Inbox and Real-Time Notifications

In-app messaging service based on long-lived connections, supporting push notifications and unread message counts.

Project Background

Real-time messaging requires low latency while minimizing long-connection overhead. Node.js handles connections and message routing, while the frontend manages conversation lists and unread status.

Ideal for apps that need to reach users instantly.

Implementation Details

  • Automatically reconnect after disconnection and retrieve messages sent while offline.
  • Unread counts are managed centrally on the server to ensure consistency across all devices.
  • Enforce length and frequency limits on messages to reduce abuse risk.
