Why not use Node.js Packages in MiddleWare？

[CheaterScript]

Hi，I want import casbin in MiddleWare，but get error:

Module not found: Can't resolve 'fs'

How to fix it?

Hello.

Middlewares are run by the Next.js Edge Runtime which is based on standard Web APIs.

As stated by the documentation:
https://nextjs.org/docs/api-reference/edge-runtime#unsupported-apis

Native Node.js APIs are not supported. For example, you can't read or write to the filesystem

Thank you! I get it.

is this by design that middleware should only have edge friendly function? or can we configure a next app/middlewares to support the Native Node.js APIs for Node environment.
