ESLint 9+ Flat Config (Recommended)

Create an eslint.config.js file (or eslint.config.mjs) in your project root:

const mastermindzhConfig = require('@mastermindzh/eslint-config');

module.exports = [
  ...mastermindzhConfig,
  {
    // Your custom rules here
    rules: {
      // Example: override a rule
      'no-console': 'warn',
    },
  },
];

TypeScript Projects

For TypeScript projects, you may also want to add TypeScript-specific configuration:

const mastermindzhConfig = require('@mastermindzh/eslint-config');
const tseslint = require('typescript-eslint');

module.exports = [
  ...mastermindzhConfig,
  ...tseslint.configs.recommended,
  {
    files: ['**/*.ts', '**/*.tsx'],
    rules: {
      // TypeScript-specific rules
    },
  },
];

migration-from-legacy-eslintrc

If you're migrating from an older version (2.x) that used .eslintrc format:

1. Remove your .eslintrc.* files
2. Remove your .eslintignore file
3. Create an eslint.config.js file with the flat config format shown above
4. Add ignores directly in the config:

const mastermindzhConfig = require('@mastermindzh/eslint-config');

module.exports = [
  // Global ignores
  {
    ignores: ['dist/**', 'build/**', 'node_modules/**'],
  },
  ...mastermindzhConfig,
  {
    // Your custom rules
  },
];
