Using jade template to render rss-feed in nodejs

rss.jade

doctype xml
rss(version='2.0')
    channel
        title= feed.title
        description= feed.description
        link= feed.link
        language= feed.en
        for item in posts
            item
                title= item.title
                pubDate= item.pubDate
                description= item.description
                link= item.canonicalUrl
                    

rss.js

var fs = require('fs');
var jade = require('jade');
var html = fs.readFileSync('./rss.jade').toString();
var options = {
  feed: {
    title: 'feed title',
    description: 'feed description',
    link: 'http://example.org/rss.xml',
    language: 'en'
  },
  posts: [{
    title: 'post1 title',
    description: 'post1 summary',
    canonicalUrl: 'http://example.org/post1',
    pubDate: (new Date()).toGMTString()
  }]
};
jade.render(html, options, function (err, html) {
  if (err) {
    throw err;
  }
  console.info(html);
});
