Best Practices

✅ DO

• Use middleware for cross-cutting concerns
• Implement proper error handling
• Validate input data before processing
• Use async/await for async operations
• Implement authentication on protected routes
• Use environment variables for configuration
• Add logging and monitoring
• Use HTTPS in production
• Implement rate limiting
• Keep route handlers focused and small

❌ DON'T

• Handle errors silently
• Store sensitive data in code
• Use synchronous operations in routes
• Forget to validate user input
• Implement authentication in route handlers
• Use callback hell (use promises/async-await)
• Expose stack traces in production
• Trust client-side validation only
