Statuses

HTTP status utility for node.

This module provides a list of status codes and messages sourced from a few different projects:

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

status.STATUS_CODES

Returns an object which maps status codes to status messages, in the same format as the Node.js http module.

status.codes

Returns an array of all the status codes as Integers.

var msg = status[code]

Map of code to status message. undefined for invalid codes.

status[404] // => 'Not Found'

var code = status[msg]

Map of status message to code. msg can either be title-cased or lower-cased. undefined for invalid status messages.

status['not found'] // => 404
status['Not Found'] // => 404

status.redirect[code]

Returns true if a status code is a valid redirect status.

status.redirect[200] // => undefined
status.redirect[301] // => true

status.empty[code]

Returns true if a status code expects an empty body.

status.empty[200] // => undefined
status.empty[204] // => true
