# Read-only Adapter

> A read-only adapter for Flipper.

Use this adapter to wrap another adapter and raise an exception for any writes.

Any attempted write raises `Flipper::Adapters::ReadOnly::WriteAttempted`  with message  `'write attempted while in read only mode'`

## Usage

```ruby
# example wrapping memory adapter
require 'flipper/adapters/read_only'

Flipper.configure do |config|
  config.use Flipper::Adapters::ReadOnly
end

# Enabling a feature
> Flipper[:dashboard_panel].enable
=> Flipper::Adapters::ReadOnly::WriteAttempted: write attempted while in read only mode
```
