usage in eslint flat config

how to use it in the new eslint flat config

[electrovir]

It appears to not even be importable because it is built in CommonJS. I get No "exports" main defined errors when trying to import anything from this package into an ESLint v9 flat config.

Specifically, do this:

import {fileURLToPath} from 'node:url';
import {FlatCompat} from '@eslint/eslintrc';

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

const compat = new FlatCompat({
    baseDirectory: __dirname,
});

// ESM config export
export default [
    ...compat.plugins('require-extensions'),
    ...compat.extends('plugin:require-extensions/recommended'),
    // rest of your config
]

The new @eslint/compat tool that's supposed to help migrate your .eslintrc incorrectly migrates this plugin, because it can't be imported.

You can still use compat.plugins, but you'll need to remove the import and fixupPluginRules call that is generated.
