memorystream is a simple Node.js stream implementation that operates entirely in memory. It's perfect for testing stream-based APIs without having to rely on file system interactions or network connections. You can easily write data to the stream, read from it, and pipe data in and out. Its lightweight design makes it ideal for situations where you need a readily available, in-memory stream for development or debugging purposes, avoiding external dependencies or resource constraints.
The memorystream npm package has infrequent releases. There were releases in 2011 and 2012, with a period of inactivity until December 2014 and March 2015. Since then, there have been no new versions published up to August 2025. The package appears to be mostly unmaintained for the last decade.
Memorystream's npm package downloads show a general upward trend from March 2024 to June 2025, peaking at over 27 million. After June 2025, downloads decreased in July and August. September 2025 downloads are significantly lower, likely reflecting incomplete data for the current month.
