Configuration Options

Each configuration accepts an options object:

interface Options {
  ignores?: string[]; // Files to ignore
  plugins?: Record<string, TSESLint.Linter.Plugin>; // Additional ESLint plugins
  rules?: Record<string, TSESLint.SharedConfig.RuleEntry>; // Custom rule configurations
}

For detailed information:

ignores: See ESLint ignore patterns documentation
plugins: See ESLint plugins configuration
rules: See ESLint rules configuration

The Typescript plugin accept setting some languageOptions:

interface Options {
  ignores?: string[];
  plugins?: Record<string, TSESLint.Linter.Plugin>;
  rules?: Record<string, TSESLint.SharedConfig.RuleEntry>;
  languageOptions?: Linter.LanguageOptions; // typescript() only
}

The betterTailwindCss plugin accept settings:

interface Options {
  ignores?: string[];
  plugins?: Record<string, TSESLint.Linter.Plugin>;
  rules?: Record<string, TSESLint.SharedConfig.RuleEntry>;
  settings?: {
    'better-tailwindcss'?: {
      entryPoint?: string;
      tailwindConfig?: string;
      attributes?: any[];
      callees?: any[];
      variables?: any[];
      tags?: any[];
    };
  };
}

Example usage with options:

export default combine(
  {
    languageOptions: {
      globals: {
        ...globals.browser,
        __APP_VERSION__: 'readonly',
        MaybeHTMLElement: 'readonly',
      },
    },
  },
  typescript({
    ignores: ['*.test.ts'],
    rules: {
      '@typescript-eslint/no-explicit-any': 'off',
    },
  }),
  stylistic({
    rules: {
      '@stylistic/indent': ['error', 4],
    },
  }),
  betterTailwindCss({
    settings: {
      'better-tailwindcss': {
        entryPoint: 'src/styles/global.css',
      }
    },
  })
);
