FAQPage Schema
How do I implement feature flags in a ZIO 2 and Scala 3 application?▼

You implement feature flags in ZIO 2 and Scala 3 by integrating the zio-openfeature libraries, which provide a comprehensive guide for controlling feature rollouts and conducting A/B testing within your applications.

Can I use LaunchDarkly or Optimizely for feature flag management with ZIO?▼

Yes, zio-openfeature supports provider integration with various feature flag platforms including LaunchDarkly, Optimizely, flagd, Flipt, Flagsmith, and Unleash for your ZIO applications.

What is the best way to set up A/B testing and experimentation in Scala 3?▼

The best way to set up A/B testing in Scala 3 is using zio-openfeature to define feature flags, configure experiments, and track results through supported providers like Optimizely or flagd.

How do I test feature flag logic in my ZIO 2 application?▼

You test feature flag logic in ZIO 2 applications using the zio-openfeature-testkit module, which provides testing utilities to evaluate flag behavior and experimentation rules before deployment.

Does zio-openfeature work with the OpenFeature Remote Evaluation Protocol (OFREP)?▼

Yes, zio-openfeature includes the zio-openfeature-ofrep module, allowing your ZIO 2 and Scala 3 applications to evaluate feature flags using the OpenFeature Remote Evaluation Protocol.

Why should I use OpenFeature standard APIs instead of vendor-specific SDKs in Scala?▼

Using OpenFeature standard APIs in Scala decouples your application logic from specific vendors, allowing you to switch between providers like LaunchDarkly, Flipt, or flagd without rewriting code.
