36-39: Excellent global error handler implementation.The middleware follows Express.js best practices with proper error logging and secure generic responses. Consider enhancing the logging for production environments.
For production environments, consider adding more structured logging:
app.use((err, req, res, next) => { - console.error(err.stack); + console.error('Error:', { + message: err.message, + stack: err.stack, + url: req.url, + method: req.method, + timestamp: new Date().toISOString() + }); res.status(500).json({ message: 'Internal Server Error' }); });

32-34: LGTM! Well-implemented 404 handler.The middleware correctly catches unmatched routes and provides a consistent JSON response format. The placement after route definitions ensures it only triggers for genuinely unmatched requests.
31-40: Perfect middleware placement and integration.The error handling middleware is strategically positioned after route definitions and before server startup, ensuring comprehensive error coverage. The implementation centralizes error handling as intended in the PR objectives and improves application robustness.

Implements robust error handling in an Express.js application using two middleware functions:
A 404 handler to catch undefined routes and respond with a Not Found message.
A global error handler to catch unexpected server errors, log the error stack, and respond with a standardized Internal Server Error message. This setup ensures consistent and secure error responses across the app.
