ws-heartbeat

Lightweight heartbeat/ping-pong library for WebSocket connections, compatible with both server-side (ws library) and browser-side WebSocket. Version 1.3.0 provides a simple API to detect dead connections and maintain active WebSocket sessions. Differentiates from manual ping/pong implementations by handling intervals, timeouts, and automatic cleanup. No native WebSocket ping frames required, works with any message format. Low dependency footprint.
