ko-lint-config

2.2.22 verified Fri May 01 auth: no javascript

A shared lint configuration package from DTStack that bundles ESLint, Stylelint, and Prettier rules into a single dependency. Version 2.2.22 requires Node >=14 and ships TypeScript types. It enforces a specific code style (4-space indent, single quotes, no forced semicolons, optional trailing commas) designed for team consistency. Releases follow the ko monorepo's cadence. Differentiators: no configuration overhead, automatic formatting via pnpm lint-fix, and pre-defined rules that discourage overriding to maintain group style guide compliance.

Common errors

error Error: Cannot find module 'ko-lint-config' ↓

cause ko-lint-config not installed or require.resolve used without installing.

fix

Run npm install ko-lint-config --save-dev and ensure node_modules contains it.

error ESLint: Configuration for rule "indent" is invalid ↓

cause Overriding rules from ko-lint-config can cause incompatibility.

fix

Remove custom rule overrides and rely solely on ko-lint-config's defaults.

error Error: No configuration provided for stylelint ↓

cause Stylelint config not loaded; missing require.resolve for .stylelintrc.

fix

Add extends: [require.resolve('ko-lint-config/.stylelintrc')] to your .stylelintrc.js

error Error: Could not resolve 'ko-lint-config/.prettierrc' ↓

cause Using require.resolve on .prettierrc file when it's not a valid module export.

fix

Use const prettier = require('ko-lint-config/.prettierrc') without require.resolve.

Warnings

gotcha Do not use string literal 'ko-lint-config' in extends; use require.resolve() to avoid module resolution failures. ↓

fix Use require.resolve('ko-lint-config') in extends array.

deprecated The package expects ESLint <9 (flat config not supported). If you use ESLint 9+, this config will not work. ↓

fix Stick with ESLint 8 or migrate to a flat config manually.

breaking Major version bumps may change lint rules significantly without warning. Always review changelog before upgrading. ↓

fix Pin version and test lint output after upgrade.

gotcha Prettier config is spread, not extended. Using extends will cause errors. ↓

fix Use const prettier = require('ko-lint-config/.prettierrc'); module.exports = { ...prettier }

Install

npm install ko-lint-config

yarn add ko-lint-config

pnpm add ko-lint-config

Imports

ko-lint-config (ESLint config)
wrong
```
module.exports = { extends: ['ko-lint-config'] }
```
correct
```
module.exports = { extends: [require.resolve('ko-lint-config')] }
```
Use require.resolve to find the config file; string literal may resolve incorrectly in some environments.

Prettier config

wrong

module.exports = { extends: [require.resolve('ko-lint-config/.prettierrc')] }

correct

const prettier = require('ko-lint-config/.prettierrc'); module.exports = { ...prettier }

The .prettierrc file is a plain JS object, not a config with extends; spread it into your config.

Stylelint config

wrong

module.exports = { extends: ['ko-lint-config/.stylelintrc'] }

correct

module.exports = { extends: [require.resolve('ko-lint-config/.stylelintrc')] }

Same as ESLint: use require.resolve to ensure correct path resolution.

Quickstart

Install ko-lint-config, configure ESLint and Prettier via require.resolve, and add lint scripts.

pnpm add ko-lint-config -D

// .eslintrc.js
module.exports = {
  extends: [require.resolve('ko-lint-config')],
}

// .prettierrc.js
const prettier = require('ko-lint-config/.prettierrc')
module.exports = { ...prettier }

// package.json "scripts"
{
  "lint": "npx eslint './src/**/*.ts' './src/**/*.tsx'",
  "lint-fix": "npx eslint './src/**/*.ts' './src/**/*.tsx' --fix",
  "lint-css": "npx stylelint './src/**/*.scss' './src/**/*.css'",
  "lint-css-fix": "npx stylelint './src/**/*.scss' './src/**/*.css' --fix"
}

// Then run
pnpm lint-fix
