Using streams in Node.js enables efficient processing of large amounts of data without loading everything into memory, making applications more performant and scalable. As the creator of CoreUI with over 25 years of software development experience, I’ve implemented streams extensively in data processing pipelines, file operations, and real-time applications. From my expertise, the most effective approach is understanding the four types of streams: readable, writable, duplex, and transform streams. This pattern enables memory-efficient data processing for applications handling large files, real-time data, or high-throughput operations.
