🎯 What Was Built

ClusterFolderView Component

Purpose: Provides hierarchical folder navigation within cluster pages using the "Virtual Root with Library Folders" design.

Key Features:

1. Virtual Root Display

Renders library cards for all libraries in the cluster
Statistics per library:
- Total item count
- Video/Photo/Text counts
- Total storage size
Cluster color theming on library cards
Click navigation into each library

Reuses VirtualizedFolderGrid component
Breadcrumb system: Cluster Name > Library > Folder1 > Folder2
Back button: Returns to parent folder or virtual root
State management: Tracks current path and navigation state

Navigation Flow:

Virtual Root (library cards)
    ↓ Click Library
Library Root (folders + files)
    ↓ Click Folder
Subfolder (nested contents)
    ↓ Click Media File
Media Viewer (video/photo/text player)

Format: Cluster Name (colored) > Library > Folder > Subfolder

Examples:

Virtual Root: (no breadcrumbs)
Library Root: My Movies > /mnt/movies/action
Subfolder: My Movies > /mnt/movies/action > 2023 > January

Features:

First breadcrumb (cluster name) uses cluster color
Clickable breadcrumbs for quick navigation
Home icon on cluster name
Current location highlighted

4. State Management

const [currentPath, setCurrentPath] = useState<string | null>(null);
const [isVirtualRoot, setIsVirtualRoot] = useState(true);
const [virtualRootLibraries, setVirtualRootLibraries] = useState<Library[]>([]);
const [breadcrumbs, setBreadcrumbs] = useState<BreadcrumbItem[]>([]);

States:

null path = virtual root
Non-null path = folder view
isVirtualRoot flag controls rendering mode

VirtualizedFolderGrid Enhancement

Changes Made:

1. New Props

interface VirtualizedFolderGridProps {
  // ... existing props
  clusterId?: number;        // NEW: For cluster folder view
  clusterApiMode?: boolean;  // NEW: Use cluster API endpoint
}

2. Conditional API Endpoint

if (clusterApiMode && clusterId) {
  // Use cluster API: /api/clusters/[id]/folders?path=...
  res = await fetch(`/api/clusters/${clusterId}/folders?path=${path}`);
  data = await res.json();
  setItems(data.items); // Cluster API returns { items: [...] }
} else {
  // Use regular API: /api/files?path=...
  res = await fetch(`/api/files?path=${path}`);
  data = await res.json();
  setItems(data); // Regular API returns array directly
}

3. Backward Compatibility

Default behavior unchanged: clusterApiMode = false
Existing Folder Viewer works: No modifications needed
New cluster mode: Activated only when clusterApiMode={true}

Cluster Page Integration

Changes Made:

1. Import ClusterFolderView

import ClusterFolderView from '@/components/cluster-folder-view';

2. Update MediaType

type MediaType = 'videos' | 'photos' | 'texts' | 'folders' | 'stats';

3. Add Folders Tab (First Position)

<button
  onClick={() => setActiveTab('folders')}
  className={/* active styles */}
>
  <Folder className="h-4 w-4 inline mr-2" />
  Folders
</button>

4. Set as Default Tab

const [activeTab, setActiveTab] = useState<MediaType>('folders');

5. Add Tab Content

{activeTab === 'folders' && cluster && (
  <ClusterFolderView
    clusterId={clusterId}
    cluster={cluster}
    libraries={libraries}
    onVideoClick={handleVideoClick}
    onPhotoClick={handlePhotoClick}
    onTextClick={handleTextClick}
  />
)}

🎨 User Experience

Scenario 1: Browse Cluster Folders

User opens cluster page → Folders tab active by default
Sees virtual root → 3 library cards with statistics
Clicks library card → Navigates to library root
Breadcrumb shows: My Movies > /mnt/movies/action
Sees folders and files → Mixed display, folders first
Clicks folder → Drills down into subfolder
Breadcrumb updates: My Movies > /mnt/movies/action > 2023
Clicks video → Video player modal opens
Closes player → Returns to same folder view
Clicks cluster name in breadcrumb → Returns to virtual root

Scenario 2: Quick Library Switching

User browsing deep folder: Cluster > Library1 > Folder1 > Folder2
Clicks cluster name in breadcrumb → Returns to virtual root
Sees all libraries → Clicks different library card
Now browsing Library2 → Seamless switch within cluster

Scenario 3: Empty Cluster

Cluster has no libraries assigned
Virtual root shows empty state:
- Folder icon
- "No libraries in this cluster"
- "Add libraries to this cluster in Settings"
User guided to settings page

📊 Technical Highlights

🧪 Testing Checklist

Manual Testing Needed

Virtual root displays library cards correctly
Library statistics are accurate
Clicking library card navigates to library root
Breadcrumbs update correctly
Back button works from all levels
Clicking breadcrumb navigates correctly
Video player opens from folder view
Photo viewer opens from folder view
Text viewer opens from folder view
Empty cluster shows helpful message
Error states display properly
Cluster color theming applied correctly

Edge Cases to Test

Cluster with no libraries
Library with no media
Deep folder nesting (20+ levels)
Very large folders (1000+ items)
Special characters in folder names
Navigation speed with many folders
Tab switching preserves state
