How do you handle reconnection logic in WebSockets?
Updated May 6, 2026
Short answer
Reconnection logic involves detecting disconnection events and retrying connection with backoff strategy.
Deep explanation
WebSockets do not automatically reconnect. Developers implement reconnection using exponential backoff to avoid overwhelming the server. The client listens to onclose and attempts reconnect after delays.
Real-world example
Chat applications automatically reconnect when internet drops.
Common mistakes
- Reconnecting too aggressively without delay causing server overload.
Follow-up questions
- What is exponential backoff?
- Should you store unsent messages?
