## Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.
|
|
|
|
This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var headers = {}
|
|
, c = caseless(headers)
|
|
;
|
|
c.set('a-Header', 'asdf')
|
|
c.get('a-header') === 'asdf'
|
|
```
|
|
|
|
## has(key)
|
|
|
|
Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.
|
|
|
|
```javascript
|
|
c.has('a-header') === 'a-Header'
|
|
```
|
|
|
|
## set(key, value[, clobber=true])
|
|
|
|
Set is fairly straight forward except that if the header exists and clobber is disabled it will add `','+value` to the existing header.
|
|
|
|
```javascript
|
|
c.set('a-Header', 'fdas')
|
|
c.set('a-HEADER', 'more', false)
|
|
c.get('a-header') === 'fdsa,more'
|
|
```
|
|
|
|
## swap(key)
|
|
|
|
Swaps the casing of a header with the new one that is passed in.
|
|
|
|
```javascript
|
|
var headers = {}
|
|
, c = caseless(headers)
|
|
;
|
|
c.set('a-Header', 'fdas')
|
|
c.swap('a-HEADER')
|
|
c.has('a-header') === 'a-HEADER'
|
|
headers === {'a-HEADER': 'fdas'}
|
|
```
