How to set httpOnly cookies?

[kamilml]

I want to make a login in my web app, using an endpoint in another server (other domain).

I can't save httpOnly cookies in the domain of my app, then I need to make something like a reverse proxy in the same server of the webapp.

Before, I did it with express, can I do it with API routes or something without express? Or maybe using serverless functions of vercel?

Generally the reverse proxy is done at infrastructure layer (e.g. nginx) to make the requests faster (Node is not that good at this). For development you can use the experimental rewrites feature:

module.exports = {
  experimental: {
    rewrites() {
      return [
        {
          source: '/api/:path*',
          destination: API_PATH
        }
      ];
    }
  }
};
