Build a minimal feature flags manager in under an hour - Remi Mercier

When you deploy your code continuously, feature flags are a neat way to hide in-progress features from your users. In the past, I’ve written about my process for releasing large features. But after using feature flags in the last six months, I’ve come to like them better than my former process.Still, hiding behavior behind if ENV['MY-FEATURE'].present?-type conditionals bothers me.
