|
|
<!-- eslint-disable no-unused-vars -->
|
|

var status = require('statuses')
|
|
```
|
|
|
|
### status(code)
|
|
|
|
Returns the status message string for a known HTTP status code. The code
|
|
may be a number or a string. An error is thrown for an unknown status code.
|
|
|
|
<!-- eslint-disable no-undef -->
|
|
|
|
```js
|
|
status(403) // => 'Forbidden'
|
|
status('403') // => 'Forbidden'
|
|
status(306) // throws
|
|
```
|
|
|
|
### status(msg)
|
|
|
|
Returns the numeric status code for a known HTTP status message. The message
|
|
is case-insensitive. An error is thrown for an unknown status message.
|
|
|
|
<!-- eslint-disable no-undef -->
|
|
|
|
```js
|
|
status('forbidden') // => 403
|
|
status('Forbidden') // => 403
|
|
status('foo') // throws
|
|
```
|
|
|
|
### status.codes
|
|
|
|
Returns an array of all the status codes as `Integer`s.
|
|
|
|
### status.code[msg]
|
|
|
|
Returns the numeric status code for a known status message (in lower-case),
|
|
otherwise `undefined`.
|
|
|
|
<!-- eslint-disable no-undef, no-unused-expressions -->

|
```js

status['not found'] // => 404
|
|

|
|
|
|

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

|
|
```
|
|
|
|
### status.message[code]
|
|
