ESLint version

v9.26.0

What problem do you want to solve?

eslint-config-prettier is commonjs only + exports.rules/exports.name, so import * as eslintConfigPrettier from 'eslint-config-prettier' should be used when using eslint.config.mjs, but node will add an extra default property on eslintConfigPrettier in this case.

import * as eslintConfigPrettier from 'eslint-config-prettier'

console.log(Object.keys(eslintConfigPrettier)) // [ 'default', 'rules' ]

import * as eslintConfigPrettierFlat from 'eslint-config-prettier/flat'

console.log(Object.keys(eslintConfigPrettierFlat)) // [ 'default', 'name', 'rules' ]

But those can not be used directly as ESLint flat config due to the default property:

Oops! Something went wrong! :(

ESLint: 9.26.0

ConfigError: Config (unnamed): Unexpected key "default" found.

What do you think is the correct solution?

1. Ignore default key
2. Ignore all unknown keys, I don't get why we're vailidating the unknown keys actually, for example, we had to add an extra /flat entry only for adding a new name property for flat config which is unavailable in eslintrc, this is a bit ridiculous to myself: fix: separate the /flat entry for compatibility prettier/eslint-config-prettier#309
