2 (Simple) | ~8 minutes

Merge Risk: Minimal · up to c07a3

The change documents the existing import root and adds regression coverage. No merge-blocking risk was identified.

@JonasPardon can you rebase against develop instead of 1.3 and then I'll merge develop into 1.3 after this gets merged?

[JonasPardon]

@LukeTowers Rebased onto develop and retargeted. Develop already allows node_modules (da286cd), so the PR now only adds the regression test and a comment explaining that root. Merging develop into 1.3 will bring the fix over.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Move fixture setup inside the cleanup scope.

makeTempThemeDir() creates the theme before the test calls random_bytes() at line 240. random_bytes() can throw, so the test can exit before finally and leave the theme behind. PHPUnit also converts unhandled filesystem warnings into test errors, so later mkdir() or file_put_contents() failures can leave earlier fixtures behind.

🐛 Suggested fix

             // absent, so a node_modules left behind here would make them run.
