To install it simply run the following command from your CLI: ```j npm install --save requires-port ``` ## Usage The module exports it self as function and requires 2 arguments: 1. The port number, can be a string or number. 2. Protocol, can be `http`, `http:` or even `https://yomoma.com`. We just split it at `:` and use the first result. We currently accept the following protocols: - `http` - `https` - `ws` - `wss` - `ftp` - `gopher` - `file` It returns a boolean that indicates if protocol requires this port to be added to your URL. ```js 'use strict'; var required = require('requires-port'); console.log(required('8080', 'http')) // true console.log(required('80', 'http')) // false ``` # License MIT
