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.


javascript var headers = {} , c = caseless(headers) ; c.set('a-Header', 'asdf') c.get('a-header') === 'asdf'


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'


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'}
