Import API endpoint into getServerSideProps

[rawcomposition]

So when using getServerSideProps in Next.js, the docs recommend not directly using fetch(), but instead, importing the API endpoint function directly. I tried doing this, but got hung up when trying to incorporate my MongoDB middleware. I end up with something like this:

const handler = nextConnect();
handler.use(middleware);

handler.get(async (req, res) => {
    const post = await req.db.collection("posts").findOne();
    res.send({
        post: post,
    });
});

export default handler;

How could I refactor this in such a way that I could directly import this endpoint into my getServerSideProps function? Or should I ignore the documentation suggestions and just use fetch()?

I was thinking I could do something like like below, but I'm not sure how to allow my getPost function to access the middleware DB connection.

export const getPost = async () => {
    const post = await req.db.collection("posts").findOne();
    return post;
}

handler.get(async (req, res) => {
    res.send({
        post: getPost(),
    });
});

and then in my next.js page:

import { getPost } from './api/post';
...
export async function getServerSideProps(context) {
    return {
        props: {
            post: getPost(),
        }
    }
}
