requires-port

The module name says it all, check if a protocol requires a given port.

Installation

This module is intended to be used with browserify or Node.js and is distributed in the public npm registry. To install it simply run the following command from your CLI:

npm install --save requires-port

Usage

The module exports it self as function and requires 2 arguments:

• The port number, can be a string or number.
• 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.

'use strict';

var required = require('requires-port');

console.log(required('8080', 'http')) // true
console.log(required('80', 'http'))   // false

is-port-reachable

While `requires-port` helps determine if a port is required for a protocol, `is-port-reachable` checks if a port is reachable on a host. It's more about network accessibility rather than protocol requirements, making it useful for testing if services are up and accessible.

get-port

The `get-port` package is designed to find an available port on the system. Unlike `requires-port`, which is about understanding protocol defaults, `get-port` is useful for dynamically selecting an open port to avoid conflicts, especially during development or when launching new server instances.
