Just a step-by-step source reference for the official Facebook React Tutorial written in ES6 using gulp, browserify and Babel.
Official Tutorial: https://facebook.github.io/react/docs/tutorial.html
React ES6 reference: https://babeljs.io/blog/2015/06/07/react-on-es6-plus
Just git clone git@github.com:hadrons/react-tutorial-es6.git, npm install, gulp and point your browser to http://localhost:8080
Oh, you'll need the global gulp too, just npm install -g gulp
If you like oneliners:
git clone git@github.com:hadrons/react-tutorial-es6.git && cd react-tutorial-es6 && npm i -g gulp && npm i && gulp
Have fun :)
