Failed to patch ESLint because the calling module was not recognized.

The following results in an error:

pnpm dlx @oxlint/migrate eslint.config.mjs --type-aware

This could be related. Although this setup is the default for Nextjs projects these days.

microsoft/rushstack#5049

You have eslint-config-next installed, which uses this rushstack dependency.
My guess it does some magic on the fly. See another issue from them:
microsoft/rushstack#4965 (comment)

Closing because this plugin can not do anything for it.

[alexaka1]

Thanks for the reply! So the conclusion is NextJS projects cannot migrate to Oxlint yet?

[Sysix]

Only if you are using the eslint-config-next package. eslint-plugin-next is usable.
EDIT:

NextJS projects cannot migrate to Oxlint yet?

They just can not use this script

[alexaka1]

I did some more reading, and afaik eslint-config-next is and will be the default setup for Next 15 and 16. It does a bit more than just a wrapper around other eslint configs: https://github.com/vercel/next.js/blob/canary/packages/eslint-config-next/index.js

So it would be nice to at least mention this in an FAQ somewhere, that hey, create-next-app will not be compatible with this migration, you have to manually setup Eslint instead.

These are the current defaults as of today:

After talking with @TheAlexLichter, I will look into a user-friendly solution
