eslint-config-slalom ⛷️

An eslint config built with prettier in mind, heavily based off of eslint-config-xo.

Install

yarn add eslint-config-slalom --dev

Usage

In package.json

{
  "name": "my-project",
  "eslintConfig": {
    "extends": "slalom"
  }
}

Or in .eslintrc

{
  "extends": "slalom"
}

Why another eslint config?

I wanted an eslint config to fit the following criteria:

• doesn't require me to install multiple eslint plugins (e.g. eslint-config-airbnb)
• doesn't require me to have unnecessary / unneeded plugins just to turn things off (e.g. eslint-config-prettier)
• had a minimal, clean, but reasonable ruleset that enforces readable code (which is why this is based off of xo)
• ...but also doesn't have extra/separate configs or plugins to extend certain rules (e.g. xo/react, xo/space, etc.)
• reaches code-quality rules and leaves formatting to Prettier

This config:

• contains no rules that conflict with Prettier, nor stylistic rules you can set to your liking with Prettier
• does not require any other eslint config or plugin
• focuses on readable code and code-quality rules
• covers react and next-generation javascript

Recommended configuration

I use this with eslint-plugin-prettier to set formatting rules. I also recommend eslint-plugin-unicorn which checks a nice set of rules.

{
  "parser": "babel-eslint",
  "parserOptions": {
    "ecmaVersion": 6,
    "sourceType": "module"
  },
  "extends": ["slalom"],
  "plugins": ["prettier", "react", "unicorn"],
  "rules": {
    "prettier/prettier": [
      "error",
      {
        "singleQuote": true,
        "semi": false
      }
    ]
  }
}
