Firefly supports QR Codes. The QR Code contains the original short URL, so when scanned people will open the short URL and be redirected to the target web site.

Enabling QR Code support

As of version 1.2.0 of Firefly, QR Code support is disabled by default. If you want to use QR Codes install the following gems:

  • barby
  • png

Or, add them to your Gemfile:

gem 'barby'
gem 'png'

When Firefly is able to load those gems, QR Code support will be enabled automatically (you may need to restart your server, though).

How to use QR Codes

Using QR Codes is simple. Given you have a short URL, like http://aj.gs/5 you can get the QR Code by adding the extension .png to the URL.

http://aj.gs/5 => http://aj.gs/5.png

An example:

http://aj.gs/5.png
