Answer 2

You could use guard-rack. Lifted from an article at dblock.org:

Add this to your Gemfile:

group :development do
  gem "guard"
  gem "guard-bundler"
  gem "guard-rack"
end

Then, create a Guardfile at the root of your project with this content:

guard 'bundler' do
  watch('Gemfile')
end

guard 'rack' do
  watch('Gemfile.lock')
  watch(%r{^(config|app|api)/.*})
end

Lastly, run Guard, like so: bundle exec guard, and rackup will reload every time.

Answer 3

gem install sinatra-reloader

require 'sinatra/base'
require "sinatra/reloader"

class MyApp < Sinatra::Base
  register Sinatra::Reloader

  get '/' do
    "Hello Testing1!"
  end
end

You may want to set environment variable to development and conditionally load the gem.
