description: Analyze a project and generate PM2 service commands for detected frontend, backend, or database services.

PM2 Init

Auto-analyze project and generate PM2 service commands.

Command: $ARGUMENTS

Workflow

1. Check PM2 (install via npm install -g pm2 if missing)
2. Scan project to identify services (frontend/backend/database)
3. Generate config files and individual command files

Service Detection

Port Detection Priority: User specified > .env > config file > scripts args > default port

Windows Configuration (IMPORTANT)

ecosystem.config.cjs

**Must use .cjs extension**

module.exports = {
  apps: [
    // Node.js (Vite/Next/Nuxt)
    {
      name: 'project-3000',
      cwd: './packages/web',
      script: 'node_modules/vite/bin/vite.js',
      args: '--port 3000',
      interpreter: 'C:/Program Files/nodejs/node.exe',
      env: { NODE_ENV: 'development' }
    },
    // Python
    {
      name: 'project-8000',
      cwd: './backend',
      script: 'start.cjs',
      interpreter: 'C:/Program Files/nodejs/node.exe',
      env: { PYTHONUNBUFFERED: '1' }
    }
  ]
}

Framework script paths:

Python Wrapper Script (start.cjs)

const { spawn } = require('child_process');
const proc = spawn('python', ['-m', 'uvicorn', 'app.main:app', '--host', '0.0.0.0', '--port', '8000', '--reload'], {
  cwd: __dirname, stdio: 'inherit', windowsHide: true
});
proc.on('close', (code) => process.exit(code));

Command File Templates (Minimal Content)

pm2-all.md (Start all + monit)

Start all services and open PM2 monitor.

cd "{PROJECTROOT}" && pm2 start ecosystem.config.cjs && start wt.exe -d "{PROJECTROOT}" pwsh -NoExit -c "pm2 monit"

pm2-all-stop.md

Stop all services.

cd "{PROJECT_ROOT}" && pm2 stop all

pm2-all-restart.md

Restart all services.

cd "{PROJECT_ROOT}" && pm2 restart all

pm2-{port}.md (Start single + logs)

Start {name} ({port}) and open logs.

cd "{PROJECTROOT}" && pm2 start ecosystem.config.cjs --only {name} && start wt.exe -d "{PROJECTROOT}" pwsh -NoExit -c "pm2 logs {name}"

pm2-{port}-stop.md

Stop {name} ({port}).

cd "{PROJECT_ROOT}" && pm2 stop {name}

pm2-{port}-restart.md

Restart {name} ({port}).

cd "{PROJECT_ROOT}" && pm2 restart {name}

pm2-logs.md

View all PM2 logs.

cd "{PROJECT_ROOT}" && pm2 logs

pm2-status.md

View PM2 status.

cd "{PROJECT_ROOT}" && pm2 status

PowerShell Scripts (pm2-logs-{port}.ps1)

Set-Location "{PROJECT_ROOT}"
pm2 logs {name}

PowerShell Scripts (pm2-monit.ps1)

Set-Location "{PROJECT_ROOT}"
pm2 monit

Key Rules

1. Config file: ecosystem.config.cjs (not .js)
2. Node.js: Specify bin path directly + interpreter
3. Python: Node.js wrapper script + windowsHide: true
4. Open new window: start wt.exe -d "{path}" pwsh -NoExit -c "command"
5. Minimal content: Each command file has only 1-2 lines description + bash block
6. Direct execution: No AI parsing needed, just run the bash command

Execute

Based on $ARGUMENTS, execute init:

1. Scan project for services
2. Generate ecosystem.config.cjs
3. Generate {backend}/start.cjs for Python services (if applicable)
4. Generate command files in `.claude/
