stay_awake

stay_awake requests websites periodically. It's written especially for Heroku, that puts applications to sleep when there are no requests coming in.

$ gem install stay_awake

gem 'stay_awake'

gem 'stay_awake', :github => 'tbuehlmann/stay_awake'

buzzer = StayAwake.configure do |c|
  c.app_name = 'app_name'
end

buzzer.buzz

Put the StayAwake.configure block inside Sinatra's configure block, run buzz and you're done:

# app.rb

class App < Sinatra::Base
  configure :production do
    StayAwake.configure do |c|
      c.app_name = 'app_name'
    end.buzz
  end

  # …
end

Put the StayAwake.configure block inside an initializer, run buzz and you're done:

# config/initializers/stay_awake.rb

if Rails.env.production?
  StayAwake.configure do |c|
    c.app_name = 'app_name'
  end.buzz
end

You can either use app_name or url, but url has precedence over app_name. If just app_name is given, it will be translated to http://app_name.herokuapp.com/.

strategy takes a single Class or Array of Classes that mixed in the Strategy Module. If an Array is given, each Strategy is tested for availability. The first available Strategy will be used for buzzing.

When using EM-HTTP-Request, the buzzing will begin on the next_tick. When using httparty or Net::HTTP, buzzing will begin immediately (using a Thread).
