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

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 + package.json	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

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:

Framework	script	args
Vite	node_modules/vite/bin/vite.js	--port {port}
Next.js	node_modules/next/dist/bin/next	dev -p {port}
Nuxt	node_modules/nuxt/bin/nuxt.mjs	dev --port {port}
Express	src/index.js or server.js	-

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

pm2-all-stop.md

Stop all services.
```bash
cd "{PROJECT_ROOT}" && pm2 stop all
```

pm2-all-restart.md

Restart all services.
```bash
cd "{PROJECT_ROOT}" && pm2 restart all
```

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

Start {name} ({port}) and open logs.
```bash
cd "{PROJECT_ROOT}" && pm2 start ecosystem.config.cjs --only {name} && start wt.exe -d "{PROJECT_ROOT}" pwsh -NoExit -c "pm2 logs {name}"
```

pm2-{port}-stop.md

Stop {name} ({port}).
```bash
cd "{PROJECT_ROOT}" && pm2 stop {name}
```

pm2-{port}-restart.md

Restart {name} ({port}).
```bash
cd "{PROJECT_ROOT}" && pm2 restart {name}
```

pm2-logs.md

View all PM2 logs.
```bash
cd "{PROJECT_ROOT}" && pm2 logs
```

pm2-status.md

View PM2 status.
```bash
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/commands/
5. Generate script files in .claude/scripts/
6. Update project CLAUDE.md with PM2 info (see below)
7. Display completion summary with terminal commands

---

Post-Init: Update CLAUDE.md

After generating files, append PM2 section to project's CLAUDE.md (create if not exists):

## PM2 Services

| Port | Name | Type |
|------|------|------|
| {port} | {name} | {type} |

**Terminal Commands:**
```bash
pm2 start ecosystem.config.cjs   # First time
pm2 start all                    # After first time
pm2 stop all / pm2 restart all
pm2 start {name} / pm2 stop {name}
pm2 logs / pm2 status / pm2 monit
pm2 save                         # Save process list
pm2 resurrect                    # Restore saved list
```

Rules for CLAUDE.md update:

• If PM2 section exists, replace it
• If not exists, append to end
• Keep content minimal and essential

---

Post-Init: Display Summary

After all files generated, output:

## PM2 Init Complete

**Services:**

| Port | Name | Type |
|------|------|------|
| {port} | {name} | {type} |

**Claude Commands:** /pm2-all, /pm2-all-stop, /pm2-{port}, /pm2-{port}-stop, /pm2-logs, /pm2-status

**Terminal Commands:**
## 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

**Tip:** Run `pm2 save` after first start to enable simplified commands.
