Gemfile

If you bundle added all of your gems and ran bundle install your gem file will look similar to this:

gem "sinatra", "~> 2.0"

gem "sinatra-activerecord", "~> 2.0"

gem "activerecord", "~> 6.0"

gem "sqlite3", "~> 1.4"

gem "pry", "~> 0.13.1"

gem "require_all", "~> 3.0"

Gemfile.lock

This file should have been auto-generated after running bundle install . It should have all of your gem specs.

environment.rb

"SINATRA_ENV" is the key to Ruby’s ENV hash and defines your deployment environment, configures our database, and requires all the files in our app.

ENV['SINATRA_ENV'] ||= "development"

require 'bundler/setup'
Bundler.require(:default,ENV['SINATRA_ENV'])

configure :development do
  set :database, {adapter: 'sqlite3', database: "db/database.sqlite3"}
end

require_all 'app'

application_controller.rb

class ApplicationController < Sinatra::Base

  set :views, -> {File.join(root, "../views")}

  get '/' do
    erb :index
  end

end

layout.erb

<html>
  <head>
    <meta charset="UTF-8">
    <title>title</title>
  </head>
  <body>
    <div class="container">
      <%= yield %>
    </div>
  </body>
</html>

Rakefile

Your Rakefile should be requiring your environment and if you want to be able to run pry in your rake console you should have the following in your rake file:

require_relative './config/environment'

require 'sinatra/activerecord/rake'

desc "Starts console"
task :console do
  Pry.start
end

Now you should be able to run shotgun in your terminal and head over to http://localhost:9393/ in your browser and you should see "Hello".

Next step will be to set up our database by using rake. If you want to browse the rake commands run rake -T in your console.
