Feature toggles: shipping fast without breaking things

Whenever I ship a change, I deploy a toggle alongside it. A boolean flag keeps the experience guarded, so we can flip it without redeploying.

Best practices

  • Attach each toggle to a measurable metric or automated test.
  • Make toggles configurable via a dashboard—LaunchDarkly, ConfigCat, or a JSON file.
  • Clean up stale toggles: create a cleanup ticket as soon as a feature stabilizes.

With this approach, we deploy major changes with confidence. Flip the feature server-side, observe behavior, and roll out incrementally.
