base64 encoding images in NodeJS

img2data.js

/*
 * Complete reworking of JS from https://gist.github.com/803410 
 * Removes external `request` dependency
 * Caveats:
 *  * No error checking
 *  * Largely a POC. `data` URI is accurate, but this code cannot simply be inserted into an `express` app

var URL = require('url'),
    sURL = 'http://nodejs.org/logo.png',
    oURL = URL.parse(sURL),
    http = require('http'),
    client = http.createClient(80, oURL.hostname),
    request = client.request('GET', oURL.pathname, {'host': oURL.hostname})

request.end();
request.on('response', function (response)
{
    var type = response.headers["content-type"],
        prefix = "data:" + type + ";base64,",
        body = "";

    response.setEncoding('binary');
    response.on('end', function () {
        var base64 = new Buffer(body, 'binary').toString('base64'),
            data = prefix + base64;
        console.log(data);
    });
    response.on('data', function (chunk) {
        if (response.statusCode == 200) body += chunk;

});

Cool, this is the first example of doing this I've found that works. Thanks!
