Building Reliable WebSocket Connections for Real-Time Restaurant Operations

When you're building real-time systems for industries like food service, reliability isn't optional. A dropped WebSocket connection during a dinner rush means lost orders, confused staff, and unhappy customers. Here's what I've learned building WebSocket infrastructure for restaurant operations platforms. The Problem Space Restaurant operations generate a constant stream of events: new phone calls, reservation updates, order modifications, table status changes, and kitchen notifications. HTTP polling falls apart at this scale — you need persistent, bidirectional connections that can handle bursts of activity during peak hours. The challenge is that restaurants operate in environments hostile to stable connections. Staff move between WiFi dead zones, POS terminals run on aging hardware, and the kitchen's microwave occasionally knocks out the 2.4GHz band entirely. Connection Architecture The foundation is a reconnection strategy that handles the full spectrum of failure modes: class Reli
