"ReferenceError: handler is not defined" in Node.js

This is the first line of my Node.js app:

var app     = require('http').createServer(handler);

When I try to start it doing node index.js the result is:

/home/username/public_html/index.js:1
var app     = require('http').createServer(handler);
                                           ^
ReferenceError: handler is not defined

My Node.js version is 0.12.4

You say that's the first line of your code. The problem is that you do not define the handler variable. It should be a function that responds to a request event. Since it is optional, you can (if you wish) leave it out entirely and add handlers for events later on.

var app     = require('http').createServer();
