uploading images in public dir reactjs/nextjs

I've been trying to upload images in the /public directory this code is working fine locally (Windows OS)

import getConfig from "next/config";
import fs from "fs";
const address=path.join(getConfig().serverRuntimeConfig.PROJECT_ROOT, `/public/uploads/users/${username}`);
if (!fs.existsSync(address)) {
  fs.mkdirSync(address, { recursive: true });
}

I'm using multer for file uploading from client-side.

The above code is working fine on window os locally but in after deployment at vercel it throws the error:

Vercel as a platform does not allow persistent file storage as these are serverless functions, they encourage uploads to a bucket like s3 -

https://vercel.com/docs/concepts/solutions/file-storage

  • Create a Serverless Function to return a presigned URL.
  • From the front-end, call your Serverless Function to get the presigned POST URL.
  • Allow the user to upload a file on the front-end. Forward the
  • file to the POST URL.

Note: here the presigned url is a s3 location that you are creating as a location.

They also post multiple examples by using different examples using s3 or Google storage bucket.
