Implement Phase 2 Interactive Features: Session Details Page and Real-Time Updates via SSE #50

Copilot · 2025-10-22T14:47:37Z

Phase 2: Interactive Features Implementation

Continuing implementation of Phase 2 features from PR #49 NEXT_STEPS.md

✅ Completed Features

Phase 2.1: Session Details Page (Complete)

/sessions/[id]/page.tsx - Complete session view with header, metrics, and timeline
/api/sessions/[id]/route.ts - Session details API endpoint
/api/sessions/[id]/events/route.ts - Session events API with filtering
Session detail components (header, metrics, event timeline)

Phase 2.2: Real-Time Updates via SSE (Complete)

/api/events/stream - SSE endpoint with persistent connections
EventBroadcaster - Singleton for server-side event broadcasting
useRealtimeEvents hook - Client-side SSE consumer with auto-reconnection
LiveDashboardStats - Real-time dashboard with connection status indicator

Phase 2.3: Multi-Project Support ✅ (Complete)

📊 Implementation Details

Multi-Project Support Features:

"All Projects" View: When no project is selected, APIs query across all projects
Individual Project View: When a project is selected, only data for that project is shown
URL Persistence: Selected project is stored in URL query parameter (?projectId=123)
Component Integration: All dashboard and sessions components respect the project filter
Seamless Project Switching: Changing projects updates all data in real-time

Bug Fixes:

Fixed infinite re-render loop caused by state updates in ProjectSelector
Changed from managing selectedProject in state to reading directly from searchParams
This prevents the component from re-rendering on every URL change

API Route Updates:
All routes now accept an optional projectId query parameter:

GET /api/dashboard/stats?projectId=1 - Dashboard metrics for specific project
GET /api/dashboard/activity?projectId=1 - Recent activity for specific project
GET /api/sessions?projectId=1 - Sessions for specific project
If projectId is omitted, data is aggregated across all projects

Project Selector Component:

Fetches projects from /api/projects endpoint
Displays "All Projects" option by default
Updates URL with selected project
Shows loading state while fetching projects
Hides if no projects exist
No longer causes infinite re-renders

🎨 UI Changes

The dashboard and sessions pages now display a project selector dropdown in the top right of the header. Users can:

Select "All Projects" to see aggregated data
Select a specific project to filter to that project's data
The selection persists in the URL for bookmarking and sharing

🏗️ Technical Architecture

User selects project in dropdown
  ↓
ProjectSelector updates URL (?projectId=123)
  ↓
Page re-renders with new searchParams
  ↓
Server components fetch data with projectId filter
  ↓
API routes query database with projectId filter
  ↓
Services return filtered data
  ↓
UI displays project-specific data

✅ Build Status

All packages build successfully
No TypeScript errors
All routes properly marked as dynamic (expected for searchParams)
Backward compatible - APIs work without projectId param
No infinite re-render issues

📝 Files Changed

New Files (1):

apps/web/components/agent-observability/project-selector.tsx - Project selector component

Modified Files (10):

apps/web/app/api/dashboard/stats/route.ts - Added projectId parameter support

apps/web/components/agent-observability/sessions/sessions-list.tsx - Accept and use projectId
apps/web/components/agent-observability/project-selector.tsx - Fixed infinite re-render bug

🎯 Phase 2 Complete!

All three sub-phases of Phase 2 are now implemented and tested:

✅ Phase 2.1: Session Details Page
✅ Phase 2.2: Real-Time Updates via SSE
✅ Phase 2.3: Multi-Project Support

Total Changes in Phase 2:

15 new files created
10 files modified
1,500+ lines of code added
3 API endpoints for session details
1 SSE endpoint for real-time updates
3 API routes updated for multi-project support
1 project selector component
All builds passing with no errors

Next Steps:
Continue with Phase 3 (Enhanced Filtering & Search) or Phase 4 (Analytics & Insights) as needed.
