jsmin

jsmin is a Python library and command-line tool for minifying JavaScript code, based on Douglas Crockford's original jsmin.c. It removes unnecessary whitespace and comments to reduce file size. The current version is 3.0.1. The project is actively maintained, though the maintainer has stated they do not intend to add ECMAScript 6 (ES6) compatibility, indicating a focused maintenance cadence for its existing feature set.
