require "time"

module StreamMessageFormatter
	def self.format(object)
		return JSON.generate(object) << "\r\n"
	end
end

get '/stream' do
	headers "Access-Control-Allow-Origin" => "*"

	stream do |out|
		while true do
			out << StreamMessageFormatter.format({time:Time.now.utc.iso8601,message:"heartbeat, baby!"})
