rollup-plugin-cleanup

Rollup plugin for removing JavaScript comments, compacting empty lines, trimming trailing spaces, and normalizing line endings. Current stable version 3.2.1 supports Rollup >=2.0 and Node.js >=10.14.2 or >=12.0.0. Unlike minifiers like Uglify, it preserves coding style and gives fine-grained control over comment removal via configurable filters. Since v3.1, it no longer depends on acorn, relying instead on js-cleanup. Offers TypeScript definitions, sourcemap support, and works with JS-like files (TS, Flow, React, ES9+).
