Releasing apps faster with feature flags
summary
A simple React app gets an emoji feature merged to main behind Split feature flags, deployed to prod same day instead of sitting on a long-lived branch. Internal users toggle access for testing in prod, the org runs four to five deploys a day, and a 50% rollout demonstrates gradual exposure. When errors appear the flag is flipped with a kill switch and the feature is turned off in seconds, avoiding urgent redeploys and letting engineers fix issues calmly.
