> Feature flipping is the act of enabling or disabling features or parts of your application, ideally without re-deploying or changing anything in your code base.

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  flipper:
    github: metaware/flipper
```

## Usage

```crystal
require "flipper"
```

```
Flipper.adapter = Kiwi::MemoryStore.new
Flipper.adapter = Kiwi::RedisStore.new(Redis.new)
```

You are free to use anyone of the supported adapeters/stores from [crystal-kiwi](https://github.com/greyblake/crystal-kiwi)

```crystal
Flipper.enable(:feature_name)

if Flipper.enabled?(:feature_name)
  puts "Feature launched, Let's roll!"
else
  puts "Feature not released yet."
end

Flipper.disable(:search)

if Flipper.disabled?(:search)
  puts "Search is not available yet!"
end
```
