Firefly is an elegant solution for personal media hosting and URL shortening. Firefly 2 is a complete rewrite of the original project.

Current status

Travis Gemnasium Coveralls Code Climate Gitter Made in Holland

Firefly 2 is still a work in progress. It's stable, but not yet feature complete and currently unreleased. You are free to use and play with HEAD, but do so at your own risk (e.g. make backups).

Getting started

Firefly is a modern ruby web application. The following you will need:

  • Ruby 2.2 or 2.3, we suggest using rbenv
  • Redis, see your system's package manager
  • Foreman, gem install foreman

Get Firefly 2

git clone
cd firefly

Install dependencies

bundle install

Create and migrate the Sqlite3 database

Firefly 2 is currently tested to work with sqlite. Support for other databases is welcome. The following will initialize a sqlite database in db/firefly_development.sqlite.

hanami db create
hanami db migrate

Start redis server

If your system is not running redis out of the box as a service, you should start it manually (do this in a separate terminal):


Run Firefly

foreman start

This will start hanami in development mode, using a local Sqlite database for storage. It will also start a Sidekiq worker for asynchronously processing data (like links and images).d

Open http://localhost:2300/admin and sign in with the development credentials: admin / admin.

Running tests

Firefly 2 is fully tested using Minitest. Running tests should alwasy be easy and straightforward:

HANAMI_ENV=test hanami db prepare
rake test

How to contribute

Your help is welcome!

Check out the open list of issues to see what features and bugs are currently open. If you're just starting out with Ruby and/or Hanami, check out the beginner friendly issues, which are great for warming up your skills.

Feel free to open a new issue to discuss your own ideas, or a pull request if you've already got something to show.

If you need any help, please hop by on Gitter to chat.

Our Responsibilities

Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.

All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
