Migrate to Eslint v9

[conarti]

Hi! If you’d like to test the new version of the plugin with me, you’re welcome to join. Feel free to report any issues in this PR.

Usage:

1. Install the new package:
   npm i -D @conarti/eslint-plugin-feature-sliced@next
2. Set up in eslint.config.js:

import featureSliced from '@conarti/eslint-plugin-feature-sliced';

export default [
  featureSliced(), // By default, uses the "recommended" config from v1. Please refer to the "README" for detailed setup.
];

Planned tasks before publishing the stable version:

• Add support for eslint v9
• Add factory function for simpler usage
• Add @x support
• Add documentation for the new setup
• Add documentation for the old setup
• Add notes about steiger in docs
• Use better build flow (use any builder)
• Use better eslint config
• Set up a better publishing flow, remove unnecessary 'scripts', try to use github releases and github ci for tests, publish and releases
• Specify correct eslint versions in peerDependencies and check other fields in package.json
• Ensure that the new version cannot be installed on projects using eslint <=8
• Fix usage with the tseslint.config(...) factory
• Test the package in as many projects as possible and fix newly discovered issues

Hello! How to solve this issue?

ESLint: 9.30.1 - TypeError: featureSliced is not a function

esling.config.js:

const js = require('@eslint/js');
const { FlatCompat } = require('@eslint/eslintrc');
const { defineConfig } = require('eslint/config');
const featureSliced = require('@conarti/eslint-plugin-feature-sliced');

const compat = new FlatCompat({
  recommendedConfig: js.configs.recommended,
  allConfig: js.configs.all,
});

module.exports = defineConfig([
  featureSliced(),
  {
    ignores: ['config/**/*', '**/*.stories.tsx', 'openapi-typescript/**/*'],
  },
  ...
