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](https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml)
|
|
* The [Node.js project](https://nodejs.org/)
|
|
* The [NGINX project](https://www.nginx.com/)
|
|
* The [Apache HTTP Server project](https://httpd.apache.org/)
|
|

|
|
[npm registry](https://www.npmjs.com/). Installation is done using the
|
|
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|

|
|
```sh
|
|
$ npm install statuses
|

|
|
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
|
|
|
|

|
|

|
|
|
|
### status.codes
|

|
Returns an array of all the status codes as `Integer`s.
|
|
|
|
### var msg = status[code]
|

|
|
|
|

```js
|
|
status[404] // => 'Not Found'
|
|
```
|
|
|
|
### var code = status[msg]
|
|
|
|

|
|
lower-cased. `undefined` for invalid `status message`s.
|
|
|
|
<!-- eslint-disable no-undef, no-unused-expressions -->
|
|
|
|
```js
|
|
status['not found'] // => 404
|
|
status['Not Found'] // => 404
|
|
```
|
|
|
|
### status.redirect[code]
|
|
|
|
Returns `true` if a status code is a valid redirect status.
|
|
|
|
<!-- eslint-disable no-undef, no-unused-expressions -->
|
|
|
|
```js
|
|
status.redirect[200] // => undefined

|
|

|
|
|
|
### status.empty[code]
