Feature toggle is a mechanism that allows code to be turned “on” or “off” remotely without the need for a deploy. Feature toggles are commonly used in applications to gradually roll out new features, allowing teams to test changes on a small subset of users before releasing them to everyone.
Feature toggle is typically a logical check added to codebase to execute or ignore certain functionality in context based on evaluated status of the toggle at runitme.
In code, the functionality to be released is wrapped so that it can be controlled by the status of a feature toggle. If the status of the feature toggle is “on”, then the wrapped functionality is executed. If the status of the feature toggle is “off”, then the wrapped functionality is skipped. The statuses of each feature is provided by a store provider external to the application.
The primary benefit of feature flagging is that it mitigates the risks associated with releasing changes to an application. Whether it be a new feature release or a small refactor, there is always the inherent risk of releasing new regressions. To mitigate this, changes to an application can be placed behind feature toggles, allowing them to be turned “on” or “off” in the event of an emergency.
