Cordova hook that allows you to uglify or minify your apps JavaScript and CSS. It is using UglifyJS2 for JavaScript compression and clean-css to minify CSS. The hook also supports compressing your apps images using imagemin.
Install the following package below inside of your apps root folder.
npm install cordova-uglify
After install an after_prepare folder will be added to your hooks folder with the uglify.js script in it. A JSON config file (uglify-config.json) for the script will be added to the hooks folder.
Once you have this hook installed it will compress your apps 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 output to the platforms folder after a prepare or build. By default the hook will uglify the JavaScript and minify CSS files by recursively searching your projects www folder. You can disable the recursive search by setting the recursiveFolderSearch to false in the JSON config file. If you want to process files only when building/preparing for release include --release in your CLI command like this - cordova prepare ios --release.
{
"alwaysRun": false, // set to true to always uglify files
"recursiveFolderSearch": true, // process all JS and CSS files found in www
"foldersToProcess": [ // when recursiveFolderSearch is set to false only files in these directories will be processed
"js",
"css",
"img"
],
"uglifyJsOptions": { // pass options to UglifyJS2 (you can include more than these below)
"compress": {
"drop_console": true
},
"fromString": true
},
"cleanCssOptions": { // pass options to CleanCSS (you can include more than these below)
"noAdvanced": true,
"keepSpecialComments": 0
},
"imageminOptions": { // pass options to imagemin (you can include more than these below)
"jpeg": {
"progressive": true,
"arithmetic": false
},
"png": {
"optimizationLevel": 2
},
"gif": {
"interlaced": false
},
"svg": {
"pretty": false
}
}
}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. This is becuase the CORDOVA_PLATFORMS environment variable was not added until version 3.3.1-0.4.2 (see this post by Dan Moore).
I came across a quirk on OSX and Linux where the hooks folder needs to have permissions modified. Perform a chmod -R 755 hooks to resolve this issue.
