Install the module:
npm install grunt-yui-compressor
Then add this line to your project’s
Now you can specify CSS/JS files to minify. Here’s a basic example:
'min':'dist':'src': 'src/foo.js' 'src/bar.js''dest': 'build/foobar.min.js''cssmin':'dist':'src': 'css/foo.css' 'css/bar.css''dest': 'build/foobar.min.css'
cssmin use the same API as the built-in
This plugin does two things:
- It overrides grunt’s built-in
mintask, and makes it use YUI Compressor instead of UglifyJS.
- It provides a
cssmintask that uses YUI Compressor to compress CSS files.
Both these tasks are multi tasks, meaning that each of them will implicitly iterate over all of its targets if no target is specified.
min task relies on UglifyJS. I love UglifyJS, but it has a few annoying issues and shortcomings:
- It strips license comments of the form
/*! foo */, only preserving the first comment in the concatenated file. This may cause you to violate licenses of open-source libraries that you’re using in your projects.
- It doesn’t escape non-printable ASCII characters in the output, potentially leading to hard-to-debug issues. Try minifying
'\x0b', for example.
- There’s no way to make UglifyJS not munge a variable name.
YUI Compressor doesn’t have these issues.
