Examples

Comments

If you'd like to preserve comments (for licensing for example), then you can specify a function to do this like so:

minify({
  output: {
    comments: function(node, comment) {
        var text = comment.value;
        var type = comment.type;
        if (type == "comment2") {
            // multiline comment
            return /@preserve|@license|@cc_on/i.test(text);
        }
    }
  }
});
