Real-Time Updates

​

Overview

The Syngenta Warehouse Management System will use real-time data synchronization to ensure all users see the most current information instantly. Whether tracking inventory movements, monitoring order status, or collaborating with team members, real-time updates will keep everyone on the same page.

​

How Real-Time Updates Work

The system uses a multi-layered approach to deliver real-time data:

​

Technology Stack

Next.js 15+ with React Server Components

• Server-side rendering for fast initial page loads
• Client-side hydration for interactive features
• Optimistic updates for instant user feedback

next-themes Integration

• Seamless theme switching (light/dark modes)
• No flash of unstyled content
• Preference persistence across sessions

WebSocket Connections

• Persistent bidirectional communication
• Sub-second latency for data updates
• Automatic reconnection on network issues

Server-Sent Events (SSE)

• One-way server-to-client updates
• Fallback for environments blocking WebSockets
• Lower resource usage for read-only data

​

​

Real-Time Collaboration Scenarios

​

Scenario 1: Concurrent Inventory Count

Two users counting inventory simultaneously:

​

Scenario 2: Order Rush Hour

Multiple orders arriving simultaneously:

• Orders appear on all dashboards in real-time as they’re created
• Team lead assigns orders to pickers
• Pickers receive instant notifications on mobile devices
• As items are picked, inventory depletes in real-time
• Managers see live fulfillment progress
• Shipping team notified immediately when orders are ready to pack

​

Scenario 3: Low Stock Alert

Automated real-time threshold monitoring:

1. Stock level drops below reorder point
2. Alert instantly appears on:
   • Manager dashboards
   • Inventory supervisor screens
   • Purchasing system (via integration)
3. Purchase order created automatically
4. All stakeholders notified of reorder action
5. Stock replenishment tracked in real-time

​

Performance Optimization

Real-time updates are optimized to avoid overwhelming users:

​

Smart Batching

• Multiple rapid changes batched into single updates
• Prevents UI flickering from constant updates
• Reduces network traffic and CPU usage

​

Selective Subscriptions

• Only subscribe to data relevant to current view
• Automatic unsubscribe when navigating away
• Reduces bandwidth and processing overhead

​

Update Throttling

• High-frequency updates throttled to human-perceivable rates
• Charts update max once per second (even if data changes more often)
• Metric cards refresh at 30-second intervals

​

Theme Switching with Real-Time Sync

The system uses next-themes for seamless theme management:

​

​

Troubleshooting Real-Time Updates

Updates not appearing in real-time

Diagnostic Steps:

1. Check connection indicator in header (should be green)
2. Verify internet connection is stable
3. Disable browser extensions that may block WebSockets
4. Check if firewall/proxy is blocking real-time protocols
5. Try refreshing the page (Cmd/Ctrl + R)
6. Clear browser cache and cookies

Common Causes:

• Corporate firewall blocking WebSocket connections
• VPN interference with real-time protocols
• Browser extensions (ad blockers, privacy tools)
• Outdated browser version

Solution: Contact IT to whitelist WebSocket connections for the warehouse system domain.

Connection keeps dropping

Possible Solutions:

• Check Wi-Fi signal strength (move closer to access point)
• Test network stability (run speed test)
• Switch to wired connection if available
• Reduce network congestion (close unnecessary apps/tabs)
• Contact IT if problem is widespread

Temporary Workaround: Enable “Low Bandwidth Mode” in Settings > Performance to reduce connection requirements.

Conflicting changes error

What it means:Another user modified the same data while you were editing it.Resolution Steps:

1. System displays both versions (yours and theirs)
2. Review the differences highlighted in the comparison view
3. Choose to:
   • Keep your changes (overwrites their version)
   • Accept their changes (discards your edits)
   • Merge both (manually combine changes)
4. Confirm your choice to resolve the conflict

Be cautious when overwriting others’ changes. Communicate with your team to prevent data loss.

Notifications not appearing

Check these settings:

1. Browser notification permissions granted
2. System notifications enabled in Settings
3. Specific notification types not disabled
4. Not in “Do Not Disturb” mode
5. Browser is in foreground (background tabs may suppress notifications)

Enable browser notifications:

• Chrome/Edge: Settings > Privacy > Site Settings > Notifications
• Firefox: Preferences > Privacy & Security > Permissions
• Safari: Preferences > Websites > Notifications

Data seems outdated

Quick Fixes:

1. Force refresh: Cmd/Ctrl + Shift + R
2. Check last sync time in connection indicator
3. Verify you’re not in offline mode
4. Log out and log back in
5. Clear browser cache

If problem persists: There may be a server-side sync issue. Contact support with:

• Time you noticed the issue
• Specific data that appears outdated
• Screenshots if possible

Best Practices

​

For All Users

• Trust the system: No need to manually refresh; updates happen automatically
• Monitor connection: Glance at connection indicator periodically
• Sync before critical actions: Ensure green connection status before important operations
• Report sync issues: Help IT identify and fix problems early

​

For Mobile Users

• Maintain Wi-Fi connection: Use warehouse Wi-Fi rather than cellular when possible
• Keep app in foreground: Background apps may miss real-time updates
• Sync before going offline: Ensure latest data is cached before entering dead zones
• Enable notifications: Stay informed even when not actively using the app

​

For Managers

• Leverage real-time dashboards: Make decisions based on current data
• Set up critical alerts: Configure notifications for important thresholds
• Monitor team activity: Use real-time indicators to coordinate work
• Review sync logs: Check for patterns in connection issues

​

For Administrators

• Monitor server load: Track real-time connection counts and performance
• Optimize network: Ensure adequate bandwidth for WebSocket connections
• Configure firewalls: Whitelist real-time protocols
• Plan for scaling: Monitor connection growth and plan capacity

​
