  • Scaling A/B testing with Node.js
  • Time: TBD | Room: E-132
Netflix performs hundreds of UI A/B tests every year. In order to quickly iterate on tests and their results, we have developed several solutions for reducing complexity and streamlining development for UI engineers. Our Node.js stack is tuned for quick feature development and rapid test iteration and has lead to several interesting patterns around template loading and asset (css, js) and HTML (view) packaging.
