Gruntfile.js

/**
 * Gruntfile for Known project.
 * 
 * This is a grunt task for building various aspects of Known. You'll only need to 
 * use this if you're a developer working on the core.
 * 
 * Installation
 * 
 *  - npm i 
 * 
 * Useful tasks:
 * 
 *  - grunt - builds everything
 *  - grunt build-lang - recompiles gettext corpus (make sure you composer install before hand to get the build scripts!)
 *  - grunt build-css - Compile the SASS
 *  - grunt build-js - minify javascript and pass it through babel
 *  - grunt test - lint your js and css
 *  - grunt watch - look for changes and recompile as needed (useful for development)
