Simple Rails app configuration
What is this for?
Figaro is for configuring Rails 3 apps, especially open source Rails apps.
Open sourcing a Rails app can be a little tricky when it comes to sensitive configuration information like Pusher or Stripe credentials. You don't want to check private credentials into the repo but what other choice is there?
Figaro provides a clean and simple way to configure your app and keep the private stuff… private.
How does it work?
It works really well.
There are a few similar solutions out there, and a lot of homegrown attempts. Most namespace your configuration under a
Config (or similar) namespace. That's fine, but there's already a place to describe the application environment…
ENV is a collection of simple string key/value pairs and it works just great for application configuration.
As an added bonus, this is exactly how apps on Heroku are configured. So if you configure your Rails app using
ENV, you're already set to deploy to Heroku.
Give me an example.
Okay. Add Figaro to your bundle:
Next up, install Figaro:
rails generate figaro:install
This generates a commented
config/application.yml file and ignores it in your
.gitignore. Add your own configuration to this file and you're done!
Your configuration will be available as key/value pairs in
ENV. For example, here's
Pusher.app_id = ENV["PUSHER_APP_ID"] Pusher.key = ENV["PUSHER_KEY"] Pusher.secret = ENV["PUSHER_SECRET"]
How does it work with Heroku?
Heroku's beautifully simple application configuration was the inspiration for Figaro.
Typically, to configure your application
ENV on Heroku, you would do the following from the command line using the
heroku config:add PUSHER_APP_ID=8926 heroku config:add PUSHER_KEY=0463644d89a340ff1132 heroku config:add PUSHER_SECRET=0eadfd9847769f94367b heroku config:add STRIPE_API_KEY=jHXKPPE0dUW84xJNYzn6CdWM2JfrCbPE heroku config:add STRIPE_PUBLIC_KEY=pk_HHtUKJwlN7USCT6nE5jiXgoduiNl3
But Figaro provides a rake task to do just that! Just run:
Optionally, you can pass in the name of the Heroku app:
What if I'm not using Heroku?
No problem. Just add
config/application.yml to your production app on the server.
This sucks. How can I make it better?

Does Figaro have a mascot?
