6 resilience patterns for WebSocket clients, extracted from real-world mobile network conditions.

Mobile WebSocket connections fail in ways that local development environments don't surface. P99 latency on 4G networks is 5-8 seconds. A 5-second health check timeout causes false positives on every slow network.

When to use: Implementing WebSocket client reconnection logic, building real-time features with persistent connections, mobile app WebSocket handling, any client that maintains long-lived server connections.

クライアント側の WebSocket 復元パターン: ジッターを伴うバックオフ、サーキット ブレーカー、ハートビート ヒステリシス、コマンド確認応答、シーケンス ギャップ検出、およびモバイル対応タイムアウト。 ソース: apankov1/quality-engineering。
