[codemod][FP] nuxt/4/migration-recipe

[xmatthias]

Original

import withNuxt from './.nuxt/eslint.config.mjs';

Expected

import withNuxt from './.nuxt/eslint.config.mjs';

Actual

import withNuxt from '.nuxt/eslint.config.mjs';

(nothing else in the eslint file was modified).

Estimated impact

Numbers about your specific codemod run:

• Total number of files/instances transformed: 1
• Number of files/instances missed by the codemod (FN): 0
• Number of files/instances mistakenly transformed (FP): 1

Logs:

// Please insert the contents of a log file generated by the codemod run here.

Additional context

In a regular nuxt project with eslint using flatconfig configured, i'm running the following migration script (according to the nuxt docs).

npx codemod@latest nuxt/4/migration-recipe

This also updates eslint.config.mjs (wrongly)

Result:

Now unfortunately - the modification causes eslint to complain (quite loudly)

Oops! Something went wrong! :(c to cancel.

ESLint: 9.9.0

Reverting this line fixes the problem - though i guess this shouldn't happen for a smooth migration between nuxt3 to nuxt4.

Adding a bit more details here - it seems to happen in nuxt/4/file-structure - only leaving that part ticked yields the following output - somewhere in the middle.
