Cordova hook that uglifies and minifies your app's Javascript, CSS and HTML files, as well as compresses your image files. It is a modification of the work of Ross Martin's original cordova-uglify and Alastair Paragas' modified version, with the added default parsing of your top-level app folder www as well as minifying of HTML files.
This DOES NOT compress the assets in your www folder, but rather, on your respective platform's www folders, so your development environment isn't touched, and your apps stay fast and slim!
Install this package inside of your app's root folder with this command.
npm install cordova-minify-v2 --save-dev
The --save-dev flag is important! If you decide to work on another environment, cordova-minify cannot run without the original package and its dependencies! After install, an after_prepare folder will be added to your hooks folder with the cordova-minify-v2.js script in it.
Once you have this hook installed it will compress your app's JavaScript and CSS when you run a cordova prepare <platform> or cordova build <platform> command. This hook does not change your assets that live in the root www folder; it will uglify the assets that get outputted to the platforms folder after a prepare or build.
By default the hook will uglify the JavaScript, CSS, HTML, and images in the <platform> www/js, www/css, www/img, www/javascript, www/style, www/html, and www/media folders of your project recursively (If they exist) as well as the top-level www folder (not recursively) to account for minifying the index.html and any other files that may reside there.
Take a look at this line in the hook to add more folders to be minified - optional.
You can configure the hook to uglify/minify only for a release build, see here.
If you would like to have verbose logging, set debug to true here.
To disable parsing of the www folder, set processRoot to false here.
Options for HTML minification can be changed here and a list of all available options can be found here.
Javascript uglify options can be changed here and a list of all available options can be found here scattered throughout the page.
CSS minification options can be changed here and a list of all available options can be found here.
Out of the box this hook requires Cordova 3.3.1-0.4.2 and above but it can work with versions 3.0.0 thru 3.3.0 if you manually indicate the path for the platforms directories on Android and iOS see here. This is because the CORDOVA_PLATFORMS environment variable was not added until version 3.3.1-0.4.2 (see this post by Dan Moore).
