Matthieu Aussaguel a web developer working at Envoto, releasing MiniJs plugins.
MiniJs is a free and open source suite of jQuery plugins that are written in CoffeeScript.
The plugins are perfect for everyday-use and include: slider, tooltip, notification, Twitter feed and counter (new ones are on the way).
They are all built with simplicity in mind and very easy-to-use with only few important parameters.
Also, for CoffeScript developers, a MiniBoilerplate is provided for developing new jQuery plugins faster.
