grunt-react-boilerplate 
My boilerplate for starting React.js ES2015 based applications.
It uses Babel & Browserify to handle modules and compile them into plain clean Javascript, LESS for CSS.

Put your JS code into src/js directory. It will be automatically picked by Grunt Watch and bundeled into dist directory as app.js. Put all you LESS files into src/less and it will be compiled to dist/styles.less.
In order to create production ready build just run grunt build and change js src in index.html to point to dist/app.min.js.
