    eslint-config-expo

    Shared ESLint configs for Node, Web, React Native, and Expo projects.

    Installation

    yarn add --dev eslint-config-expo

    You will also need to install eslint and prettier:

    yarn add --dev eslint prettier

    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": "expo"
      }
    }

    .eslintrc.js

    module.exports = {
      extends: 'expo',
    };

    Customizing Prettier

    If you would like to customize the Prettier settings, create a file named .prettierrc in your project directory. This file must declare a Prettier configuration like this:

    {
      "printWidth": 100,
      "tabWidth": 2,
      "singleQuote": true,
      "jsxBracketSameLine": true,
      "trailingComma": "es5"
    }

    Support for Different Platforms

    There are several configs for different platforms. They are:

    • expo: the basic config for JavaScript projects for which there isn't a more specific config
    • expo/native: the config for React Native projects, including Expo projects, with support for React and JSX
    • expo/web: the config for code that runs in web browsers, with support for React and JSX
    • expo/node: the config for code that runs in Node

    For an Expo project, your configuration might look like this:

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

    You also can extend multiple configs, which is useful for projects that span several platforms:

    "eslintConfig": {
      "extends": ["expo/node", "expo/web"]
    }

    Install

    npm i eslint-config-expo
