How does feature toggle work?

Feature toggles are an important technique for continuous delivery. The technique allows developers to release a version of a product that has unfinished features. These unfinished features are hidden (toggled) so that they do not appear in the user interface.

How does a feature flag work?

Summary: Feature flagging (also commonly known as feature toggling) is a software engineering technique that turns select functionality on and off during runtime, without deploying new code. Feature flags, also known as “toggles”, “bits”, “flippers”, or “switches” allow you to do this and more.

How do you set a feature flag?

Feature flags help reduce risk, allowing you to do controlled testing, and separate feature delivery from customer launch….Create a user list

1. In your project, navigate to Deployments > Feature Flags.
2. Select View user lists.
3. Select New user list.
4. Enter a name for the list.
5. Select Create.

How do you implement a feature flag in Python?

Steps

1. Create a Python Flask Application. If you already have a Python Flask application feel free to skip to step 2.
2. Setup the Feature Flag Interface. Create a free Optimizely Rollouts account here.
3. Install the Optimizely Python SDK.
4. Implement the Feature Flag.
5. Turn the Feature Toggle on!

Do feature toggles scale?

Feature flagging enhances continuous delivery and continuous integration by making “continuous” more achievable. With continuous delivery and feature flag management, a team can launch, control, and measure their features at scale.

What’s the difference between feature flags and feature toggles?

Feature Toggles are also refered to as Feature Flags, Feature Bits, or Feature Flippers. These are all synonyms for the same set of techniques. Throughout this article I’ll use feature toggles and feature flags interchangebly.

How are feature flags used in software development?

Feature toggles —sometimes called feature flags— are a method for modifying features at runtime without modifying code. Developers can create feature toggles by coding a “decision point” where the system runs a given feature depending on whether specified conditions are met.

How are feature toggles used in continuous integration?

Feature toggles are among the most powerful methods to support continuous integration and continuous delivery (CI/CD). Feature toggles —sometimes called feature flags — are a method for modifying features at runtime without modifying code.

What’s the best way to make a toggle work?

Have the Toggle Router make decisions based on a Toggle Configuration , and make that configuration environment-specific. Only turn the new feature on in a pre-production environment. Allow Toggle Configuration to be modified at runtime via some form of admin UI. Use that admin UI to turn the new feature on a test environment.
