Flagship

Flagship acts as an interface and tooling for working with launchdarkly feature flags.

Installation

The package can be installed by adding flagship to your list of dependencies in mix.exs:

def deps do
  [
    {:flagship, "~> 0.1.6"}
  ]
end

Start up the application (in your application.ex file):

children =
  [
    {Flagship.FeatureFlags, name: Flagship.FeatureFlags},
    ...
  ]

And configure the application (in config.exs or similar):

config :flagship,
  ld_sdk_key: "<ENTER SDK KEY HERE>", # required
  default_context: %{}, # optional - expects a map that represents a launchdarkly context (https://docs.launchdarkly.com/home/contexts)
  ld_client_options: %{ # all values are optional
    file_datasource: true,
    send_events: false,
    file_paths: ['launch_darkly_local_config.json'],
    feature_store: :ldclient_storage_map,
    file_auto_update: true,
    file_poll_interval: 1000
  }

And configure for your test environment (in text.exs):

config :flagship,
  ld_sdk_key: "test key",
  ld_client_options: %{
    datasource: :testdata,
    send_events: false,
    feature_store: :ldclient_storage_map
  }

Running tests on this project

The tests rely on a test double for the LaunchDarkly implementation.
