ESLint Configuration

Website | Configure ESLint | Rules | Contributing | Twitter | Discord | Mastodon

Contains the ESLint configuration used for projects maintained by the ESLint team.

Installation

You can install ESLint using npm:

npm install eslint --save-dev

Then install this configuration:

npm install eslint-config-eslint --save-dev

Usage

ESM ("type":"module") projects

In your eslint.config.js file, add:

import eslintConfigESLint from "eslint-config-eslint";

export default [
    ...eslintConfigESLint
];

Note: This configuration array contains configuration objects with the files property.

• files: ["**/*.js"]: ESM-specific configurations.
• files: ["**/*.cjs"]: CommonJS-specific configurations.

CommonJS projects

In your eslint.config.js file, add:

const eslintConfigESLintCJS = require("eslint-config-eslint/cjs");

module.exports = [
    ...eslintConfigESLintCJS
];

Base config

Note that the above configurations are intended for files that will run in Node.js. For files that will not run in Node.js, you should use the base config.

Here's an example of an eslint.config.js file for a website project with scripts that run in browser and CommonJS configuration files and tools that run in Node.js:

const eslintConfigESLintBase = require("eslint-config-eslint/base");
const eslintConfigESLintCJS = require("eslint-config-eslint/cjs");

module.exports = [
    ...eslintConfigESLintBase.map(config => ({
        ...config,
        files: ["scripts/*.js"]
    })),
    ...eslintConfigESLintCJS.map(config => ({
        ...config,
        files: ["eslint.config.js", ".eleventy.js", "tools/*.js"]
    }))
];
