NOTE: Underwear is under heavy and frequent development and is not recommeded for use yet.

Underwear is based on Suspenders, the base Rails application used at thoughtbot.

Installation

First install the underwear gem:

gem install underwear

Then run:

underwear projectname

This will create a Rails app in projectname using the latest version of Rails. Note: This will also create Heroku staging and production apps using the name you provide, so make it unique.

Gemfile

To see the latest and greatest gems, look at Underwear' Gemfile, which will be appended to the default generated projectname/Gemfile.

It includes application gems like:

• AASM for state machines for Ruby classes
• Autoprefixer Rails for CSS vendor prefixes
• Awesome Print Pretty print your Ruby objects with style
• Devise Flexible authentication solution.
• FriendlyId FriendlyId is the "Swiss Army bulldozer" of slugging and permalink plugins for Active Record.
• jQuery Rails for jQuery
• New Relic RPM for monitoring performance
• Paperclip Easy file attachment management for ActiveRecord.
• Postgres for access to the Postgres database
• Rack Canonical Host to ensure all requests are served from the same domain
• Rack Timeout to abort requests that are taking too long
• Raven (Sentry) for exception notification
• Recipient Interceptor to avoid accidentally sending emails to real people from staging
• Semantic UI UI component framework based around useful principles from natural language.
• Sidekiq for background processing
• Puma to serve HTTP requests

And development gems like:

• Bullet help to kill N+1 queries and unused eager loading
• Bundler Audit for scanning the Gemfile for insecure dependencies based on published CVEs
• ByeBug for interactively debugging behavior
• Dotenv for loading environment variables
• Faker A library for generating fake data such as names, addresses, and phone numbers.
• Pry Rails for interactively exploring objects
• Spring for fast Rails actions via pre-loading
• Web Console for better debugging via in-browser IRB consoles.

And testing gems like:

• Capybara and Capybara Webkit for integration testing
• Factory Girl for test data
• RSpec Rails RSpec for Rails-3+
• RSpec Mocks for stubbing and spying
• Shoulda Matchers for common RSpec matchers

TODO

• Database Cleaner Strategies for cleaning databases in Ruby.
• Webmock Library for stubbing and setting expectations on HTTP requests in Ruby.
• VCR Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests.
• Simplecov Code coverage for Ruby 1.9+ with a powerful configuration library and automatic merging of coverage across test suites.

Other goodies

Underwear also comes with:

• The ./bin/setup convention for new developer setup
• The ./bin/deploy convention for deploying to Heroku
• Rails' flashes set up and in application layout
• A few nice time formats set up for localization
• Rack::Deflater to 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_BASE environment variable in all environments
• Configuration for CircleCI Continuous Integration (tests)
• The analytics adapter Segment (and therefore config for Google Analytics, Intercom, Facebook Ads, Twitter Ads, etc.)

Heroku

You can optionally create Heroku staging and production apps:

underwear app --heroku true

This:

• Creates a staging and production Heroku app
• Sets them as staging and production Git remotes
• Configures staging with RACK_ENV and RAILS_ENV environment variables set to staging
• Adds the Rails Stdout Logging gem to configure the app to log to standard out, which is how Heroku's logging works.

You can optionally specify alternate Heroku flags:

underwear app \
  --heroku true \
  --heroku-flags "--region eu --addons newrelic,sendgrid,ssl"

See all possible Heroku flags:

heroku help create

Git

This will initialize a new git repository for your Rails app. You can bypass this with the --skip-git option:

underwear 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
underwear app --github organization/project

This has the same effect as running:

hub create organization/project

Spring

Underwear uses spring by default. It makes Rails applications load faster, but it might introduce confusing issues around stale code not being refreshed. If you think your application is running old code, run spring stop. And if you'd rather not use spring, add DISABLE_SPRING=1 to your login file.

Dependencies

Underwear requires the latest version of Ruby.

Some gems included in Underwear have native extensions. You should have GCC installed on your machine before generating an app with Underwear.

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.
