minizlib is a fast, lightweight zlib stream library built on minipass and Node.js's zlib binding, designed for high-performance compression and decompression without the overhead of Node's built-in zlib streams. It provides synchronous streams for formats like Deflate, Gzip, Brotli, and Zstd, making it ideal for use cases where speed and minimal memory usage are critical, such as in node-tar and minipass-fetch. This library is best suited for Node.js developers needing efficient streaming compression/decompression, especially when built-in zlib's async overhead is unnecessary.
