ESLint configuration used by Create React App

readme

eslint-config-react-app

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

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 the following steps.

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

npm install --save-dev eslint-config-react-app babel-eslint@9.x eslint@5.x eslint-plugin-flowtype@2.x eslint-plugin-import@2.x eslint-plugin-jsx-a11y@6.x eslint-plugin-react@7.x

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

{
  "extends": "react-app"
}

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

Accessibility Checks

The following rules from the eslint-plugin-jsx-a11y plugin are activated:

If you want to enable even more accessibility rules, you can create an .eslintrc.json file in the root of your project with this content:

{
  "extends": ["react-app", "plugin:jsx-a11y/recommended"],
  "plugins": ["jsx-a11y"]
}

However, if you are using Create React App and have not ejected, any additional rules will only be displayed in the IDE integrations, but not in the browser or the terminal.

5.0.0 (2021-12-14)

Create React App 5.0 is a major release with several new features and the latest version of all major dependencies.

Thanks to all the maintainers and contributors who worked so hard on this release! 🙌

Highlights

  • webpack 5 (#11201)
  • Jest 27 (#11338)
  • ESLint 8 (#11375)
  • PostCSS 8 (#11121)
  • Fast Refresh improvements and bug fixes (#11105)
  • Support for Tailwind (#11717)
  • Improved package manager detection (#11322)
  • Unpinned all dependencies for better compatibility with other tools (#11474)
  • Dropped support for Node 10 and 12

Migrating from 4.0.x to 5.0.0

Inside any created project that has not been ejected, run:

npm install --save --save-exact react-scripts@5.0.0

or

yarn add --exact react-scripts@5.0.0

NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running npm install (or yarn) if you encounter errors after upgrading.

If you previously ejected but now want to upgrade, one common solution is to find the commits where you ejected (and any subsequent commits changing the configuration), revert them, upgrade, and later optionally eject again. It’s also possible that the feature you ejected for is now supported out of the box.

Breaking Changes

Like any major release, `react-scripts@5.0.0` contains a number of breaking changes. We expect that they won't affect every user, but we recommend you look over this section to see if something is relevant to you. If we missed something, please file a new issue.

Dropped support for Node 10 and 12 Node 10 reached End-of-Life in April 2021 and Node 12 will be End-of-Life in April 2022. Going forward we will only support the latest LTS release of Node.js.
