OpenFeatureRulestead (open_feature_rulestead v1.0.0)

Copy Markdown View Source

OpenFeature provider for Rulestead — evaluate feature flags through the standard OpenFeature SDK backed by Rulestead.Runtime's deterministic, auditable evaluation engine.

Use this package when your host application already uses the Elixir open_feature SDK and wants OpenFeature evaluations to resolve through Rulestead instead of a custom provider adapter.

Install

Add the OpenFeature SDK and the Rulestead provider companion to your mix.exs:

defp deps do
  [
    {:open_feature, "~> 0.1.3"},
    {:open_feature_rulestead, "~> 1.0"}
  ]
end

Then fetch dependencies:

mix deps.get

Your host application is still responsible for configuring and booting rulestead itself. This companion only provides the OpenFeature provider layer.

Provider setup

Initialize the provider with an OpenFeature domain matching the Rulestead environment you want to evaluate against:

provider = %OpenFeatureRulestead.Provider{}
{:ok, provider} =
  OpenFeatureRulestead.Provider.initialize(provider, "production", %{})
OpenFeature.set_provider(provider, domain: "production")
