Jarallax - Interactive css at your fingertips

Contribution Guides

In the spirit of open source software development, Jarallax always encourages community code contribution.

What you need to build your own Jarallax

In order to build Jarallax, you need to have Node.js/npm latest, Grunt.js and git 1.7 or later. (Earlier versions might work OK, but are not tested.)

Windows users have two options:

  1. Install msysgit (Full installer for official Git), GNU make for Windows, and a binary version of Node.js. Make sure all three packages are installed to the same location (by default, this is C:\Program Files\Git).
  2. Install Cygwin (make sure you install the git, make, and which packages), then either follow the Node.js build instructions or install the binary version of Node.js.

Mac OS users should install Xcode (comes on your Mac OS install DVD, or downloadable from Apple's Xcode site) and Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js.

Linux/BSD users should use their appropriate package managers to install make, git, and node, or build from source if you swing that way. Easy-peasy.

How to build your own Jarallax

First, clone a copy of the main Jarallax git repo by running:

git clone git://

Make sure you have grunt installed by testing:

grunt -version

Then, to get a complete, minified (w/ Uglify.js), linted (w/ JSHint) version of Jarallax, type the following:


The built version of Jarallax will be put in the bin/ subdirectory.

Git for dummies

As the source code is handled by the version control system Git, it's useful to know some features used.


The repository uses submodules, which normally are handled directly by the Makefile, but sometimes you want to be able to work with them manually.

Following are the steps to manually get the submodules:

git clone
git submodule init
git submodule update


git clone
git submodule update --init


git clone --recursive
You can’t perform that action at this time.
