Node.js remains a popular choice for building high-concurrency services due to its non-blocking I/O model. This article explores key engineering patterns, including event loop optimization to avoid blocking and stream-based processing for efficient data handling. Developers can apply these patterns to improve throughput and reduce latency in production systems. While the concepts are well-established, the article provides a consolidated reference for teams scaling Node.js applications. The focus on practical implementation makes it useful for backend engineers and architects.
A practical guide to designing high-concurrency Node.js services with event loop optimization and streaming.
