Version 2.0.8 is current stable; released via npm, maintained by Gajus Kuizinas. Requires Perl on the host system. Ships TypeScript type definitions. Supports customizable formatting options like keyword/function case, indentation spaces/tabs, comma breaking, anonymization, placeholder regex, and comment stripping.
