AustinDizzy is correct.
var utils = require('util');Note that "utils" != "util". "utils" will throw an error. Please update accordingly.
According to this article the following code (for example in your post3) do not have to work always:
req.on('end', ...
It is possible that it has to be changed to:
req.addListener('end', ...
in some cases
I read your blog on the node.js POST data. Recently I came across a problem where I even though using the body-parser middleware, I am unable to read the POST data sent to my webhook (built on node.js). I would appreciate if you can take a look at it and let me know what I am doing wrong. I opened an issue on the body-parser module git : https://github.com/expressjs/body-parser/issues/213
