yauzl is a pure-Javascript streaming zip file reader/unzipper, offering asynchronous, non-blocking access to entries within zip archives. Designed for speed and efficiency, it avoids buffering entire files into memory, making it suitable for large archives and resource-constrained environments. yauzl empowers developers to programmatically extract or process individual files from zip archives, providing granular control over the unzipping process and minimizing memory overhead. Its streaming nature makes it ideal for server-side applications or environments where memory usage is a primary concern.
