Changelog

All notable changes to NodeDaemon will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[1.1.0] - 2025-07-23

Added

  • Web UI Dashboard - Real-time process monitoring and control interface
    • Live CPU, memory, and uptime metrics with WebSocket updates
    • Interactive process control (start, stop, restart, reload)
    • Beautiful dark theme responsive design
    • Zero external dependencies - built-in HTTP and WebSocket servers
    • Authentication support with username/password
    • Configurable port and host binding
  • New CLI commands for Web UI management:
    • nodedaemon webui start - Start the Web UI server
    • nodedaemon webui stop - Stop the Web UI server
    • nodedaemon webui status - Check Web UI status
  • WebSocket protocol implementation without external packages
  • RESTful API endpoints for process management
  • Real-time log streaming support (foundation laid)

Fixed

  • File watching now correctly detects changes and triggers restarts
    • Fixed path comparison issue (relative vs absolute paths)
    • Removed incorrect unwatch behavior in FileWatcher
  • Memory usage reporting on Windows systems
    • Fixed WMIC output parsing for accurate memory metrics
    • Corrected array indices for memory data extraction
  • Process metrics now properly aggregated at process level
    • CPU and memory data correctly summed across instances
    • Uptime calculated from instance start time

Changed

  • Enhanced API response format to include aggregated metrics
  • Improved health monitoring with proper metric updates
  • Better error handling in Web UI operations

[1.0.2] - 2025-07-22

Added

  • Enhanced process health monitoring with more detailed metrics
  • Improved daemon stability and performance
  • Better error handling for edge cases
  • Smart restart mechanism with exponential backoff
  • Restart counter reset after successful minimum uptime
  • Permanent stop after reaching max restart attempts
  • New --min-uptime option to configure restart counter reset threshold
  • Auto-restart on high memory/CPU usage with configurable thresholds
  • New options: --auto-restart-memory, --auto-restart-cpu, --memory-threshold, --cpu-threshold
  • Environment file support with --env-file option (supports .env, .env.local, etc.)
  • Graceful reload for zero-downtime restarts in cluster mode with --graceful flag

Fixed

  • Minor bug fixes and improvements
  • Memory usage optimization for long-running processes
  • Prevented restart loops for processes with port conflicts or critical errors

Changed

  • Updated internal dependencies for better compatibility
  • Improved logging for restart attempts with detailed backoff information
  • Default minimum uptime set to 10 seconds for restart counter reset

[1.0.1] - 2025-07-22

Fixed

  • Fixed daemon startup issue where wrong script file was being executed
  • Added daemon startup verification to ensure it's running before reporting success
  • Improved error messages when daemon fails to start

Changed

  • Daemon now properly starts from daemon/index.js instead of daemon/NodeDaemonCore.js

    • Cluster mode support with automatic load balancing
    • File watching with intelligent debouncing
    • Daemon mode for background operation
    • IPC communication via Unix sockets/Windows named pipes
    • State persistence across daemon restarts
    • Comprehensive logging with rotation and compression
    • Health monitoring with automatic restarts
    • Graceful shutdown handling

  • CLI Commands

    • daemon - Start the daemon process
    • start - Start a new process

    • No external npm packages required
    • Single-file executable distribution

  • Platform Support

    • Full Windows support with named pipes
