🔧 Backend Integration Required
The following components are ready for backend integration. All include TODO comments marking API integration points:
Admin Panel APIs Needed
// Dashboard GET /admin/metrics GET /admin/system-status // Knowledge Base GET /admin/documents POST /admin/documents/upload DELETE /admin/documents/:id POST /admin/documents/:id/reindex // Analytics GET /admin/analytics?range={7d|30d|90d} // System Health GET /admin/health GET /admin/logs?limit=50
Example Integration
// Before (mock data) setMetrics({ activeSessions: 42, totalConversations: 1247, // ... }); // After (production) const metricsData = await apiClient.get("/admin/metrics"); setMetrics(metricsData);
All components gracefully handle loading states and errors, making backend integration straightforward.
