(yet) - BabelMinify can because it is just a set of Babel plugins, and Babel already understands new syntax with our parser [Babylon](https://github.com/babel/babylon). - When it's possible to only target browsers that support newer ES features, code sizes can be smaller because you don't have to transpile and then minify. Check out our [blog post](http://babeljs.io/blog/2016/08/26/babili) for more info! ```js // Example ES2015 Code class Mangler { constructor(program) { this.program = program; } } new Mangler(); // without this it would just output nothing since Mangler isn't used ``` Before ```js // ES2015+ code -> Babel -> BabelMinify/Uglify -> Minified ES5 Code var a=function a(b){_classCallCheck(this,a),this.program=b};new a; ``` After ```js // ES2015+ code -> BabelMinify -> Minified ES2015+ Code class a{constructor(b){this.program=b}}new a; ``` ## [CLI](http://babeljs.io/docs/usage/cli/) | Package | Version | Dependencies | |--------|-------|------------| | [`babel-minify`](/packages/babel-minify) | [](https://www.npmjs.com/package/babel-minify) | [](https://david-dm.org/babel/babel-minify?path=packages/babel-minify) | ### Install ```sh npm install babel-minify --save-dev ``` ### Usage ```sh minify src -d lib ``` ## [Babel preset](http://babeljs.io/docs/plugins/#presets) | Package | Version | Dependencies | |--------|-------|------------| | [`babel-preset-minify`](/packages/babel-preset-minify) | [](https://www.npmjs.com/package/babel-preset-minify) | [](https://david-dm.org/babel/minify?path=packages/babel-preset-minify) | ### Install ```sh npm install babel-preset-minify --save-dev ``` ### Usage You'll most likely want to use it only in the production environment. Check out the [env docs](http://babeljs.io/docs/usage/babelrc/#env-option) for more help. > Options specific to a certain environment are merged into and overwrite non-env specific options. `.babelrc`: ``` { "presets": ["es2015"], "env": { "production": { "presets": ["minify"] } } } ``` Then you'll need to set the env variable which could be something like `BABEL_ENV=production npm run build` ## Individual Plugins The `minify` repo is comprised of many npm packages. It is a [lerna](https://github.com/lerna/lerna) monorepo similar to [babel](https://github.com/babel/babel) itself.
