# Vector Inspector Feature - Implementation Summary

## Overview
Successfully implemented a Vector Inspector feature for the RvLite dashboard that allows users to view detailed information about vectors by clicking on vector IDs or the "View Details" button.

## Changes Made to `/workspaces/ruvector/crates/rvlite/examples/dashboard/src/App.tsx`

### 1. Imports Added

**Line 90** - Added `VectorEntry` type:
```typescript
import useRvLite, { type SearchResult, type CypherResult, type SparqlResult, type SqlResult, type VectorEntry } from './hooks/useRvLite';
```

**Line 74** - Added `Eye` icon:
```typescript
import {
  // ... other icons
  ChevronRight,
  Eye,  // NEW
} from 'lucide-react';
```

### 2. useRvLite Hook Enhancement

**Line ~465** - Added `getVector` function to destructuring:
```typescript
const {
  isReady,
  isLoading,
  error: rvliteError,
  stats,
  insertVector,
  insertVectorWithId,
  searchVectors,
  searchVectorsWithFilter,
  getVector,  // NEW
  deleteVector,
  // ... rest
} = useRvLite(128, 'cosine');
```

### 3. State Management

**Line ~528** - Added modal disclosure:
```typescript
const { isOpen: isVectorDetailOpen, onOpen: onVectorDetailOpen, onClose: onVectorDetailClose } = useDisclosure();
```

**Lines ~539-540** - Added state variables:
```typescript
const [selectedVectorId, setSelectedVectorId] = useState<string | null>(null);
const [selectedVectorData, setSelectedVectorData] = useState<VectorEntry | null>(null);
```

### 4. Handler Function

**Lines ~612-627** - Added `handleViewVector` function:
```typescript
const handleViewVector = useCallback((id: string) => {
  try {
    const vectorData = getVector(id);
    if (vectorData) {
      setSelectedVectorId(id);
      setSelectedVectorData(vectorData);
      onVectorDetailOpen();
      addLog('info', `Viewing vector: ${id}`);
    } else {
      addLog('error', `Vector not found: ${id}`);
    }
  } catch (err) {
    addLog('error', `Failed to get vector: ${getErrorMessage(err)}`);
  }
}, [getVector, setSelectedVectorId, setSelectedVectorData, onVectorDetailOpen, addLog]);
```

### 5. Table Modifications

**Lines ~1378-1386** - Made Vector ID clickable:
```typescript
<TableCell>
  <div
    className="flex items-center gap-2 cursor-pointer hover:text-primary transition-colors"
    onClick={() => handleViewVector(vector.id)}
  >
    <FileJson className="w-4 h-4 text-primary" />
    <span className="font-mono text-sm">{vector.id}</span>
  </div>
</TableCell>
```

**Lines ~1399-1408** - Updated View Details button:
```typescript
<Tooltip content="View Details">
  <Button
    isIconOnly
    size="sm"
    variant="light"
    onPress={() => handleViewVector(vector.id)}
  >
    <Eye className="w-4 h-4" />
  </Button>
</Tooltip>
```

### 6. Vector Detail Modal

**Lines ~2904-3040** - Added complete Vector Inspector Modal with:

- **Header**: Shows "Vector Inspector" title with Eye icon and vector ID chip
- **Vector ID Section**: Displays ID in a copyable Snippet component with Hash icon
- **Dimensions Section**: Shows vector dimensions with Layers icon
- **Embedding Values**: Displays vector array values (first 20 if > 20 total) with copy button
- **Metadata Section**: Shows formatted JSON metadata with copy button
- **Error State**: Displays message when vector data is not available
- **Styling**: Dark theme matching existing dashboard (bg-gray-900, border-gray-700, etc.)

## Features Implemented

✅ Click on Vector ID in table to view details
✅ Click "View Details" button (Eye icon) to open inspector
✅ Modal displays:
  - Vector ID (copyable)
  - Dimensions count
  - Embedding values (with smart truncation for long arrays)
  - Metadata as formatted JSON (or "No metadata" message)
✅ Copy buttons for:
  - Vector ID
  - Embedding array
  - Metadata JSON
✅ Logging integration (logs when viewing vector, errors)
✅ Dark theme styling consistent with dashboard
✅ Responsive modal (3xl size, scrollable)

## How to Use

1. **View via Table**: Click on any vector ID in the Vectors table
2. **View via Button**: Click the Eye icon button in the Actions column
3. **In Modal**:
   - See all vector details
   - Copy ID, embedding, or metadata using copy buttons
   - Close with the "Close" button or ESC key

## Code Quality

- TypeScript type safety maintained
- Uses existing patterns (useCallback, error handling)
- Follows HeroUI component conventions
- Matches existing dark theme styling
- No breaking changes to existing functionality
- Proper dependency arrays in hooks

## Testing Notes

The implementation is complete and ready for testing. Pre-existing TypeScript errors in the file (related to SQL table browsing features) are unrelated to this Vector Inspector implementation.

## Files Modified

1. `/workspaces/ruvector/crates/rvlite/examples/dashboard/src/App.tsx` - Main implementation

## Dependencies

- Existing HeroUI components (Modal, ModalContent, ModalHeader, ModalBody, Button, Snippet, Chip)
- Existing Lucide icons (Eye, Hash, Layers, Code, FileJson, Copy, AlertCircle)
- useRvLite hook with `getVector` function
- No new dependencies required
