/pm2 Command

Auto-analyze project and generate PM2 service commands

/pm2 Command

Auto-analyze project and generate PM2 service commands for managing development services.

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
4. Update project CLAUDE.md with PM2 info
5. Display completion summary

Service Detection

Type	Detection	Default Port
Vite	vite.config.*	5173
Next.js	next.config.*	3000
Nuxt	nuxt.config.*	3000
CRA	react-scripts in package.json	3000
Express/Node	server/backend/api directory	3000
FastAPI/Flask	requirements.txt / pyproject.toml	8000
Go	go.mod / main.go	8080

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

Command Syntax

/pm2

No arguments required - auto-detects services.

Windows Configuration

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' }
    }
  ]
}

Terminal Commands

After init:

## First time (with config file)
pm2 start ecosystem.config.cjs && pm2 save

## After first time (simplified)
pm2 start all          # Start all
pm2 stop all           # Stop all
pm2 restart all        # Restart all
pm2 start {name}       # Start single
pm2 stop {name}        # Stop single
pm2 logs               # View logs
pm2 monit              # Monitor panel
pm2 resurrect          # Restore saved processes

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
