Overview

CrimsonWatch is a lightweight, background logging and security watcher written in TypeScript. It monitors targeted system/app log files in real-time, matching patterns using regular expressions (such as authentication failures, database timeouts, or critical error logs), and dispatches structured event notifications to external webhook endpoints.

Key Features

  • ⏱️ Live Stream Monitoring: Hooks into file system change events to tail files asynchronously with minimal resource footprints.
  • 🔍 Regex Matching Engine: Supports user-defined regex filters to capture specific alert signatures in log text.
  • webhook Notifications: Dispatches alerts containing context snippets to Slack, Discord, or generic webhook integrations.
  • 📦 Low Footprint: Optimized Node.js daemon running cleanly inside minimal Docker environments.
