Building Scalable APIs with Node.js

Building scalable APIs requires careful consideration of architecture, error handling, and performance optimization. ## API Design Principles Follow RESTful conventions and use appropriate HTTP status codes. Design your API to be intuitive and self-documenting. ## Error Handling Strategy Implement comprehensive error handling with proper logging and monitoring. Use middleware to handle errors consistently across your application. ## Database Optimization Optimize database queries and consider implementing caching strategies for frequently accessed data. Connection pooling is essential for production applications.
