Roll Your Own A/B Tests With Optimizely and React - Tilt Engineering Blog

At Tilt, our growth team uses Optimizely to do light-weight experiments like inject text into the navbar, change styles, or adjust static pages to test out different designs. Optimizely allows you to easily A/B test your website by injecting client-side JavaScript to do things like inject inline styles or change button text. However, our engineers also use Optimizely for richer experiments – showing completely different versions of the homepage, updating the behavior of a JavaScript widget, and rolling out new product features to employees first for testing. In this post I’ll walk through our experiment setup and show how we use React.js together with the Flux architecture to build an application whose behavior can be easily changed through Optimizely.
