[December 26, 2025] - Session: Root Folder Fix - TASK COMPLETE! 🎉

Summary

Fixed the unnamed root folder issue that was preventing top-level components from being immediately visible. The ComponentsPanel React migration is now 100% COMPLETE and ready for production use!

Issue Fixed

Problem:

• Unnamed folder with caret appeared at top of components list
• Users had to click the unnamed folder to reveal "App" and other top-level components
• Root folder was rendering as a visible FolderItem instead of being transparent

Root Cause: The convertFolderToTreeNodes() function was creating FolderItem nodes for ALL folders, including the root folder with name: ''. This caused the root to render as a clickable folder item instead of just showing its contents directly.

Solution: Modified convertFolderToTreeNodes() to skip rendering folders with empty names (the root folder). When encountering the root, we now spread its children directly into the tree instead of wrapping them in a folder node.

Files Modified

packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts

• Added check in convertFolderToTreeNodes() to skip empty-named folders
• Root folder now transparent - children render directly at top level
• "App" and other top-level components now immediately visible on app load

// Added this logic:
sortedChildren.forEach((childFolder) => {
  // Skip root folder (empty name) from rendering as a folder item
  // The root should be transparent - just show its contents directly
  if (childFolder.name === '') {
    nodes.push(...convertFolderToTreeNodes(childFolder));
    return;
  }
  // ... rest of folder rendering
});

What Works Now

Before Fix:

▶ (unnamed folder)  ← Bad! User had to click this
  ☐ App
  ☐ MyComponent
  ☐ Folder1

After Fix:

☐ App          ← Immediately visible!
☐ MyComponent  ← Immediately visible!
☐ Folder1      ← Named folders work normally
  ☐ Child1

Complete Feature List (All Working ✅)

• ✅ Full React implementation with hooks
• ✅ Tree rendering with folders/components
• ✅ Expand/collapse folders
• ✅ Component selection and navigation
• ✅ Context menus (add, rename, delete, duplicate)
• ✅ Drag-drop for organizing components
• ✅ Inline rename with validation
• ✅ Home component indicator
• ✅ Component type icons (page, cloud function, visual)
• ✅ Direct ProjectModel subscription (event updates working!)
• ✅ Root folder transparent (components visible by default)
• ✅ No unnamed folder UI issue
• ✅ Zero jQuery dependencies
• ✅ Proper TypeScript typing throughout

Testing Notes

Manual Testing:

1. ✅ Open editor and click Components sidebar icon
2. ✅ "App" component is immediately visible (no unnamed folder)
3. ✅ Top-level components display without requiring expansion
4. ✅ Named folders still have carets and expand/collapse properly
5. ✅ All context menu actions work correctly
6. ✅ Drag-drop still functional
7. ✅ Rename functionality working
8. ✅ Component navigation works

Status Update

Previous Status: 🚫 BLOCKED (85% complete, caching issues)
Current Status: ✅ COMPLETE (100% complete, all features working!)

The previous caching issue was resolved by changes in another task (sidebar system updates). The only remaining issue was the unnamed root folder, which is now fixed.

Technical Notes

• The root folder has name: '' and path: '/' by design
• It serves as the container for the tree structure
• It should never be rendered as a visible UI element
• The fix ensures it acts as a transparent container
• All children render directly at the root level of the tree

Code Quality

• ✅ No jQuery dependencies
• ✅ No TSFixme types
• ✅ Proper TypeScript interfaces
• ✅ JSDoc comments on functions
• ✅ Clean separation of concerns
• ✅ Follows React best practices
• ✅ Uses proven direct subscription pattern from UseRoutes.ts

Migration Complete!

This completes the ComponentsPanel React migration. The panel is now:

• Fully modernized with React hooks
• Free of legacy jQuery/underscore.js code
• Ready for future enhancements (TASK-004 badges/filters)
• A reference implementation for other panel migrations

[December 22, 2025] - Previous Sessions Summary

What Was Completed Previously

Phase 1-4: Foundation & Core Features (85% complete)

• ✅ React component structure created
• ✅ Tree rendering implemented
• ✅ Context menus working
• ✅ Drag & drop functional
• ✅ Inline rename implemented

Phase 5: Backend Integration

• ✅ Component rename backend works perfectly
• ✅ Files renamed on disk
• ✅ Project state updates correctly
• ✅ Changes persisted

Previous Blocker:

• ❌ Webpack 5 caching prevented testing UI updates
• ❌ useEventListener hook useEffect never executed
• ❌ UI didn't receive ProjectModel events

Resolution: The caching issue was resolved by infrastructure changes in another task. The direct subscription pattern from UseRoutes.ts is now working correctly in the ComponentsPanel.
