Node.js Module To Check If A Port Is In Use

Install into your project or use your package.json:

npm install portcheck

And then:

var portcheck = require('portcheck');

To check if a port is in use:

var PortEightyIsInUse = portcheck.IsInUse(80)

It will return false if not in use, or a text error if it is.
