Headers

This is a commonjs compatible Javascript module for parsing and format the following HTTP headers:

• Content-Type (per RFC 2616)
• Accept (per RFC 2616)
• Accept-Language (per RFC 2616)
• Accept-Charset (per RFC 2616)
• Accept-Encoding (per RFC 2616)
• Cookie (per http://tools.ietf.org/html/draft-ietf-httpstate-cookie-18)
• Set-Cookie (per http://tools.ietf.org/html/draft-ietf-httpstate-cookie-18)
• Cache-Control (per RFC 2616)
• Link (per RFC 5988)

Parsing and formatting is implemented by a header module which has two functions parse, and format. Each of these methods accept two arguments - the name of the header, and either a string (for parsing) or an object (for formatting. The structure of the object is specific to each header, but is easily guessable. See the tests directory for examples.

Example

Here is an example to parse a Link header.

var header = require('header');
var str = "<http://foo.com>;rel='http://some.rel.com alternate';title='hello';type='application/xml'";
l = header.parse('Link', val);
console.log(sys.inspect(l));

Formatting follows the same style.

var header = require('header');
sys.log(header.format('Link', {
  href : 'http://www.example.org',
  rel : ['related'],
  title : 'Hello World',
  type : 'text/html'
}));

Installing

npm install headers
