Res Cookie

Set cookie name to value, which may be a string or object converted to JSON. The path option defaults to "/".

res.cookie('name', 'tobi', { domain: '.example.com', path: '/admin', secure: true })
res.cookie('rememberme', '1', { expires: new Date(Date.now() + 900000), httpOnly: true })

The maxAge option is a convenience option for setting "expires" relative to the current time in milliseconds. The following is equivalent to the previous example.

res.cookie('rememberme', '1', { maxAge: 900000, httpOnly: true })

An object may be passed which is then serialized as JSON, which is automatically parsed by the bodyParser() middleware.

res.cookie('cart', { items: [1, 2, 3] })
res.cookie('cart', { items: [1, 2, 3] }, { maxAge: 900000 })

Signed cookies are also supported through this method. Simply pass the signed option. When given res.cookie() will use the secret passed to express.cookieParser(secret) to sign the value.

res.cookie('name', 'tobi', { signed: true })

Later you may access this value through the <a href="#req.signedCookies">req.signedCookie</a> object.
