RailsThrottle

RailsThrottle is a simple library used to throttle code in your Rails application.

Add this line to your application's Gemfile:

gem "rails_throttle", "~> 0.2.0"

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_throttle

• See full documentation here: https://www.rubydoc.info/gems/rails_throttle/0.4.0/RailsThrottle/Throttle
• Example configuration (for production, you can configure other environments in a similar way):

  # In config/environments/production.rb
  RailsThrottle.backend = ActiveSupport::Cache::RedisStore.new "localhost:6379/0"
  
  # Alternatively, also supports any of the other caching strategies of ActiveSupport::Cache.
  # For details, see https://api.rubyonrails.org/classes/ActiveSupport/Cache.html.

• Example usage:

  RailsThrottle::Throttle.increment("foo", limit: 4, period: 2.seconds) # => 1
  RailsThrottle::Throttle.increment("foo", limit: 4, period: 2.seconds) # => 2
  RailsThrottle::Throttle.decrement("foo", period: 2.seconds) # => 1
  RailsThrottle::Throttle.reset("foo")
  RailsThrottle::Throttle.increment("foo", limit: 4, period: 2.seconds, increment: 4) # => 4
  RailsThrottle::Throttle.increment("foo", limit: 4, period: 2.seconds) # => RailsThrottle::ThrottleError
  RailsThrottle::Throttle.throttled?("foo", limit: 5) # => true
  
  # ... wait 2 seconds ...
  
  RailsThrottle::Throttle.throttled?("foo", limit: 5) # => false

Just the usual clone and bundle to install dependencies. Run rake test to run tests.
