Armadura

Armadura is a gem that lets you generate a Rails application, preconfigured with sensible defaults.

Installation

First install the armadura gem:

gem install armadura

Then run:

armadura projectname

This will create a Rails app in projectname using the latest version of Rails.

Associated services

Enable Circle CI Continuous Integration
Enable GitHub auto deploys to Heroku staging and review apps.

Gemfile

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

It includes application gems like:

Autoprefixer Rails for CSS vendor prefixes
Bourbon for Sass mixins
Bitters for scaffold application styles
Sidekiq for background processing
Flutie for page_title and body_class view helpers
High Voltage for static pages
jQuery Rails for jQuery
Neat for semantic grids
Normalize for resetting browser styles
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
Recipient Interceptor to avoid accidentally sending emails to real people from staging
Refills for “copy-paste” components and patterns based on Bourbon, Neat and Bitters
Sentry for exception notification
Simple Form for form markup and style
Skylight for monitoring performance
Title for storing titles in translations
Puma to serve HTTP requests

And development gems like:

Dotenv for loading environment variables
Pry Rails for interactively exploring objects
ByeBug for interactively debugging behavior
Bullet for help to kill N+1 queries and unused eager loading
Bundler Audit for scanning the Gemfile for insecure dependencies based on published CVEs
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
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

Armadura 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)
Configuration for Hound Continuous Integration (style)
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:

armadura app --heroku true

This:

Creates a staging and production Heroku app
Sets them as staging and production Git remotes
Configures staging with RACK_ENV environment variable 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.
Creates a Heroku Pipeline for review apps

You can optionally specify alternate Heroku flags:

armadura app \
  --heroku true \
  --heroku-flags "--region eu --addons 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:

armadura 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
armadura app --github organization/project

This has the same effect as running:

hub create organization/project

Spring

Armadura 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

Armadura requires the latest version of Ruby.

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

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.
