A lightweight Babel preset that applies every ES2015 transformation **except** the CommonJS module conversion, allowing Webpack 2 to keep native `import`/`export` syntax for tree‑shaking. It’s intended for front‑end developers who want their ES6 code compiled to ES5 while preserving module syntax for optimal bundling with Webpack. (Now deprecated—use the built‑in `es2015` preset with `{ "modules": false }`.)
