babel-preset-es2015-minimal-rollup

2.1.1 verified Mon Apr 27 auth: no javascript deprecated

A lightweight Babel 6 preset for transpiling ES2015 (ES6) to ES5 in loose mode, specifically optimized for Rollup bundlers. Version 2.1.1 is the current stable release; the package is deprecated and no longer maintained. It reduces the overhead of the full babel-preset-es2015 by removing frills, making it ideal for tree-shaking with Rollup. Key differentiator: minimal configuration with loose mode transforms to produce smaller Rollup output, unlike the standard preset.
