This PR resolves the "Cannot assign to read only property 'exports' of object" JavaScript error that was preventing the CodeceptUI application from loading properly.

Problem

The error occurred due to a module system incompatibility:

// languageDetection.js used CommonJS exports
module.exports = {
  detectLanguage,
  getLanguageDisplayName,  
  isMonacoLanguageSupported
};

// ScenarioSource.vue imported using CommonJS require
const { detectLanguage, getLanguageDisplayName } = require('../utils/languageDetection');

When webpack bundled the Vue components, it expected ES modules but encountered CommonJS exports, creating a conflict where the exports object became read-only in the bundled environment.

Solution

Converted the module system to use ES modules consistently:

  1. Updated src/utils/languageDetection.js to use ES module exports:

    export {
      detectLanguage,
      getLanguageDisplayName,
      isMonacoLanguageSupported
    };
  2. Updated src/components/ScenarioSource.vue to use ES import syntax:

    import { detectLanguage, getLanguageDisplayName } from '../utils/languageDetection';
  3. Updated test/language-detection.spec.js to use dynamic ES imports for test compatibility:

    test.before(async () => {
      const module = await import('../src/utils/languageDetection.js');
      detectLanguage = module.detectLanguage;
      getLanguageDisplayName = module.getLanguageDisplayName;
    });

Results

  • ✅ JavaScript module error completely resolved
  • ✅ Application loads successfully without console errors
  • ✅ All 161 tests continue to pass
  • ✅ Language detection functionality works properly
  • ✅ Build process completes without module-related errors
**Before:** Application failed to load with module.exports error ![Error Screenshot](https://github.com/user-attachments/assets/8e5681cc-44bb-4e66-94a0-844eb82d205e)

After: Application loads successfully with full functionality
Success Screenshot

The remaining console errors (ERR_BLOCKED_BY_CLIENT) are unrelated external resource loading issues and don't affect core functionality.

Fixes #574.
