Use the Response.cookie() method to manipulate your cookies.

Examples:

res.cookie('username', 'Flavio')

This method accepts a third parameter which contains various options:

res.cookie('username', 'Flavio', { domain: '.flaviocopes.com', path: '/administrator', secure: true })

res.cookie('username', 'Flavio', { expires: new Date(Date.now() + 900000), httpOnly: true })

maxAge	set the expiry time relative to the current time, expressed in milliseconds
path	the cookie path. Defaults to /
secure	Marks the cookie HTTPS only
