Fingerprint public folder assets with build ID

[mohsen1]

Feature request

Apologizes if it is a repeat issue. I did a fair amount of searching but no issue was exactly asking for this.

We have a bunch of files in the public folder. These files are:

• favicon
• app manifest JSON
• open search XML files
• etc

Currently we have a script for uploading contents of. .next folder to S3 and use assetPrefix to deliver the built files via our CDN. The CDN delivery is omitted from the public folder contents. I can upload contents of pubic folder to S3 and deliver via CDN in production by having lines like this is my _document:

         <link
            rel="icon"
            href={`${process.env.NODE_ENV === 'production' ? assetPrefix : ''}/favicon.ico`}
            type="image/x-icon"
          />

This doesn't seem right. I wish Next would take public folder and fingerprinted those assets. Because with above solution, a new favicon will show up in prod the moment S3 upload is done.

Possible solution

I'm expecting Next.js rewrite href and URLs referring to assets in the public directory and build them into the distDir folder.
