# Session End Event - Quick Start Guide

## 🚀 Quick Start

### Listen for Session End Events

```javascript
const WebSocket = require('ws');

const ws = new WebSocket('ws://localhost:5000/api/sessions/live');

ws.on('open', () => {
  // 1. Authenticate
  ws.send(JSON.stringify({
    type: 'auth',
    token: 'YOUR_JWT_TOKEN'
  }));
});

ws.on('message', (data) => {
  const msg = JSON.parse(data.toString());
  
  if (msg.type === 'auth_success') {
    // 2. Subscribe to session
    ws.send(JSON.stringify({
      type: 'subscribe',
      sessionId: 17
    }));
  }
  
  if (msg.type === 'session.ended') {
    // 3. Handle session end
    console.log('Session ended!');
    console.log(`Games played: ${msg.data.session.games_played}`);
    // Announce to your users here
  }
});
```

## 📦 Event Format

```json
{
  "type": "session.ended",
  "timestamp": "2025-11-01T02:30:45.123Z",
  "data": {
    "session": {
      "id": 17,
      "is_active": 0,
      "games_played": 5
    }
  }
}
```

## 🧪 Test It

```bash
# Get your JWT token first
curl -X POST http://localhost:5000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"key":"YOUR_ADMIN_KEY"}'

# Run the test script
node ../tests/test-session-end-websocket.js 17 YOUR_JWT_TOKEN

# In another terminal, close the session
curl -X POST http://localhost:5000/api/sessions/17/close \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"
```

## 🤖 Bot Integration

When your bot receives `session.ended`:

```javascript
if (msg.type === 'session.ended') {
  const { id, games_played } = msg.data.session;
  
  // Announce to IRC/Discord/etc
  bot.announce(`🌙 Game Night has ended! We played ${games_played} games.`);
  bot.announce('Thanks for playing!');
}
```
