unzipit.js

unzipit.js is a JavaScript library providing efficient, random-access decompression of ZIP archives in both browser and Node.js environments. Currently stable at version 2.0.1, it offers significant performance advantages, claiming 6x to 25x faster extraction speeds than alternatives like JSZip, coupled with considerably lower memory consumption. A key differentiating feature is its ability to perform partial downloads of ZIP files by leveraging HTTP range requests, allowing selective extraction without fetching the entire archive. The library supports parallel processing through web workers, further enhancing speed. It accepts various input types, including URLs, Blobs, ArrayBuffers, and custom `Reader` implementations, making it versatile for diverse use cases. While designed for ESM, it also provides a CommonJS entry point for Node.js projects, with recent versions (Node >=18) primarily favoring ES Modules.
