Statuses

• The IANA Status Code Registry
• The Node.js project
• The NGINX project
• The Apache HTTP Server project

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install statuses

API

var status = require('statuses')

var code = status(Integer || String)

If Integer or String is a valid HTTP code or status message, then the appropriate code will be returned. Otherwise, an error will be thrown.

status(403) // => 403
status('403') // => 403
status('forbidden') // => 403
status('Forbidden') // => 403
status(306) // throws, as it's not supported by node.js
