Statuses

HTTP status utility for node.

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

- 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

## 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 `Integer`s.

## var msg = status[code]

Map of `code` to `status message`. `undefined` for invalid `code`s.

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 message`s.

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
status.empty[304] // => true

## status.retry[code]

Returns `true` if you should retry the rest.

status.retry[501] // => undefined
status.retry[503] // => true
