Add error codes in addition to messages +5. Add retry logic for transient failures +6. Add metrics/analytics for error rates + +## Migration Guide + +For adding ACKs to new events: + +### Server-side: +```javascript +socket.on('your-event', (data, callback) => { + try { + // ... your logic + + if (callback) { + callback({ + ok: true, + // ... your success data + }); + } + } catch (error) { + console.error('Error in your-event:', error); + if (callback) { + callback({ + ok: false, + error: 'Error message: ' + error.message + }); + } + } +}); +``` + +### Client-side: +```javascript +socket.emit('your-event', { data }, (response) => { + console.log('[your-event ACK]', response); + + if (!response?.ok) { + const errorMsg = response?.error || 'Erreur inconnue'; + console.error('Your event failed:', errorMsg); + alert('Operation failed: ' + errorMsg); + return; + } + + // Success handling + console.log('Operation successful'); +}); +``` + +## Conclusion + +This implementation significantly improves the user experience by providing clear feedback when operations fail. The consistent ACK pattern makes the codebase more maintainable and follows Socket.IO best practices. Error messages are now displayed to users, eliminating the frustrating "ça ne fait rien" experience.

Verify health endpoint works: `curl http://localhost:7779/health` +2. Check AMP health check configuration +3. Ensure AMP is pointing to correct URL and port +4. Check AMP logs for health check errors +5. Increase health check timeout in AMP settings + +## Security Considerations + +### Public Exposure + +Health check endpoints are safe to expose publicly because they: +- Don't reveal sensitive information +- Don't perform authentication (by design) +- Don't modify server state +- Provide minimal server details + +### Rate Limiting + +For production deployments, consider adding rate limiting: + +```javascript +const rateLimit = require('express-rate-limit'); + +const healthCheckLimiter = rateLimit({ + windowMs: 1 * 60 * 1000, // 1 minute + max: 100 // limit each IP to 100 requests per minute +}); + +app.get('/health', healthCheckLimiter, (req, res) => { + res.status(200).json({ + status: 'ok', + timestamp: Date.now() + }); +}); +``` + +### Firewall Rules + +Recommended firewall configuration: +- Allow `/health`, `/status`, `/ping` from monitoring IPs +- Allow all endpoints from localhost (127.0.0.1) +- Rate limit public access + +## Implementation Details + +### Code Location + +Health check endpoints are defined in `server.js` after port configuration and before static file serving: + +```javascript +const PORT = process.env.PORT || 7779; + +// Health check endpoints for deployment systems +app.get('/health', (req, res) => { + res.status(200).json({ + status: 'ok', + timestamp: Date.now() + }); +}); + +app.get('/status', (req, res) => { + res.status(200).json({ + status: 'running', + port: PORT, + rooms: rooms.size, + uptime: process.uptime() + }); +}); + +app.get('/ping', (req, res) => { + res.status(200).send('pong'); +}); + +// Serve static files +app.use(express.static(__dirname)); +``` + +### Why Before Static Files? + +Health check endpoints are defined before `express.static()` middleware to ensure: +1. They take precedence over static file serving +2. Faster response (no file system checks) +3. Clear separation of concerns + +### Response Format + +All endpoints follow standard conventions: +- `/health`: JSON with status and timestamp (industry standard) +- `/status`: JSON with detailed metrics (monitoring standard) +- `/ping`: Plain text (minimal overhead) + +## Testing + +### Manual Testing + +```bash +# Start server +npm start + +# In another terminal: +curl http://localhost:7779/health +curl http://localhost:7779/status +curl http://localhost:7779/ping + +# Check HTTP status codes +curl -I http://localhost:7779/health +``` + +### Automated Testing + +```javascript +// test-health.js +const http = require('http'); + +function testHealthEndpoint() { + return new Promise((resolve, reject) => { + http.get('http://localhost:7779/health', (res) => { + let data = ''; + res.on('data', chunk => data += chunk); + res.on('end', () => { + const json = JSON.parse(data); + if (res.statusCode === 200 && json.status === 'ok') { + console.log('✅ Health check passed'); + resolve(true); + } else { + console.log('❌ Health check failed'); + reject(false); + } + }); + }).on('error', reject); + }); +} + +testHealthEndpoint(); +``` + +## Conclusion + +The addition of health check endpoints resolves the AMP deployment system issue by providing a standard way to verify the server is healthy and ready. These endpoints: + +✅ Allow deployment systems to exit "update" mode +✅ Enable monitoring and alerting +✅ Provide debugging information +✅ Follow industry best practices +✅ Have minimal performance impact +✅ Don't change existing functionality + +The server now properly signals readiness to AMP Cubecoder and other deployment systems, eliminating the perpetual "update" state issue.

State-Aware Input Handling + +**Core Function** (`js/Game.js`): +```javascript +isGameplayActive() { + return this.gameState && this.gameState.isState(GameStates.RUNNING); +} +``` + +This function is the **single source of truth** for whether input should be processed for gameplay or ignored for menus. + +### 2. Canvas Touch Event Guards + +**Implementation** (`js/Game.js` - `setupCanvasTouchHandlers()`): + +```javascript +this.canvas.addEventListener('touchstart', (e) => { + if (!this.isGameplayActive()) { + // In menus: allow normal touch behavior (enables clicks) + return; + } + // In gameplay: prevent scroll/zoom + e.preventDefault(); +}, { passive: false }); +``` + +**Key Points**: +- ✅ Only listens on `canvas` element, not `document` or `window` +- ✅ Checks state before calling `preventDefault()` +- ✅ Uses `{ passive: false }` to allow preventDefault when needed +- ✅ Returns early in menus, allowing normal click generation + +### 3.
