You can change this globally by setting: ```js portfinder.basePort = 3000; // default: 8000 portfinder.highestPort = 3333; // default: 65535 ``` or by passing optional options object on each invocation: ```js portfinder.getPort({ port: 3000, // minimum port stopPort: 3333 // maximum port }, callback); ``` ## Run Tests ``` bash $ npm test ``` #### Author: [Charlie Robbins][0] #### Maintainer: [Erik Trom][1] #### License: MIT/X11 [0]: http://nodejitsu.com [1]: https://github.com/eriktrom
