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.
