Support ESLint Flat config

[sdavids]

• eslint-plugin-jest-dom version: 5.5.0
• node version: 22.13.0
• npm version: 10.9.2

eslint.config.js

import jestDom from 'eslint-plugin-jest-dom';

export default [
  {
    files: ['**/*.test.js'],
    ...jestDom.configs['flat/recommended'],
  },
];

Flat config has been the default for 10 months now.

ESLint 8 has reached EOL

While you are at it, you might want to update README.md with flat config examples as well.

@sdavids can you provide more details to what you're actually running into? We already support ESLint v9 + flat config (with examples of that in our README), and I personally have been using it in cjs and mjs configs without any issues

PEBCAK

files: ['src/**/*.test.js'] does not match src/a.test.js

Should have used npx eslint --inspect-config 😕
