eslint-config-eslint

library14.0.0jsnpmunverified

eslint-config-eslint is the official ESLint shareable configuration used by ESLint projects themselves. Version 14.0.0 ships TypeScript types and requires ESLint ^10.0.0 as a peer dependency. Released as part of the ESLint monorepo, it follows ESLint's major release cadence. It provides multiple config presets: default (ESM), CJS, base (for non-Node.js files), and formatting. Unlike generic configs like eslint-config-standard, this config is tailored for internal ESLint development, enforcing strict rules expected in the ESLint codebase. It is not intended for general use unless mirroring ESLint's own style.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default (eslintConfigESLint)

✓ import eslintConfigESLint from 'eslint-config-eslint'

✗ const eslintConfigESLint = require('eslint-config-eslint')

Default export only works with ESM (type: module). For CommonJS, use require('eslint-config-eslint/cjs').

eslintConfigESLintCJS

✓ const eslintConfigESLintCJS = require('eslint-config-eslint/cjs')

✗ import eslintConfigESLintCJS from 'eslint-config-eslint/cjs'

CommonJS entry point; not available as ESM since it uses require internally.

eslintConfigESLintBase

✓ import eslintConfigESLintBase from 'eslint-config-eslint/base'

Base config for non-Node.js files; available in ESM and CJS (require).

eslintConfigESLintFormatting

✓ import eslintConfigESLintFormatting from 'eslint-config-eslint/formatting'

Optional formatting config; add separately if formatting rules are desired.

Shows a minimal eslint.config.js using the default ESM config from eslint-config-eslint with defineConfig.

// eslint.config.js export default [ { files: ["**/*.js"], languageOptions: { sourceType: "module", ecmaVersion: "latest" }, plugins: {}, rules: { semi: "error", "no-unused-vars": "error" } } ]; // Install // npm install eslint@^10.0.0 eslint-config-eslint@^14.0.0 -D // Use with ESLint config: // eslint.config.js // import { defineConfig } from "eslint/config"; // import eslintConfigESLint from "eslint-config-eslint"; // export default defineConfig([eslintConfigESLint]);

Debug

Known issues

breakingv14 requires ESLint ^10.0.0 as a peer dependency; ESLint v9 is not compatible.

fix

Upgrade ESLint to ^10.0.0. If staying on ESLint v9, use eslint-config-eslint@13.x.

affects: >=14.0.0

gotchaDefault export is ESM-only; using require() on the main entry will throw.

fix

Use import for ESM projects, or require('eslint-config-eslint/cjs') for CommonJS.

affects: >=14.0.0

deprecatedESLint's flat config (eslint.config.js) is now the only supported format; legacy .eslintrc is not used.

fix

Migrate to eslint.config.js using flat config. See ESLint migration guide.

affects: >=14.0.0

gotchaThe base config (eslint-config-eslint/base) does not include formatting rules; you must opt-in.

fix

Add eslintConfigESLintFormatting from 'eslint-config-eslint/formatting' if formatting rules are needed.

affects: >=14.0.0

breakingv14 drops support for Node.js versions below ^20.19.0 || ^22.13.0 || >=24.

fix

Ensure Node.js version meets the engine requirement.

affects: >=14.0.0

Errors

Common errors & fixes

Cannot find module 'eslint-config-eslint'

Package not installed or incorrect import path (CommonJS using default instead of /cjs).

fix

npm install eslint-config-eslint -D. If using CommonJS, use require('eslint-config-eslint/cjs').

Failed to load config "eslint-config-eslint" to extend from.

Using legacy .eslintrc format with extends; eslint-config-eslint v14 only supports flat config.

fix

Create eslint.config.js and use import/require as shown in documentation.

Cannot use import statement outside a module

ESM import used in a CommonJS project without type: module.

fix

Set "type": "module" in package.json, or use require('eslint-config-eslint/cjs').

Parsing error: 'import' and 'export' may appear only with 'sourceType: "module"'

Default config expects sourceType: "module" for .js files; project uses CommonJS.

fix

Use the CJS config (require('eslint-config-eslint/cjs')) for CommonJS files.
