library4.2.11jsnpmunverified

ESLint shareable config that bundles ESLint, Prettier, and npm-package-json-lint into a single dependency. Current stable version 4.2.11 includes flat config support for ESLint v9+, TypeScript parsing via @typescript-eslint, import sorting with simple-import-sort, unused imports removal, and separate Prettier/npm-package-json-lint configs. Differentiates from alternatives like eslint-config-prettier by also providing opinionated lint rules (double quotes, semicolons, trailing commas) and optional strict TypeScript TSConfig. Offers two package lint profiles: one for libraries (requiring version range) and one for applications (allowing fixed versions).

Code

Verified usage

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

default export (config array)

✓ import config from 'eslint-config-plus-prettier'

✗ const config = require('eslint-config-plus-prettier')

ESM-only since v4; requires ESLint flat config. For CommonJS, rename file to eslint.config.cjs and use require().

Prettier config reference

✓ add '"prettier": "eslint-config-plus-prettier/prettier"' to package.json

✗ import prettier from 'eslint-config-plus-prettier/prettier'

This is not a JavaScript export; it's a JSON config path used in package.json.

npm-package-json-lint config

✓ In .npmpackagejsonlintrc.json: { "extends": "eslint-config-plus-prettier/packagelint" }

✗ import packagelint from 'eslint-config-plus-prettier/packagelint'

For server/applications use 'eslint-config-plus-prettier/packagelint/server'.

TypeScript TSConfig extends

✓ In tsconfig.json: { "extends": "eslint-config-plus-prettier/tsconfig" }

✗ import tsconfig from 'eslint-config-plus-prettier/tsconfig'

This extends a JSON file via the 'extends' field in tsconfig, not an import.

Install the package, set up ESLint flat config, add Prettier reference in package.json, and add scripts for linting and formatting.

# Install as devDependency npm install --save-dev --save-exact eslint-config-plus-prettier # package.json { "type": "module", "scripts": { "format": "prettier --write .", "format:check": "prettier --check .", "lint": "eslint --fix", "lint:check": "eslint", "package:lint": "npx npm-package-json-lint ." } } # eslint.config.js import config from "eslint-config-plus-prettier"; export default [config]; # package.json (add prettier config) { "prettier": "eslint-config-plus-prettier/prettier" }

Debug

Known issues

breakingv4 requires ESLint v9+ with flat config; does not support .eslintrc files.

fix

Upgrade to ESLint v9 and use eslint.config.js (flat config).

affects: >=4.0.0

breakingv4 is ESM-only; CommonJS projects must rename config file to eslint.config.cjs or use dynamic import.

fix

Rename eslint.config.js to eslint.config.cjs and use module.exports or require().

affects: >=4.0.0

deprecatedv3 uses legacy .eslintrc format; v4 uses flat config. v3 may stop receiving updates.

fix

Update to v4 and migrate to flat config.

affects: >=3.0.0 <4.0.0

gotchaPrettier config reference in package.json is a string path, not a require/import.

fix

Use "prettier": "eslint-config-plus-prettier/prettier" in package.json.

affects: all

gotchanpm-package-json-lint config must be in .npmpackagejsonlintrc.json, not via import.

fix

Create a .npmpackagejsonlintrc.json file with extends field.

affects: all

gotchaTypeScript support requires a separate tsconfig.json that extends the provided config; ESLint config already handles TS parsing.

fix

Create tsconfig.json with extends: 'eslint-config-plus-prettier/tsconfig'.

affects: all
