The rx-flux project provides two interesting examples, but no guidance as to how these are to be executed.
git clone https://github.com/fdecampredon/rx-flux.git
cd rx-flux/examples/flux-chat
npm install ../../
npm install
browserify js/app.js -o js/bundle.js
Open index.html in a browser.
Change directory to rx-flux/examples/flux-todomvc
and follow the same process.
