Deploy Sinatra app on Heroku

Question

I have simple Sinatra app.

web.rb:

require \'sinatra\'

get \'/\' do 
    \"Hello\" 
end

Gemfile:*

Answer 1

As an update, here is a slightly more minimal app that I created, and confirmed to be working as of today. The thin gem was not needed, and a Procfile was not needed to get an initial working app.

Gemfile

source 'https://rubygems.org'
gem 'sinatra'

config.ru

require './app'

run Sinatra::Application

Note: The require line uses './app' instead of 'app'.

app.rb

require 'sinatra'

get '/' do
  'Hello, World! Find me in app.rb'
end

If you want to use this template, you can copy it, bundle, and push the Git repo.

$ git init
$ git add .
$ git commit -m "initial sinatra app"
$ bundle
$ git add Gemfile.lock
$ git commit -m "bundle install"
$ heroku create
$ git push heroku master
$ heroku open
