Custom Configuration

Adding Custom Rules

module.exports = defineConfig({
  packageRoot: __dirname,
  preset: 'web',
  rules: {
    'no-console': 'warn',
    '@typescript-eslint/no-unused-vars': 'error',
  },
});

Adding Overrides

module.exports = defineConfig({

      rules: {
        'max-lines': 'off',
      },
    },
  ],
});
