Challenge 2. You should generate users.json from http://www.json-generator.com/

challenge2.js

// responds to /users (returns users)
// post to { me: 'name', oldest: oldestId } to /oldest (checks against the oldest)

var http    = require('http'),
    url     = require('url'),
    users   = require('./users.json'),
    options = { port: 8000 },
    oldest  = users[0];

for (var i in users) {
    if (users[i].age > oldest.age ) {
        oldest = users[i];
    }
}
//console.log('oldest: ', JSON.stringify(oldest));

function checkOldestUser (req, res) {
    var obj, data = '';
    
    req.on('data', function (d) { data += d.toString(); });

    req.on('end', function(){
        obj = JSON.parse(data);

        if(typeof obj.me !== 'undefined' && obj.oldest === oldest.id){
            res.write(obj.me+' figured it out!  Good job!  Fireworks and celebrations for you');
        } else if (obj.oldest === oldest.id) {
            res.write('Someone found the oldest user but didn\'t provide a name. Try again!');
        } else if (typeof obj.me !== 'undefined') {
            res.write('Getting closer '+obj.me+'... try again!');
        } else {
            res.write('Not quite... try again!');
        }
        
        res.end();
    });
}

var server = http.createServer(function (req, res) {
    res.statusCode = 200;

    if (req.url === '/users') {
        res.write(JSON.stringify(users));
        res.end();
    } else if (req.url === '/oldest' && req.method === 'POST') {
        checkOldestUser(req,res);
    } else {
        res.write('Not a valid route, try again!' + req.method);
        res.end();
    }
}).listen(options.port, function onStart () {
    console.log('server started on port %s', options.port);
});
