eslint-config-xo

ESLint shareable config for XO

See eslint-plugin-unicorn for some additional useful rules.

Use the XO issue tracker instead of this one.

Install

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

// eslint.config.js
import xo from 'eslint-config-xo';

export default [
	...xo,
];

This package also exposes eslint-config-xo/browser if you're in the browser:

import xoBrowser from 'eslint-config-xo/browser';

export default [
	...xoBrowser,
];

This package also exposes eslint-config-xo/space if you're in favor of 2-space indent:

import xoSpace from 'eslint-config-xo/space';

export default [
	...xoSpace,
];

This package also exposes eslint-config-xo/space/browser if you're in favor of 2-space indent and in browser:

import xoSpaceBrowser from 'eslint-config-xo/space/browser';

export default [
	...xoSpaceBrowser,
];

XO is an ESLint wrapper with great defaults.

Here are some reason why you should use the XO CLI instead of this config:

XO comes bundled with this config.
Beautiful output.
Bundles many useful plugins, like eslint-plugin-unicorn, eslint-plugin-import, eslint-plugin-ava, and more.
No need to specify file paths to lint. It will lint all JS files except commonly ignored paths.
Super simple to add XO to a project with $ npm init xo.
Specify indent and semicolon preferences easily without messing with the rule config.
Config/rule overrides per files/globs.
Can open all files with errors at the correct line in your editor. (See the --open flag)
The editor plugins are IMHO better than the ESLint ones. (Subjective)

tl;dr You miss out on a lot by just using this config.
