React Native ESLINT config

react_native_eslint.md

eslint-config-universe

Shared ESLint configs for Node, Web, and universal Expo projects.

Installation

yarn add --dev eslint-config-universe eslint prettier @typescript-eslint/eslint-plugin @typescript-eslint/parser

Usage

Import this config into your own ESLint configuration using the extends option. ESLint checks both package.json and .eslintrc.* files for its configuration:

package.json

{
  "eslintConfig": {
    "extends": "universe/native"
  }
}

.eslintrc.js

// Choose from universe/native, universe/node, universe/web
module.exports = {
  extends: 'universe/native',
};

Customizing Prettier

If you would like to customize the Prettier settings, create a file named .prettierrc in your project directory. An example of Prettier configuration file:

{
  "semi": false,
  "tabWidth": 2,
  "singleQuote": true,
  "bracketSameLine": true,
  "trailingComma": "es5"
}
