Now we'll add the port logic as shown in the following code:

var port; app.configure('production', function(){ port = 80; app.use(express.errorHandler({dumpExceptions: true})); }); // Routes app.get('/', routes.index); app.listen(port || 3000);

So our port is set based upon the environment, if port is empty we default to 3000.

We could initialize our production server with:

sudo NODE_ENV=production node app.js

Or for Windows:

set NODE_ENV=production node app.js

When attempting to run the server with NODE_ENV set to production, if we receive TypeError: Cannot read property 'port' of null, it's likely that a service is already running on port 80. We would need to stop this service in order to test our code. For instance, if Apache is running on our system, it's probably hosting through port 80. We can stop Apache with sudo apachectl -k stop (or net stop apache2.2 on Windows).
