PMDaemon v0.1.0 - Initial Release 🚀

We are excited to announce the first release of PMDaemon - a high-performance process manager built in Rust, inspired by PM2 with innovative features that exceed the original.

🎉 Highlights

PMDaemon brings modern process management to Rust with production-ready features and performance benefits. This initial release includes all core PM2 functionality plus several innovative features not found in the original PM2.

✨ Key Features

Core Process Management

  • Complete lifecycle management - Start, stop, restart, reload, and delete processes
  • Clustering support - Run multiple instances with automatic load balancing
  • Auto-restart on crash - Configurable restart limits and strategies
  • Graceful shutdown - Proper signal handling (SIGTERM/SIGINT)
  • Configuration persistence - Process configs saved/restored between sessions
  • Multi-session support - Processes persist across CLI sessions

🌟 Innovative Features (Beyond PM2)

  • Advanced Port Management
    • Port range distribution for clusters (--port 3000-3003)
    • Auto-assignment from ranges (--port auto:5000-5100)
    • Built-in conflict detection
    • Runtime port overrides without config changes
    • Port visibility in process listings
  • Memory Limit Enforcement - Automatic restart when exceeding limits (--max-memory 100M)
  • WebSocket Support - Real-time process updates and monitoring
  • Enhanced CLI Display - Color-coded statuses and formatted tables

Monitoring & Logging

  • Real-time monitoring - CPU, memory, uptime tracking
  • System metrics - Load average, total memory usage
  • Log management - Separate stdout/stderr files
  • PID file tracking - Reliable process discovery

Web API & Integration

  • REST API - Full process management via HTTP
  • PM2-compatible responses - Drop-in replacement potential
  • WebSocket endpoint - Live status updates
  • CORS support - Production-ready security headers

📊 Project Stats

  • 158 tests (120 unit + 11 integration + 8 e2e + 19 doc tests)
  • 7 completed development phases
  • 100% core feature coverage
  • Production-ready stability

🚀 Quick Start

# Install via Cargo
cargo install pmdaemon

# Start a process
pmdaemon start app.js --name myapp

# Start a cluster with port distribution
pmdaemon start server.js --instances 4 --port 3000-3003

# Monitor processes
pmdaemon monit

# Start web API
pmdaemon web --port 9615

📦 What's Included

  • ✅ All PM2 core commands (start, stop, restart, reload, delete, list, logs, monit)
  • ✅ Process clustering with load balancing
  • ✅ Environment variable management
  • ✅ Working directory configuration
  • ✅ Auto-restart with memory limits
  • ✅ Real-time monitoring with formatted output
  • ✅ Web API with WebSocket support
  • ✅ Comprehensive error handling
  • ✅ Cross-platform support (Linux, macOS, Windows)

🔧 Technical Details

  • Built with Rust for performance and memory safety
  • Async/await architecture using Tokio
  • Web server powered by Axum
  • System monitoring via sysinfo
  • Comprehensive test coverage

🙏 Acknowledgments

This project was inspired by the excellent PM2 process manager. While PMDaemon aims to provide similar functionality, it leverages Rust's performance and safety benefits while adding innovative features for modern deployment scenarios.

📝 Notes

This is our initial release. We've thoroughly tested all features, but if you encounter any issues, please report them on our GitHub repository.

🚀 Get Started

cargo install pmdaemon
