Handling Disconnections and Reconnects
Implement client-side and server-side logic for detecting disconnections and automatically attempting reconnection.
Why Connections Drop
In the real world, network connections aren't always perfect. WebSockets, despite being persistent, can break due to many reasons.
Ignoring these disconnections can lead to unresponsive applications and a poor user experience. This lesson explores how to gracefully handle these interruptions.
Causes of Connection Loss
What makes a WebSocket connection drop?
- Network Issues: Wi-Fi drops, internet outages, proxy problems.
- Server Restarts: The server application might restart for updates or maintenance.
- Client Offline: The user closes their browser, loses power, or puts their device to sleep.
- Idle Timeouts: Some proxies or firewalls might close idle connections.
