Ruby

Verified against provider 0.1.2 and SDK 0.3.1. Needs Ruby 3.1 or newer.

Install

gem install openfeature-ofrep-provider

Or in a Gemfile:

gem "openfeature-ofrep-provider"

Read a flag

require "open_feature/sdk"
require "openfeature/ofrep/provider"

config = OpenFeature::OFREP::Configuration.new(
  base_url: "https://flags.example.com",
  headers: { "x-api-key" => "your-read-api-key" },
)

OpenFeature::SDK.configure do |c|
  c.set_provider(OpenFeature::OFREP::Provider.new(configuration: config))
end

client = OpenFeature::SDK.build_client
ctx = OpenFeature::SDK::EvaluationContext.new(targeting_key: "user-123", "plan" => "pro")

enabled = client.fetch_boolean_value(
  flag_key: "new-checkout",
  default_value: false,
  evaluation_context: ctx,
)

The Configuration class sits directly under OpenFeature::OFREP, not under Provider, so it is OpenFeature::OFREP::Configuration. A wrong key returns the default you passed.
