log post and get parameters in nodejs

Question

I'm trying to make simple logger for nodejs to handle post and get request also, but I've got problem, because of the non blocking feature of node-js, the parameters is print after the system print the response log here is my code

process.stdout.write(createReqFormat(req));

if(req.method !== 'GET') {
  var form = new formidable.IncomingForm();
  form.parse(req, function(err, fields, files){
    process.stdout.write('\n Parameters:' + util.inspect(fields));
  });
}

res.on('finish', function(){
  process.stdout.write(createResFormat(res));
});
next();

for now I only print parameter for post parameter, but this already killing me.

Started POST /post for 127.0.0.1 at Mon Apr 27 2015 09:08:36 GMT+0700 (WIB)
Completed 200 OK
Parameters:{ one: '1', kals: '123', test: '1233', 'test[123]': 'dfjksdjf' }

how to make it print in the right order?

thank you

Can you put the entire code for your request handler?

Parsing the form can actually take more time than finishing the response, so don't call next (or res.send) until you're done with the form.

process.stdout.write(createReqFormat(req));

res.on('finish', function(){
  process.stdout.write(createResFormat(res));
});

if(req.method !== 'GET') {
  var form = new formidable.IncomingForm();
  form.parse(req, function(err, fields, files){
    if (err) return next(err);
    process.stdout.write('\n Parameters:' + util.inspect(fields));
    next();
  });
} else {
  next();
}
