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:

import useRvLite, { type SearchResult, type CypherResult, type SparqlResult, type SqlResult, type VectorEntry } from './hooks/useRvLite';

Line 74 - Added Eye icon:

import {
  // ... other icons
  ChevronRight,
  Eye,  // NEW
} from 'lucide-react';

2. useRvLite Hook Enhancement

Line ~465 - Added getVector function to destructuring:

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:

const { isOpen: isVectorDetailOpen, onOpen: onVectorDetailOpen, onClose: onVectorDetailClose } = useDisclosure();

Lines ~539-540 - Added state variables:

const [selectedVectorId, setSelectedVectorId] = useState<string | null>(null);
const [selectedVectorData, setSelectedVectorData] = useState<VectorEntry | null>(null);

4. Handler Function

Lines ~612-627 - Added handleViewVector function:

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:

<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:

<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
