# eslint-config-xo
> ESLint [shareable config](https://eslint.org/docs/developer-guide/shareable-configs.html) for [XO](https://github.com/xojs/xo)
This is for advanced users. [You probably want to use XO directly.](#use-the-xo-cli-instead)
See [eslint-plugin-unicorn](https://github.com/sindresorhus/eslint-plugin-unicorn) for some additional useful rules.
**Use the [XO issue tracker](https://github.com/xojs/xo/issues) instead of this one.**
## Install
```
$ npm install --save-dev eslint-config-xo
```
## Usage
Add some ESLint config to your `package.json`:
```json
{
"name": "my-awesome-project",
"eslintConfig": {
"extends": "xo"
}
}
```
Or to `.eslintrc`:
```json
{
"extends": "xo"
}
```
Supports parsing ES2015+, but doesn't enforce it by default.
This package also exposes [`xo/browser`](browser.js) if you're in the browser:
```json
{
"extends": "xo/browser"
}
```
## Use the XO CLI instead
XO is an ESLint wrapper with great defaults.
Here are some reason why you should use the [XO CLI](https://github.com/xojs/xo) instead of this config:
- XO comes bundled with this config.
- [Beautiful output.](https://github.com/sindresorhus/eslint-formatter-pretty)
- Bundles many useful plugins, like [`eslint-plugin-unicorn`](https://github.com/sindresorhus/eslint-plugin-unicorn), [`eslint-plugin-import`](https://github.com/benmosher/eslint-plugin-import), [`eslint-plugin-ava`](https://github.com/avajs/eslint-plugin-ava), and more.
- No need to specify file paths to lint. It will lint all JS files except [commonly ignored paths](https://github.com/xojs/xo#ignores).
- Super simple to add XO to a project with [`$ npm init xo`](https://github.com/xojs/create-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](https://github.com/xojs/xo#editor-plugins) are IMHO better than the ESLint ones. *(Subjective)*
tl;dr You miss out on a lot by just using this config.
