Plug Maintainability

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

Features

  • Manage features with notices
  • Manage site notices with themes

Prerequisites

  • Rails version 5 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 plug:install:migrations
→ rails db:migrate
→ 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 %>

Buttons

Add buttons to the config block to perform rake tasks from the plug dashboard

  config.buttons = [
    { label: 'Clear cache', task: 'tmp:cache:clear' }
  ]

Themes

Themes can be added in Site Notices. Themes are just string stored in the database. You still need to style the theme.

By default, we have default and dark in config/plug.rb. Below is an example on how you can utilise the theme string.

- theme_class = "site-notice--#{site_notice.theme}"

.site-notice{ class: theme_class }
  %p My site notice
// BEM
.site-notice {
  @include modifier('default') {
    ...
  }
  
  @include modifier('dark') {
    ...
  }
}

Creating new migrations

→ rails g migration MyAwesomeMigration
→ rails g model MyModel name:string slug:string:index
→ rails db:migrate
→ rails db:migrate RAILS_ENV=test
→ rake plug:install:migrations # Run this on the app to copy the new migrations

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
  • Versioning of features
  • History of feature activities
