Fire and forget http request with em-http-request ruby gem

client.rb

# You just need to set inactivity_timeout = 0.1 (or any other low number except zero).
# It will trigger the request and wait only 0.1 second for the response. You don't need to define the callbacks as well.
# Example code below:

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem "em-http-request"
end

require "eventmachine"
require "em-http-request"

EM.run do
  options = {:inactivity_timeout => 0.1}
  http = EM::HttpRequest.new("http://localhost:4567", options).get

  # http.callback do
  #   puts "Success."
  #   p http.response
  # end

  # http.errback do
  #   puts "Error."
  # end

  puts "Sent."
end

server.rb

# the server will complete processing the request even though it takes more than 0.1s

require 'sinatra'

get '/' do
  sleep 5

  p 'Put this in your pipe & smoke it!'
end
