Best Practices for Using Toggle in Continuous Development

Toggle is a digital trade journal highlighting the vital role technology plays in companies and organizations across the globe, as well as the men and women who make it work. We explore the unique challenges that CIOs and CTOs face, from data privacy and cybersecurity to cloud solutions and emerging applications like artificial intelligence and machine learning.

In continuous development, one of the biggest challenges is ensuring that your changes won’t cause new regressions. Using feature toggles allows developers to test changes with a small group of users before rolling them out broadly, providing valuable insights that can help mitigate the risk of new bugs. Additionally, it gives teams the flexibility to release updates in an emergency or unforeseen circumstance without requiring a red pipeline or blocking off the entire product.

Using feature toggles in your software development process can drastically improve the speed and quality of your releases. However, there are some important best practices to keep in mind. Toggle can be a powerful tool, but it’s also easy to misuse. When used improperly, it can cause confusion and chaos in a shared environment, delaying and potentially halting releases. To avoid this, it’s crucial to use them sparingly and with great care.

For instance, if your team uses static toggles, be sure to limit the scope of each toggle to the minimum necessary to complete the task at hand. Otherwise, it can be tempting to create a complex series of toggles that control large swaths of the codebase. Doing so can be confusing for other teams and lead to unintended consequences that can take weeks or even months to track down.

It’s also critical to use clear labeling for your toggles. Toggle switches should look and behave like sliders, with a visual cue to indicate their current state (on/off). They should also be clearly identified as toggles in the interface, with a clear description of what they do. Additionally, you should use standard color schemes to make it easy for all users to understand which toggles are active and which ones are not.

Aside from ensuring that toggles are clearly labeled, you should also ensure that they’re accessible to users with disabilities. For example, it’s common for designers to use colors to identify toggle states, but this can be problematic for people with color blindness or low vision who may not be able to discern the difference between green and red. To avoid this, you should use standard iconography and clear visual design to make it as easy as possible for everyone to understand what a toggle switch does.

Finally, it’s essential to maintain an accurate inventory of toggles and to prune them as soon as they’re no longer needed. This reduces the risk of accidentally deploying a feature that has been disabled by mistake, and it also helps streamline code maintenance. In addition, it’s helpful to integrate this process into your release pipeline so that you can automate the pruning of idle toggles and ensure that your codebase stays clean and tidy.
