Jumpstart 
Jumpstart is the base Rails application used at thoughtbot.

Installation
First install the jumpstart gem:
gem install jumpstart
Then run:
jumpstart projectname
This will create a Rails app in projectname using the latest version of Rails.
Gemfile
To see the latest and greatest gems, look at Jumpstart' Gemfile, which will be appended to the default generated projectname/Gemfile.
It includes application gems like:
- Airbrake for exception notification
- Bourbon for Sass mixins
- Bitters for scaffold application styles
- Delayed Job for background processing
- Email Validator for email validation
- Flutie for and
body_classview helper - High Voltage for static pages
- jQuery Rails for jQuery
- Neat for semantic grids
- New Relic RPM for monitoring performance
- Normalize for resetting browser styles
- Postgres for access to the Postgres database
- Rack Timeout to abort requests that are taking too long
- Recipient Interceptor to avoid accidentally sending emails to real people from staging
- Simple Form for form markup and style
- Title for storing titles in translations
- Unicorn to serve HTTP requests
And development gems like:
- Dotenv for loading environment variables
- Pry Rails for interactively exploring objects
- ByeBug for interactively debugging behavior
- Spring for fast Rails actions via pre-loading
And testing gems like:
- Capybara and Capybara Webkit for integration testing
- Factory Girl for test data
- Formulaic for integration testing HTML forms
- RSpec for unit testing
- RSpec Mocks for stubbing and spying
- Shoulda Matchers for common RSpec matchers
- Timecop for testing time
Other goodies
Jumpstart also comes with:
- The
./bin/setupconvention for new developer setup - Rails' flashes set up and in application layout
- A few nice time formats set up for localization
Rack::Deflaterto compress responses with Gzip- A low database connection pool limit
- Safe binstubs
- t() and l() in specs without prefixing with I18n
- An automatically-created
SECRET_KEY_BASEenvironment variable in all environments. - Configuration for Travis Pro continuous integration.
- The analytics adapter Segment.io (and therefore config for Google Analytics, Intercom, Facebook Ads, Twitter Ads, etc.).
Heroku
You can optionally create Heroku staging and production apps:
jumpstart app --heroku true
This:
- Creates a staging and production Heroku app
- Sets them as
stagingandproductionGit remotes - Configures staging with
RACK_ENVandRAILS_ENVenvironment variables set tostaging - Adds the Rails 12 Factor gem to make running Rails 4 apps easier on Heroku
Git
This will initialize a new git repository for your Rails app. You can
bypass this with the --skip-git option:
jumpstart app --skip-git true
GitHub
You can optionally create a GitHub repository for the suspended Rails app. It requires that you have Hub on your system:
curl http://hub.github.com/standalone -sLo ~/bin/hub && chmod +x ~/bin/hub
jumpstart app --github organization/project
This has the same effect as running:
hub create organization/project
Dependencies
Jumpstart requires the latest version of Ruby.
Some gems included in Jumpstart have native extensions. You should have GCC installed on your machine before generating an app with Jumpstart.
Use OS X GCC Installer for Snow Leopard (OS X 10.6).
Use Command Line Tools for XCode for Lion (OS X 10.7) or Mountain Lion (OS X 10.8).
We use Capybara Webkit for full-stack JavaScript integration testing. It requires QT. Instructions for installing QT are here.
PostgreSQL needs to be installed and running for the db:create rake task.
