Preventing WebSocket connection leaks requires explicitly closing sockets on success, timeout, or error, and clearing all associated timers and listeners. This ensures idempotent termination and avoids leaving connections open after they are no longer needed.

Cancel a real-time WebSocket subscription on React component unmount by integrating an AbortSignal. The socket listener responds to the external cancellation signal, triggering unified cleanup to close the connection safely and prevent resource leaks.

Handle WebSocket timeouts and errors without hanging promises by implementing explicit lifecycle rules. Applying unified cleanup to close sockets and clear timers on timeout or error prevents double resolve or reject and eliminates race conditions.

Your WebSocket listener duplicates events after a connection error because previous sockets were not closed properly. Implementing idempotent cleanup to remove listeners and close sockets on errors prevents duplicated listeners and lingering connections.

Yes, this WebSocket lifecycle management approach is specifically designed for long-lived subscriptions and real-time listeners. It supports external cancellation via AbortSignal and enforces explicit closure on success, timeout, error, or caller abort to ensure reliable termination.
