Running a seasonally themed signup experiment with LaunchDarkly and ExpressJS

This tutorial demonstrates how to run an A/B experiment using LaunchDarkly and ExpressJS to test the impact of seasonal CSS on signup conversions for a costume shop website. The process involves creating a metric, setting up an experiment with flags, adding event tracking and flag evaluation to the ExpressJS routing layer, and observing the results in the LaunchDarkly app. This method allows developers to gather data about the impact of changes to their product and make informed decisions based on that data.
