You can make JSON-string manually:

res.cookie('cart', JSON.stringify({ items: [1,2,3] }) );

Prefix j: added in ./express/lib/response.js (lines 787-789):

var val = typeof value === 'object'
    ? 'j:' + JSON.stringify(value)
    : String(value);

where value is your object { items: [1,2,3] }

It's not part of any standard, as the RFC for cookies says the value can only be a string. Ideally if we followed the standard, we would reject your cookie if it wasn't a string. As a convenience, Express.js allows you to set non-strings as the values, and we'll JSON.stringify the value, pre-pending a j: so we know the value should be JSON.parsed when we read it again for you.
