    PM2 Service Daemonizer — Node.js & Python Persistent Service Patterns

    Example session with this skill installed

    Deploy my Node.js api-server with 2 instances and my Python slack-bot using its venv. Ensure they both auto-start on server reboot.

    • Read your context and instructions
    • Compiled the pm2 service daemonizer

    [PM2] Spawning PM2 daemon with user [deploy]
    [PM2] App [api-server] launched (2 instances)
    [PM2] App [slack-bot] launched (python venv)
    [PM2] Script registered for startup at /etc/init.d/pm2-root
    [PM2] Actions: pm2 save | pm2 monit | pm2 logs
    Status: All 3 processes ONLINE. OS Auto-start ENABLED.

    About this skill

    Turn Scripts into Reliable Background Services

    Deploying an application is only the first step; keeping it running 24/7 is the real challenge. pm2-service-daemonizer provides a standardized workflow for transforming Node.js, Python, and binary applications into resilient background daemons. It solves the critical problem of "silent failures" where a script crashes or a server reboots, leaving your service offline.

    What it does

    This skill automates the end-to-end process of service lifecycle management. It encapsulates complex configurations for process persistence, including:

    • Daemonization: Running applications in the background with zero-downtime reloads.
    • Auto-Recovery: Instant restarts if an app crashes due to memory leaks or unhandled exceptions.
    • Boot Persistence: Configuring system-level startup scripts (Mac/Linux) to ensure services come back online after a power cycle.
    • Runtime Management: Unified logging, health checks, and resource monitoring for multiple processes.

    Why use this skill

    Manually running commands like pm2 start is easy, but configuring pm2 startup correctly, managing Python virtual environments, or handling cross-platform daemon persistence is error-prone. This skill acts as a DevOps expert, ensuring your environment variables, work directories, and startup hooks are configured according to production-grade best practices.

    Supported Technologies

    • Frameworks: Node.js (Express, NestJS), Python (Flask, FastAPI, Slack-Bolt).
    • Environments: Virtualenv, Conda, npm/yarn.
    • Platforms: Linux (Ubuntu, CentOS, Debian), macOS.
