eslint-config-webpack

library4.9.5jsnpmunverified

Webpack's official ESLint configuration as a shareable config for projects using ESLint 9+ flat config. Version 4.9.5 requires Node >=20.9.0, ESLint >=9.28.0, and TypeScript >=4.8.4 <7.0.0. It provides TypeScript support, regexp rules, and JSDoc type formatting. Actively maintained by the Webpack team with frequent updates. Unlike generic configs like eslint-config-airbnb, it is tailored for webpack ecosystem projects.

Verified usage

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

default

✓ import config from 'eslint-config-webpack';

✗ const config = require('eslint-config-webpack');

Package uses ESM and provides a flat config object. CommonJS require() will not work because the package is ESM-only.

defineConfig

✓ import { defineConfig } from 'eslint/config';

defineConfig is from the eslint package itself, not from eslint-config-webpack.

Shows how to extend the webpack ESLint config in a flat config file with browser and Node globals.

// eslint.config.js import { defineConfig } from 'eslint/config'; import config from 'eslint-config-webpack'; import globals from 'globals'; export default defineConfig([ { extends: [config], languageOptions: { globals: { ...globals.browser, ...globals.node, }, }, }, ]);

Debug

Known issues

breakingv4.x introduced flat config (eslint.config.js) and dropped support for legacy .eslintrc files

fix

Migrate to eslint.config.js using extends with the provided config object.

affects: >=4.0.0

breakingRequires Node >=20.9.0

fix

Upgrade Node to v20.9.0 or later.

affects: >=4.9.0

breakingRequires ESLint >=9.28.0

fix

Upgrade ESLint to v9.28.0 or later.

affects: >=4.9.0

deprecatedTypeScript peer dependency: ^4.8.4 || ^5.0.0 || ^6.0.0 (future) but actual releases may enforce <7.0.0

fix

Install TypeScript matching the peer range; v4.8.4+ or v5.x is supported.

affects: >=4.8.5

gotchaThe default export is a flat config object, not an array. Using it directly without extending may cause linting issues if you need multiple configs.

fix

Wrap it in defineConfig or spread into an array when using multiple config objects.

affects: >=4.0.0

gotchaThe package does not include react preset by default; you may need to install additional plugins (e.g., eslint-plugin-react) if using React.

fix

Install react-related plugins and add them to your config manually.

affects: all

Errors

Common errors & fixes

Cannot find module 'eslint-config-webpack'

Package not installed or used in legacy ESLint config file (e.g., .eslintrc)

fix

Run 'npm i -D eslint-config-webpack' and use import in eslint.config.js flat config.

ESLint: Failed to load config "webpack" to extend from

Using string 'webpack' in extends instead of imported config object

fix

Import the config and use extends: [config] instead of extends: ['webpack'].

require() of ES Module /path/to/node_modules/eslint-config-webpack/index.js from ... not supported

Using CommonJS require() for an ESM-only package

fix

Use import() or set "type": "module" in your package.json.
