feature-flags-elixir

To implement PostHog feature flags in Elixir, add the PostHog library to your mix dependencies and initialize it with your API key. You can then evaluate flags within Phoenix controllers and modules using idiomatic Elixir patterns.

The best way to control feature rollouts in Elixir is by evaluating PostHog feature flags within your modules. This approach supports environment-specific configuration, safe fallbacks, and payload support for rolling out features to user subsets.

Yes, you can use environment-specific configuration for PostHog feature flags in Elixir. The integration allows you to configure flags per environment and evaluate them with safe fallback patterns across your Elixir apps.

Server-side flag evaluation in Phoenix controllers works by checking PostHog flag states during request handling using idiomatic Elixir patterns. This allows your application to dynamically enable features or apply safe fallbacks per user subset.

You need to add the PostHog Elixir library to your mix dependencies and initialize it with your API key to enable feature flags. The Skill itself operates without external dependencies and provides framework-agnostic integration guidelines.
