Using in a Node.js Application

To run CSS Lint from within a Node.js application use the following:

var cssLint = require('csslint').CSSLint;
var result = cssLint.verify("h1 { color: red; }");
if (result.messages.length === 0) {
    //Success
} else {
    //Errors or warnings
    for (i=0; i<result.messages.length; i++) {
        var message = result.messages[i];
        console.log("%s (line %d, col %d): %s", message.type, message.line, message.col, message.message);
    }
}
