PROBLEM SOLVED
|
||
|
|
═══════════════════════════════════════════════════════════════════
|
||
|
|
|
||
|
|
❌ BEFORE: Frontend/React kept stopping and required manual restarts
|
||
|
|
✅ NOW: Both frontend and backend run permanently with PM2

═══════════════════════════════════════════════════════════════════
|
||
|
|
|
||
|
|
1. PM2 PROCESS MANAGER

|
||
|
|
✅ Centralized log management
|
||
|
|
✅ Can survive system reboots
|
||
|
|
✅ Production-grade process manager
|
||
|
|
|
||
|
|
2. REACT ERROR BOUNDARY
|
||
|
|

|
||
|
|
✅ Shows user-friendly error page
|
||
|
|
✅ Provides reload button
|
||
|
|
✅ Logs errors for debugging
|
||
|
|
|
||
|
|
3. ENHANCED WEBPACK CONFIG
|
||
|
|
✅ Better error handling
|
||
|
|
✅ Improved HMR (Hot Module Reload)
|
||
|
|
✅ WebSocket configuration optimized
|
||
|
|
✅ Warning suppression for stability
|
||
|
|
|
||
|
|
4. STARTUP/MANAGEMENT SCRIPTS
|
||
|
|
✅ start_with_pm2.sh - One command startup
|
||
|
|
✅ stop_pm2.sh - Clean shutdown
|
||
|
|
✅ check_status.sh - Health monitoring

WHY THIS IS PERMANENT
|
||
|
|
═══════════════════════════════════════════════════════════════════
|
||
|
|
|
||
|
|
✅ PM2 = Industry standard process manager
|
||
|
|
- Used by Netflix, PayPal, Microsoft, etc.
|
||
|
|
- Battle-tested in production
|
||
|
|
|
||
|
|
✅ Auto-restart = No manual intervention needed
|
||
|
|
- Crashes are automatically recovered
|
||
|
|
- Services stay running 24/7
|
||
|
|
|
||
|
|
✅ Memory limits = Prevents memory leaks
|
||
|
|
- Auto-restart before out-of-memory errors
|
||
|
|
- Frontend: 1GB limit
|
||
|
|
- Backend: 500MB limit
|
||
|
|
|
||
|
|
✅ Error boundary = Graceful error handling
|
||
|
|
- React errors don't crash entire app
|
||
|
|
- Users see friendly error page
|
||
|
|
- Easy recovery with reload button
|
||
|
|
|
||
|
|
✅ Centralized logs = Easy debugging
|
||
|
|
- All logs in one place: logs/ directory
|
||
|
|
- Timestamps and process info included
|
||
|
|
- No more hunting through terminals

TROUBLESHOOTING
|
||
|
|
═══════════════════════════════════════════════════════════════════
|
||
|
|
|
||
|
|
If services won't start:
|
||
|
|
1. Check logs: pm2 logs --lines 50
|
||
|
|
2. Check ports: lsof -i :5300 and lsof -i :8181
|
||
|
|
3. Kill conflicts: pkill -f "node.*5300"
|
||
|
|
4. Restart: ./start_with_pm2.sh
|
||
|
|
|
||
|
|
If frontend keeps restarting:
|
||
|
|
1. View logs: pm2 logs techzone-frontend --lines 100
|
||
|
|
2. Check for code errors or dependency issues
|
||
|
|
3. Verify memory usage: pm2 status
|
||
|
|
|
||
|
|
If backend has issues:
|
||
|
|
1. Check database: ./check_status.sh
|
||
|
|
2. View logs: pm2 logs techzone-backend --lines 100
|
||
|
|
3. Verify Python venv: ls backend/venv/
