cookie 

cookie is a basic cookie parser and serializer. It doesn't make assumptions about how you are going to deal with your cookies. It basically just provides a way to read and write the HTTP cookie headers.

See RFC6265 for details about the http header for cookies.

how?

npm install cookie

javascript
var cookie = require('cookie');

var hdr = cookie.serialize('foo', 'bar');
// hdr = 'foo=bar';

var cookies = cookie.parse('foo=bar; cat=meow; dog=ruff');
// cookies = { foo: 'bar', cat: 'meow', dog: 'ruff' };
