Plug

A Rails engine to turn on/off features (Feature flipper).

Features

• Supports Rails 3 and above
• MySQL
• Set notices

Prerequisites

• Rails version 3 and above
• MySQL

Getting Started

Add this line to your application's Gemfile:

gem 'plug'

Execute:

→ bundle

And run the install generator:

→ rails g plug:install
→ rails g plug:install:migrations
→ rails db:migrate # Newer version of Rails
→ rake db:migrate # Older version of Rails
→ rails s

Usage

Go to localhost:3000/plug and start creating features.

Use the provided method to check if the feature is enabled.

Plug.enabled?('my-awesome-feature-slug')

If you wanted to restrict routes, you can use Plug::Constraint class

Rails.application.routes.draw do
  resources :blog, constraint: Plug::Constraint.new('my-awesome-feature-slug')
end

Notices can be displayed using the Plug.notice method.

<%= Plug.notice('my-awesome-feature-slug') %>

If you have custom HTML for notice, you can pass a block.

<% Plug.notice('my-awesome-feature-slug') do |notice| %>
  <div class="alert">
    <p><%= notice %></p>
  </div>
<% end %>

Running the tests

→ bundle exec rspec spec

Publishing to rubygems.org

Make sure to bump the version. Rubygems don't accept version overrides.

→ gem build plug.gemspec
→ gem push plug-<version>.gem

TODOs

• Ability to disable all features using one button
• Add screenshot
• Allow block parameters for enabled? method
