Make the plugin work with the new eslint.config.js config format

[acommodari]

I want to request a feature.

I would like for this plugin to work with the new flat config eslint.config.js file format that will become the default in eslint@9 and that I'm trying to currently use in [email protected]`

I want to report a bug.

Not sure if this is considered a bug since eslint mentioned that all plugins should work out of the box. Maybe this plugin is doing something non-standard?

Reproducer

// eslint.config.js
const js = require('@eslint/js');
const sonarjs = require('eslint-plugin-sonarjs');
const globals = require('globals');

module.exports = [
	{
		ignores: ['**/tests/coverage', '**/.serverless', '**/.esbuild'],
	},
	js.configs.recommended,
	sonarjs.configs.recommended,
	{
		files: ['./services/**/*.js', './packages/**/*.js', './libs/**/*.js', './jest.config.js', 'eslint.config.js'],
		languageOptions: {
			globals: {
				...globals.node,
			},
			ecmaVersion: 2022,
		},
		linterOptions: {
			noInlineConfig: true,
			reportUnusedDisableDirectives: true,
		},
		plugins: {
			sonarjs,
		},
		rules: {},
	},
];

Expected behavior

It should lint correctly however I get the following error message:

Oops! Something went wrong! :(

ESLint: 8.41.0

TypeError: Key "plugins": Key "0": Expected an object.

Thanks for reporting, we will have a look at this. I also created a related issue in our Sonar plugin repo https://github.com/SonarSource/SonarJS/issues/3968

Hi, could you add a warning on your readme somewhere about this? It would save people from trying to debug their eslint.
