of the Mattermost trigger node for n8n, based on the [original work by Alexey Gusev](https://www.npmjs.com/package/n8n-nodes-mattermost-trigger), with added **reliable auto-reconnection** and **heartbeat monitoring**.\n\n## 🙏 Acknowledgments\n\nThis node is based on the original work by [Alexey Gusev](https://github.com/myluffe/n8n-nodes-mattermost-trigger). We've added auto-reconnection features and improved connection stability.\n\n## 🚀 Key Features\n\n- **Auto-reconnection** with exponential backoff (5s → 60s max)\n- **Heartbeat monitoring** with ping/pong (30s interval, 10s timeout)\n- **Connection resilience** - handles network drops, timeouts, and server restarts\n- **Production-ready logging** - minimal logs by default, debug mode available\n- **Infinite reconnection attempts** - never gives up until workflow deactivation\n- **Proper resource cleanup** - no memory leaks when stopping workflows\n\n## 🔧 Enhanced Connection Handling\n\n### Auto-reconnection Scenarios\n- ✅ **Network interruptions** - automatic reconnection with backoff\n- ✅ **Mattermost server restarts** - detects and reconnects seamlessly\n- ✅ **Connection timeouts** - handles slow/failed connections\n- ✅ **WebSocket errors** - graceful error handling and recovery\n- ✅ **Heartbeat failures** - detects silent connection drops\n\n### Connection Monitoring\n- **Ping/Pong heartbeat** every 30 seconds\n- **Connection timeout** detection (30s for initial connection)\n- **Pong timeout** handling (10s to receive pong response)\n- **Exponential backoff** with jitter (5s, 10s, 20s, 40s, 60s max)\n\n## 📦 Installation\n\n### Via n8n Community Nodes (Recommended)\n1. Open your n8n instance\n2. Go to **Settings** → **Community Nodes**\n3. Click **Install a community node**\n4. Enter: `@artymaximus/n8n-nodes-mattermost-trigger-enhanced`\n5.
