Leveraging the NextAuth hooks, employ the useSession() function within the getServerSideProps

Question

Leveraging the NextAuth hooks, employ the useSession() function within the getServerSideProps

I'm currently working on retrieving data from my server based on the user who is logged in. I am utilizing Next-Auth and usually, I can easily obtain the session by calling:

const { data: session } = useSession();

In a functional component, this works fine but when I try to do the same in getServerSideProps(), it doesn't work.

To fetch the data, I need to send a GET request like this:

export async function getServerSideProps() {
  const res = await fetch(
    `http://localhost:5000/api/users/${session.id}/following`
  );
  const isFollowing = res.json();
  return {
    props: { props: isFollowing },
  };
}

where the current user's session ID needs to be dynamically inserted.

Can anyone guide me on how I can access my session ID inside getServerSideProps?

When using the react-hook useSession, it is important to remember that it can only be used within a Component. For server-side applications, there is an alternative method provided by the Next-Auth package called getSession. https://next-auth.js.org/v3/getting-started/client#getsession

Example of Server-Side Implementation:

    import { getSession } from "next-auth/client"

    export default async (req, res) => {
      const session = await getSession({ req })
      /* ... */  
     res.end()
    }

Please note that when using getSession() on the server side, you must include {req} or a context object as a parameter.

If you want to include headers in an inner fetch request within the getServerSideProps function, you need to re-assign them from the initial request. This is because the inner fetch does not automatically inherit cookies, tokens, or any other headers.

export async function getServerSideProps(ctx) {
  const headers = ctx.req.headers; // Contains cookies, jwt, etc.
  const res = await fetch(
    `http://localhost:5000/api/users/${session.id}/following`,
    {headers}
  );
  const isFollowing = await res.json();
  return {
    props: { isFollowing },
  };
}

As of the v4 release of NextAuth, the method previously known as getSession has been updated to getServerSession. For more details, you can refer to the official documentation at https://next-auth.js.org/configuration/nextjs#getserversession. Below is a snippet demonstrating how this method can be imported and used:

// Import your NextAuth options (e.g., from '../app/api/auth/[...nextauth]/route')
import { authOptions } from '../app/api/auth/[...nextauth]/route'
import { getServerSession } from "next-auth"

// This function is executed on every request
export async function getServerSideProps(context) {
    const session = await getServerSession(context.req, context.res, authOptions)
    // Example usage: fetch data using the session ID
    const mydata = await fetch(`http://localhost/example/${session.id}`);
   
    // Pass retrieved data to the page via props
    return { props: { mydata } }
}
