A toggle is a switch that allows you to switch between two states or options. Toggles are commonly used in technology, computing, programming, and communications to provide users with a way to customize or personalize the experience.

Feature Toggles are powerful tools for any dev team to use as part of their continuous delivery practices. They can be used for experimentation, to act as circuit breakers in production, or even for validating features with a subset of users before rolling them out to all.

The best way to manage toggle configuration is through a dynamic approach. While it is possible to hardcode toggle configuration using comments or some other method, this quickly becomes cumbersome at scale and can create a lot of additional maintenance overhead.

Many teams choose to move their toggle configuration into some form of centralized store, often an existing application DB, and then build out a management UI for product teams and testers to view and modify feature flags and their configuration. This helps to reduce the maintenance overhead of managing the toggles and also ensures that the underlying code will always be up to date, even after a release has been rolled out.

Regardless of the method you choose to use for storing and managing your toggles, make sure that they are clearly labeled and are consistent with the rest of your interface design. It is also a good idea to use visual cues like movement or color changes to indicate the state of a toggle. This will help avoid cognitive issues that can arise when a toggle isn’t clearly differentiated from other controls in the system.
