Configuration Templates

Modern Flat Config (ESLint 9.x)

// eslint.config.js
import js from '@eslint/js';
import typescript from '@typescript-eslint/eslint-plugin';
import typescriptParser from '@typescript-eslint/parser';

export default [
  js.configs.recommended,
  {
    files: ['**/*.{ts,tsx}'],
    languageOptions: {
      parser: typescriptParser,
      parserOptions: {
        ecmaVersion: 'latest',
        sourceType: 'module',
        project: './tsconfig.json',
      },
    },
    plugins: {
      '@typescript-eslint': typescript,
    },
    rules: {
      '@typescript-eslint/no-unused-vars': 'error',
      '@typescript-eslint/no-explicit-any': 'warn',
    },
  },
];

Legacy Config

// .eslintrc.js
module.exports = {
  root: true,
  env: { node: true, es2022: true },
  parser: '@typescript-eslint/parser',
  plugins: ['@typescript-eslint'],
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/recommended',
  ],
};
