This is a simple as can be react project made as a setup exercise. It's written in glorious ES6 (without all those pesky semicolons), and the Flux architecture for react.js and alt.
Simply clone the repo, run 'npm install' to install all the requisite node modules, then run 'npm run-script build'
The built js file is build/react_test.js and you can see the app's main page in public/react_test.html
When running the app, you can install alt-devtool to see the current state of the TestStore store and all actions dispatched.
