Installation

npm install slop --save

/**
 * Module dependencies.
 */
var slop = require('slop');
/**
 * Process.argv will be an array.
 * Array:
 *  1st element will be 'node'
 *  2nd element will be '/path/to/this/JavaScript/file'
 *  3rd - Nth elements will be additional command line arguments
 *
 * Introspect Node arguments vector for:
 * - optional port to begin accepting connections
 *
 * Options.get() values may yield:
 * - {undefined}
 * - {boolean} true
 * - {string} (non-empty)
 *
 * Options.has() values may yield:
 * - {boolean} true
 * - {boolean} false
 */
var options = slop().parse(process.argv),
    port = options.get('port'),
    debug = options.has('debug');
/**
 * Default the Port value if it's not defined.
 */
port = (typeof port === 'string' && Number(port) >= 0) ? port : '8080';

if (debug) {
    console.log('------------------------------');
    console.log('Incoming Option Values.');
    console.log('Port: ' + port);
    console.log('------------------------------');
}
