# eslint-config-airbnb-base
|
|
|
|
[](http://badge.fury.io/js/eslint-config-airbnb-base)
|
|
|
|
This package provides Airbnb's base JS .eslintrc (without React plugins) as an extensible shared config.
|
|
|
|
## Usage
|
|
|
|
We export two ESLint configurations for your usage.
|
|
|
|
### eslint-config-airbnb-base
|
|
|
|
Our default export contains all of our ESLint rules, including ECMAScript 6+. It requires `eslint` and `eslint-plugin-import`.
|
|
|
|
If you use yarn, run `npm info "eslint-config-airbnb-base@latest" peerDependencies` to list the peer dependencies and versions, then run `yarn add --dev <dependency>@<version>` for each listed peer dependency. See below for npm instructions.
|
|
|
|
1. Install the correct versions of each package, which are listed by the command:
|
|
|
|
```sh
|
|
npm info "eslint-config-airbnb-base@latest" peerDependencies
|
|
```
|
|
|
|
Linux/OSX users can run
|
|
```sh
|
|
(
|
|
export PKG=eslint-config-airbnb-base;
|
|
npm info "$PKG@latest" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs npm install --save-dev "$PKG@latest"
|
|
)
|
|
```
|
|
|
|
Which produces and runs a command like:
|
|
|
|
```sh
|
|
npm install --save-dev eslint-config-airbnb-base eslint@^#.#.# eslint-plugin-import@^#.#.#
|
|
```
|
|
|
|
Windows users can either install all the peer dependencies manually, or use the [install-peerdeps](https://github.com/nathanhleung/install-peerdeps) cli tool.
|
|
|
|
```sh
|
|
npm install -g install-peerdeps
|
|
install-peerdeps --dev eslint-config-airbnb-base
|
|
```
|
|
|
|
The cli will produce and run a command like:
|
|
|
|
```sh
|
|
npm install --save-dev eslint-config-airbnb-base eslint@^#.#.# eslint-plugin-import@^#.#.#
|
|
```
|
|
|
|
2. Add `"extends": "airbnb-base"` to your .eslintrc.
|
|
|
|
### eslint-config-airbnb-base/legacy
|
|
|
|
Lints ES5 and below. Requires `eslint` and `eslint-plugin-import`.
|
|
|
|
1. Install the correct versions of each package, which are listed by the command:
|
|
|
|
```sh
|
|
npm info "eslint-config-airbnb-base@latest" peerDependencies
|
|
```
|
|
|
|
Linux/OSX users can run
|
|
```sh
|
|
(
|
|
export PKG=eslint-config-airbnb-base;
|
|
npm info "$PKG" peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs npm install --save-dev "$PKG"
|
|
)
|
|
```
|
|
|
|
Which produces and runs a command like:
|
|
|
|
```sh
|
|
npm install --save-dev eslint-config-airbnb-base eslint@^3.0.1 eslint-plugin-import@^1.10.3
|
|
```
|
|
|
|
2. Add `"extends": "airbnb-base/legacy"` to your .eslintrc
|
|
|
|
See [Airbnb's overarching ESLint config](https://npmjs.com/eslint-config-airbnb), [Airbnb's Javascript styleguide](https://github.com/airbnb/javascript), and the [ESlint config docs](http://eslint.org/docs/user-guide/configuring#extending-configuration-files) for more information.

|
|
## Improving this config
|
|
|
|
Consider adding test cases if you're making complicated rules changes, like anything involving regexes. Perhaps in a distant future, we could use literate programming to structure our README as test cases for our .eslintrc?
|
|
|
|
You can run tests with `npm test`.
|
|
|
|
You can make sure this module lints with itself using `npm run lint`.
