Robust Error Propagation and Recovery

Building reliable realtime applications requires more than just handling disconnections. You need a solid strategy for dealing with errors that occur within your WebSocket communication.

Robust error handling ensures your application remains stable, provides a good user experience, and helps you diagnose issues quickly.

Errors in WebSocket applications can come from various sources:

• Protocol Errors: These are issues like malformed frames or invalid opcodes. Your WebSocket library usually handles these automatically.
• Application Logic Errors: Bugs in your server or client code that cause unexpected behavior or crashes during message processing.
• Network Errors: Problems like firewalls, proxy issues, or unstable internet connections, often leading to connection loss.

We'll focus on handling application and network-related errors effectively.
