flipper

A light-weight library providing an interface for minimally obtrusive feature toggles.

This library provides the main user interface and an in-memory feature flag storage adapter.

Persisted storage adapters (think Postgres, Redis, etc) will be created as separate packages.

This library is heavily inspired by @jnunemaker's work on Ruby's Flipper. Thanks for paving the way!

Installation

Add feature-flipper to your cabal file, then import Control.Flipper into your module.

Usage examples

• Configuring feature flags from environment variables

Roadmap
