eslint-config-react-app-extra

This package includes the shareable ESLint configuration used by Create React App.
Please refer to its documentation:

• Getting Started – How to create a new app.
• User Guide – How to develop apps bootstrapped with Create React App.

Usage in Create React App Projects

The easiest way to use this configuration is with Create React App, which includes it by default. You don’t need to install it separately in Create React App projects.

Usage Outside of Create React App

If you want to use this ESLint configuration in a project not built with Create React App, you can install it with following steps.

First, install this package, ESLint and the necessary plugins.

npm install --save-dev eslint-config-react-app-extra babel-eslint@7.1.1 eslint@3.16.1 eslint-plugin-flowtype@2.21.0 eslint-plugin-import@2.0.1 eslint-plugin-jsx-a11y@4.0.0 eslint-plugin-react@6.4.1

Then create a file named .eslintrc with following contents in the root folder of your project:

{
  "extends": "react-app-extra"
}

That's it! You can override the settings from eslint-config-react-app-extra by editing the .eslintrc file. Learn more about configuring ESLint on the ESLint website.
