What is a Toggle?

Toggle is a switch that allows you to turn on and off functionality in a piece of hardware or software. Toggles can be found in every day technology like the Caps Lock or Num Lock buttons on keyboards or the options menus in most applications. They work the same way by initially being off and when activated they turn on a specific function. Then when pressed again they will turn that function off.

For software applications, toggles are usually implemented as boolean variables, and are used to control a program. They are often set to a default value when the application is opened. This can be a bit confusing for users who are accustomed to other settings, and it is important to make clear how the toggle functions when it is first introduced.

In addition to providing the option to enable/disable features, toggles also provide an opportunity for developers to provide their users with personalized experiences by allowing them to customize colors or themes in applications. This is a great way to offer users a more customizable experience, and can help reduce cognitive load in cases where the options are many.

Another common use of toggles is in the design of UI elements. It is common for developers to implement toggles that allow the user to choose between light or dark versions of a given UI element, to suit their own visual preferences. While this may seem trivial, it can be very helpful to some users who have difficulty navigating a digital environment, and allowing them to toggle between different styles can make the difference in whether or not they find an interface easy to navigate.

Toggles can be used in a number of ways, but are particularly useful as part of an A/B testing process. By allowing engineers to test new features on a subset of their users without risking the entire user base, they can get more accurate feedback and understand how the feature will be used in the real world. They can then remotely turn the feature on for a small group of users and then roll it back to a previous version for the remainder of their user base.

Using a feature toggle for A/B testing can also help reduce the time it takes to test a new feature and can be a cost-effective alternative to running a full production release. This can be especially beneficial for smaller teams that don’t have the resources to run a large scale beta test.

While a feature toggle isn’t the only method to manage a new feature in production, it is one of the best and most effective approaches. Combined with a continuous delivery model and tools like Kameleon, it can be used to quickly and easily deploy and manage a broad range of different feature flags that can affect an entire user base.

Managing feature flags can be a daunting task when there are many of them, and it is often difficult to determine what changes were made to an application over time. A tool like Kameleoon can help by allowing teams to centrally manage their feature toggles, and remove old ones to reduce technical debt as the software evolves.
