Packages

All packages live under the @ladamczyk/* namespace and are versioned together.

qoq-cli

The command-line entry point. Handles formatting, linting, and testing of your JS/TS code by orchestrating every other package through the --check, staged, and --fix commands. Includes the Config Wizard, config handlers, and the executors that run each underlying tool. Monorepo-aware via package.json workspaces.

qoq-eslint-v9-*

Opinionated Flat Config presets that bundle every plugin and setting needed for a given stack. Each exports both CommonJS and ESM and can be used as-is or as a base for your own rules.

Every preset ships with a prebuilt ESLint Config Inspector so you can browse exactly which rules, plugins, and settings it enables — before you install it. Pick the variant that matches your language and test setup to open its dedicated page under ESLint Presets:

Package	Stack
@ladamczyk/qoq-eslint-v9-js	JavaScript
@ladamczyk/qoq-eslint-v9-js-react	JavaScript + React
@ladamczyk/qoq-eslint-v9-js-jest	JavaScript + Jest
@ladamczyk/qoq-eslint-v9-js-jest-rtl	JavaScript + Jest + React Testing Library
@ladamczyk/qoq-eslint-v9-js-vitest	JavaScript + Vitest
@ladamczyk/qoq-eslint-v9-js-vitest-rtl	JavaScript + Vitest + React Testing Library
@ladamczyk/qoq-eslint-v9-ts	TypeScript
@ladamczyk/qoq-eslint-v9-ts-react	TypeScript + React
@ladamczyk/qoq-eslint-v9-ts-jest	TypeScript + Jest
@ladamczyk/qoq-eslint-v9-ts-jest-rtl	TypeScript + Jest + React Testing Library
@ladamczyk/qoq-eslint-v9-ts-vitest	TypeScript + Vitest
@ladamczyk/qoq-eslint-v9-ts-vitest-rtl	TypeScript + Vitest + React Testing Library

Usage — spread the base config into your flat config and add your own files:

// ESM
import baseConfig from '@ladamczyk/qoq-eslint-v9-ts-react';

export default [
  {
    ...baseConfig,
    files: ['src/**/*.{ts,tsx}'],
  },
];

qoq-prettier

Base Prettier preset. Reference it directly in .prettierrc ("@ladamczyk/qoq-prettier") or import @ladamczyk/qoq-prettier/config and spread it into your own config.

qoq-prettier-with-json-sort

The same base preset plus automatic JSON key sorting. Used the same way — drop "@ladamczyk/qoq-prettier-with-json-sort" into .prettierrc or extend @ladamczyk/qoq-prettier-with-json-sort/config.

qoq-knip

Opinionated Knip configuration for detecting unused files, exports, and dependencies. Exports jsConfig, jsReactConfig, tsConfig, and tsReactConfig in both CommonJS and ESM for use in your Knip config file.

qoq-jscpd

A ready-made copy-paste detection config. Point JSCPD at the shipped config file:

jscpd -c ./node_modules/@ladamczyk/qoq-jscpd/index.json

qoq-stylelint-css

Stylelint config template for CSS.

qoq-stylelint-scss

Stylelint config template for SCSS.

qoq-utils

Shared internal helpers used across the QoQ packages.

check-engine

A standalone CLI that validates your project's engines.node setting, emitting suggestions or errors when the running Node version doesn't satisfy it. Run check-engine -h for options.
