Running FilterLab Locally

Git Submodules

The CodeMirror library is linked as a git submodule. After you clone the project on your machine you'll need to setup the submodules and pull in their code.

cd ./path/to/css/filterlab/
$ git submodule update --init


CSS FilterLab uses Grunt.js to concatenate and minify JavaScript & CSS resources. Grunt.js is build on nodejs, so if you don't have it already installed, go to node.js website and follow the instructions to install it. After that use the command line node package manager to install grunt.js:

$ sudo npm install -g grunt

The grunt.js project file uses other node.js modules. To quicly install all the required libraries run "npm install" in the project folder.

cd ./path/to/css/filterlab/
$ sudo npm install

You also need to make sure you have Ruby & Sass installed. If you're on OS X or Linux you probably already have them installed. Try ruby -v in your terminal. When you've confirmed you have Ruby installed, run sudo gem install sass to get Sass.

To build CSS FilterLab, you need to run the "grunt" command line tool in the project folder. This will generate the "dist/" folder.

cd ./path/to/css/filterlab/
$ grunt

File System Access

CSS FilterLab requires XHR access, but that doesn't work very well when loaded from file:// URLs. For that reason running CSS FilterLab requires serving it from a server. The easiest way to do that on a Mac would be to use python's simple server:

cd [./path/to/css/filterlab]/dist/
python -m SimpleHTTPServer

Open http://localhost:8000 in your browser.
