Globally access nextjs req

[mwisner]

Hi!

I'm wondering if anyone has any decent solutions for accessing the req object from anywhere while running in Node. Similar to how we can use withRouter HOC and useRouter anywhere in React land... I'd like to be able to do something similar with the req object.

I found this: #7393. But the accepted solution appears to be one using a custom server. Does anyone have any ideas for how to accomplish this without a custom server?

More specifically, on the client, I can do this: window.location.host to get the host. I need to be able to do something similar on the server. Ideally, if I could write some sort of function like:

/**
 *  
*/
const getHost = () => {
   //
   // Client side host
    if (typeof window !== 'undefined') {
      return window.location.host;
    } 

   //
   // Server side host
   // ??? How to get the server host? 
}

If you want to get the request object while on the server, you would have to do it something like this on each page:

export async function getServerSideProps(context) {
  const { req } = context
  return {
    props: {}, 
  }
}

You could alternatively use a custom _app.js and get the req in getInitialProps and then pass that to your components. Although I would say the above solution is better so you could do it on a per-page basis.
