What?

If there is a middleware.js or middleware.ts file in Next.JS 14, running next build shows the following warning:

./node_modules/next/dist/esm/shared/lib/router/utils/app-paths.js
A Node.js module is loaded ('url' at line 3) which is not supported in the Edge Runtime.
Learn More: https://nextjs.org/docs/messages/node-module-in-edge-runtime

Import trace for requested module:
./node_modules/next/dist/esm/shared/lib/router/utils/app-paths.js

This PR will remove the warning.
