prettier-plugin-eslint

library1.0.2jsnpmunverified

Automatically integrates ESLint's auto-fix functionality into Prettier formatting, so that running Prettier also applies ESLint --fix. Version 1.0.2 is the current stable release; the plugin runs ESLint on .js files before Prettier formatting. Compared to alternatives like prettier-eslint, this is a Prettier plugin (not a separate CLI) and requires no extra configuration beyond installation. It assumes ESLint configuration is in an .eslintrc file (package.json support planned).

Verified usage

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

plugin

✓ // No import needed; install and it auto-registers with Prettier.

✗ import plugin from 'prettier-plugin-eslint'

This is a Prettier plugin; installation alone activates it. No JavaScript import required.

default

✓ // In .prettierrc: { "plugins": ["prettier-plugin-eslint"] }

✗ require('prettier-plugin-eslint')

Configure via Prettier's plugins option, not a direct require.

use with Prettier API

✓ const prettier = require('prettier'); await prettier.format(code, { parser: 'babel', plugins: ['prettier-plugin-eslint'] });

✗ const plugin = require('prettier-plugin-eslint');

Pass the plugin name in the options object when using Prettier programmatically.

Install prettier-plugin-eslint, configure .prettierrc, ESLint rule for no semicolons, and run Prettier to see autofix.

npm install --save-dev prettier prettier-plugin-eslint eslint echo '{"plugins": ["prettier-plugin-eslint"]}' > .prettierrc echo '{"rules": {"semi": ["error", "never"]}}' > .eslintrc.json # Create a test file echo 'const x = 1;' > test.js # Run Prettier npx prettier --write test.js # Verify that semicolon is removed (ESLint --fix applied) cat test.js # should output: const x = 1

Debug

Known issues

gotchaPlugin only processes .js files; other file types (ts, json, css) are not linted.

fix

Use separate plugins (e.g., prettier-plugin-tslint) for non-JS files.

affects: >=1.0.0

gotchaThe plugin runs ESLint before Prettier; formatting from ESLint may conflict with Prettier styles.

fix

Ensure ESLint rules are compatible with Prettier output; use eslint-config-prettier to disable conflicting rules.

affects: >=1.0.0

gotchaESLint configuration must be in .eslintrc file (JSON, YAML, or JS); package.json 'eslintConfig' key is not supported.

fix

Move ESLint config to an .eslintrc file or wait for package.json support.

affects: >=1.0.0 <2.0.0

gotchaThe plugin does not support ESLint's --fix-to-stdout or other CLI flags.

fix

Run ESLint directly if custom fix behavior is needed.

affects: >=1.0.0

breakingVersion 1.0.0 required Prettier >= 2.0. Older Prettier versions are incompatible.

fix

Upgrade Prettier to version 2.0 or later.

affects: >=1.0.0

Missing ESLint config file; package.json eslintConfig not supported.

fix

Create an .eslintrc file (e.g., .eslintrc.json) in project root.

Cannot read property 'config' of undefined
