HTTP status utility for node.
|
|
|
|
## API
|
|
|
|
```js
|
|
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.
|
|
|
|
```js
|
|
status(403) // => 403
|
|
status('403') // => 403
|
|
status('forbidden') // => 403
|
|
status('Forbidden') // => 403
|
|
status(306) // throws, as it's not supported by node.js
|
|
```
|
|
|
|
### 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.
|
|
|
|
```js
|
|
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.
|
|
|
|
```js
|
|
status['not found'] // => 404
|
|
status['Not Found'] // => 404
|
|
```
|
|
|
|
### status.redirect[code]
|
|
|
|
Returns `true` if a status code is a valid redirect status.
|
|
|
|
```js
|
|
status.redirect[200] // => undefined
|
|
status.redirect[301] // => true
|
|
```
|
|
|
|
### status.empty[code]
|
|
|
|
Returns `true` if a status code expects an empty body.
|
|
|
|
```js
|
|
status.empty[200] // => undefined
|
|
status.empty[204] // => true
|
|
status.empty[304] // => true
|
|
```
|
|
|
|
### status.retry[code]
|
|
|
|
Returns `true` if you should retry the rest.
|
|
|
|
```js
|
|
status.retry[501] // => undefined
|
|
status.retry[503] // => true
|
|
```
|
|
|
|
## Adding Status Codes
|
|
|
|
The status codes are primarily sourced from http://www.iana.org/assignments/http-status-codes/http-status-codes-1.csv.
|
|
Additionally, custom codes are added from http://en.wikipedia.org/wiki/List_of_HTTP_status_codes.
|
|
These are added manually in the `lib/*.json` files.
|
|
If you would like to add a status code, add it to the appropriate JSON file.
|
|
|
|
To rebuild `codes.json`, run the following:
|
|
|
|
```bash
|
|
# update src/iana.json
|
|
npm run fetch
|
|
# build codes.json
|
|
npm run build
|
|
```
