Scaling A/B Testing on with Node.js

By Chris Saint-Amant

Last Wednesday night we held our third JavaScript Talks event at our Netflix headquarters in Los Gatos, Calif. Alex Liu and Micah Ransdell discussed some of the unique UI engineering challenges that go along with running hundreds of A/B tests each year

We are currently migrating our website UI layer to Node.js, and have taken the opportunity to step back and evaluate the most effective way to build A/B tests. The talk explored some of the patterns we’ve built in Node.js to to handle the complexity of running so many multivariate UI tests at scale. These solutions ultimately enable quick feature development and rapid test iteration.

Slides from the talk are now online. No video this time around, but you can come see us talk about UI approaches to A/B testing and our adoption of Node.js at several upcoming events. We hope to see you there!
Lastly, don’t forget to check out our Netflix UI Engineering channel on YouTube to watch videos from past JavaScript Talks.
