## Quick Verification Script

Run this to check everything at once:

```bash
#!/bin/bash
VMID=10130

echo "=== Frontend Deployment Verification ==="
echo ""

echo "1. Container Status:"
pct status $VMID 2>/dev/null || echo "  ❌ Container not found"
echo ""

echo "2. Build Directory:"
pct exec $VMID -- bash -c "test -d /opt/dbis-core/frontend/dist && echo '  ✅ dist/ exists' || echo '  ❌ dist/ missing'" 2>/dev/null || echo "  ❌ Cannot access"
echo ""

echo "3. Index.html:"
pct exec $VMID -- bash -c "test -f /opt/dbis-core/frontend/dist/index.html && echo '  ✅ index.html exists' || echo '  ❌ index.html missing'" 2>/dev/null || echo "  ❌ Cannot check"
echo ""

echo "4. Nginx Status:"
pct exec $VMID -- bash -c "systemctl is-active nginx && echo '  ✅ Nginx running' || echo '  ❌ Nginx not running'" 2>/dev/null || echo "  ❌ Cannot check"
echo ""

echo "5. Nginx Root Directory:"
pct exec $VMID -- bash -c "grep 'root' /etc/nginx/sites-available/dbis-frontend 2>/dev/null | head -1" 2>/dev/null || echo "  ❌ Config not found"
echo ""

echo "6. Build Files:"
JS_COUNT=$(pct exec $VMID -- bash -c "ls -1 /opt/dbis-core/frontend/dist/*.js 2>/dev/null | wc -l" 2>/dev/null || echo "0")
if [ "$JS_COUNT" -gt "0" ]; then
    echo "  ✅ Found $JS_COUNT JavaScript files"
else
    echo "  ❌ No JavaScript files found"

**Fix:** Build the frontend
```bash
pct exec 10130 -- bash -c "cd /opt/dbis-core/frontend && npm run build"
```

### Issue: Nginx not running
**Fix:** Start nginx
```bash
pct exec 10130 -- systemctl start nginx
```

### Issue: Wrong nginx root directory
**Fix:** Update nginx config
```bash
pct exec 10130 -- bash -c "sed -i 's|root.*|root /opt/dbis-core/frontend/dist;|' /etc/nginx/sites-available/dbis-frontend && nginx -t && systemctl reload nginx"
```

### Issue: Dependencies missing
**Fix:** Install dependencies
```bash
pct exec 10130 -- bash -c "cd /opt/dbis-core/frontend && npm install"
```

## Next Steps After Verification

If verification passes:
1. ✅ Frontend is properly deployed
2. Clear browser cache
3. Access http://192.168.11.130
4. Should see the React app, not placeholder

If verification fails:
1. Run the fix script: `./scripts/fix-frontend-deployment.sh`
2. Check error messages
3. Review logs: `pct exec 10130 -- journalctl -u nginx -n 50`
