Sinatra is a DSL for quickly creating web applications in Ruby with minimal effort.
If you already have a sinatra app, use it or go ahead and create one and add below code which basically has sinatra routes.
#web.rb
get '/' do
'Hey there!'
end
You need a Procfile file alongside your config.ru to tell Heroku how to run your app.
Example content of Procfile
web: bundle exec ruby web.rb -p $PORT
What this says is that run a web process on the port Heroku gives you using the bundle environment.
Sample config.ru
$:.unshift File.expand_path("../", __FILE__)
require 'rubygems'
require 'sinatra'
require './web
run Sinatra::Application
-
Array#unshift will prepend the new path to $:
-
File#expand_path is considered to be Ruby idiom for getting the absolute path to a file when you know the path relative to the current file.
Voila!
Keep Coding !!!
