Node.js enables scalable backend APIs through event-driven architecture and non-blocking I/O. Use asynchronous patterns, HTTP servers, and streams to handle concurrent requests efficiently while maintaining performance at scale.

Asynchronous programming in Node.js relies on the event loop, callbacks, promises, and async/await to handle non-blocking I/O. These patterns prevent threads from blocking, allowing a single process to manage thousands of concurrent operations.

Yes, Node.js streams process large files and data without loading everything into memory. Streams support reading, writing, and transforming data in chunks, making them ideal for file systems, HTTP responses, and real-time data pipelines.

Production Node.js deployment requires security best practices, error handling, testing, and performance optimization. The Skill covers CommonJS and ES Modules, environment configuration, logging, and deployment patterns for cloud-native workloads.

Node.js is well-suited for microservices and real-time applications due to its event-driven model and lightweight footprint. Its non-blocking architecture handles concurrent connections efficiently for APIs, CLI tools, and real-time systems.

Robust error handling in Node.js backends involves structured logging, graceful degradation, and testing strategies. The Skill provides guidance on managing exceptions, timeouts, and recovery patterns to maintain reliability under load.
