Wheel 🛞

A Rails engine for managing dynamic configuration and feature flags with conditional rules.

It's time for you to take the wheel.

• Dynamic Configuration Storage

  • Store and manage configuration values with type safety
  • Supported types: string, integer, float, boolean, and JSON
  • In-memory caching for fast access
  • Real-time configuration updates

• Conditional Rules

  • Define rules based on context attributes
  • Supported operators: equals, not_equals, in, not_in, matches, greater_than, less_than
  • Multiple conditions per configuration
  • Context-based evaluation

• Web Interface

  • Modern UI for managing configurations
  • Create and edit configuration values
  • Define conditional rules
  • Type-safe value editing

1. Add to your Gemfile:

gem 'wheel'

2. Install:

$ bundle install

3. Run the installer:

$ rails generate wheel:install
$ rails db:migrate

4. Mount the engine in config/routes.rb:

Rails.application.routes.draw do
  mount Wheel::Engine => "/wheel"
end

# Get a configuration value
value = Wheel["feature.enabled"]

# Get a configuration with context
value = Wheel["pricing.tier", user_id: "123"]

You can define default context attributes:

# config/initializers/wheel.rb
Wheel.configure do |config|
  config.attributes = {
    user_id: {
      name: 'User ID',
      description: 'The unique identifier of the user'
    }
  }
end

1. Fork the repository
2. Create your feature branch (git checkout -b feature/my-feature)
3. Commit your changes (git commit -am 'Add my feature')
4. Push to the branch (git push origin feature/my-feature)
5. Create a Pull Request
