Decoding URL encoded characters in Node.js

Question

I'm sending a cookie back using res.cookie(JSON.stringify({foo: "bar"}), and when I look at the received cookie, the value I'm seeing is %7B%22foo%22%3A%22bar%22%7D. How do I decode this in a Javascript environment such as node.js?

nodejs.org/api/…

you can use decodeURIComponent or decodeURI

@Tushar, thanks. I saw Miro's comment which led me to querystring :) Here's how I was able to decode the above:

var cookieValue = "%7B%22foo%22%3A%22bar%22%7D";
querystring.unescape(cookieValue);
//=> '{"foo":"bar"}'
JSON.parse(querystring.unescape(cookieValue));
//=> {foo: 'bar'}
