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.
