Node.js url.parse and Query Strings Behavior

Question

Given the URLs:

Passing through the code:

var queryData = url.parse(request.url, true).query;
if (queryData["s"]) {
    console.log("s present in hash");
} else {
    console.log("s NOT present in hash");
}

I would expect URLs 1 and 2 to test true. They do in other langs/libs I have used before. In querystring parsing code they do not treat #2 as { "s" : null } it just doesn't put s in the hash.
Is there another node package I should use if I want this behavior or another way I should be able to test for s var in the querystring?

how about if (queryData["s"] && queryData["s"].length > 0) { — Latheesan

Your variable s is in the hash. It's equal to an empty string, which is exactly what you have in your URL. When coerced into a boolean, it will evaluate as false.

> url.parse('http://somedomain.com?s=', true).query
{ s: '' }

> !!url.parse('http://somedomain.com?s=', true).query.s
false
