Readme

find-port
find an unused port in your localhost
var findPort = require('find-port')

// scan a range
findPort('127.0.0.1', 8000, 8003, function(ports) {
	console.log(ports)
})

// scan explicitly
findPort('127.0.0.1', [8000, 8011], function(ports) {
	console.log(ports)
})

  • Since version 2.0.0 a local interface must be specified
  • This module is not designed to scan remote ports only local ones.
