lznext is a lightweight JavaScript library that implements an LZ‑based compression algorithm (compatible with Pieroxy’s original lz‑string). It provides UMD‑style modules for Node, ES6, and plain browser use, offering methods to compress/decompress strings and UTF‑16‑safe variants, and includes bug‑fixes beyond the upstream version. It’s aimed at web developers who need simple client‑side string compression, including those using CommonJS, ES modules, or Angular 1.
