Success Criteria

✅ Passed Requirements

File Loading (from POC-3):

✅ Loads content from valid file paths
✅ Path normalization works correctly
✅ Missing files display user-friendly errors
✅ Invalid prop combinations display errors

Theme Synchronization (from POC-2.2):

Integration:

✅ File loading + theme sync work together
✅ No conflicts between features
✅ Console logs show both features active
✅ Production build succeeds
✅ All 6 Playwright tests pass

Test Results

Playwright Tests:

text

✓ POC-4: Comprehensive (6 tests, ~15s)
  ✓ loads files and displays diff correctly
  ✓ synchronizes theme with VitePress toggle
  ✓ handles multiple rapid theme toggles
  ✓ displays error for missing file
  ✓ displays error for invalid props
  ✓ validates console logs for theme and file loading

Build Validation:

Clean build: ✅ Success
Production build time: ~24s
Preview server: ✅ Started successfully
Production tests: ✅ All pass

Component Architecture

File: docs/.vitepress/components/MonacoDiff.vue

Key Features:

✅ VitePress content loader for file loading (works with srcExclude)
✅ VitePress theme detection via useData().isDark
✅ Reactive theme synchronization via watch(monacoTheme)
✅ Props: oldFile, newFile, oldContent, newContent, language
✅ Comprehensive error handling and validation
✅ Reactive updates for content, language, and theme changes

Integration Success:

File loading uses VitePress data loader pattern
Theme sync uses VitePress useData() hook
Both features operate independently without conflicts
Single component handles all use cases

Manual Verification Checklist

✅ Test Case 1: Files load, theme switches instantly
✅ Test Case 2: Props-based content, theme switches work
✅ Test Case 3: Missing file shows error
✅ Test Case 4: Invalid props shows error
✅ No console errors during normal operation
✅ No console errors during theme toggling
✅ Production build works correctly

Conclusion

POC-4 successfully validates that file loading and theme synchronization can be combined in a single production-ready component without conflicts. The VitePress content loader pattern and theme detection integrate seamlessly.

Overall POC Status: ✅ PASS - Production-ready comprehensive component validated.

Next Steps: Deploy MonacoDiff.vue as the canonical component for blog posts and documentation.
