Can't set a cookie using NextJS 9's API Route

Typically it seems that when using Express, in the res object there is cookie so you can do something like:

res.cookie('session', sessionCookie, options);

In the API routes offered by NextJS in Next 9, when looking at res, this does not exist. Is there a way to set the cookie for a response object in a Next API Route function?

Adapted from offical repo middleware example, you can set Set-Cookie header via res like so:

import { serialize } from 'cookie';



function (req, res) {

   // ...

   // setHeader(headerName: string, cookies: string | string[])

   // can use array for multiple cookies

   res.setHeader('Set-Cookie', serialize('token', 'token_cookie_value', { path: '/' }));

}
