React specific linting rules for eslint


npm install eslint eslint-plugin-react --save-dev

It is also possible to install ESLint globally rather than locally (using npm install -g eslint). However, this is not recommended, and any plugins or shareable configs that you use must be installed locally in either case.

Configuration (legacy: .eslintrc*)

Use our preset to get reasonable defaults:

  "extends": [

If you are using the new JSX transform from React 17, extend react/jsx-runtime in your eslint config (add "plugin:react/jsx-runtime" to "extends") to disable the relevant rules.

You should also specify settings that will be shared across all the plugin rules. (More about eslint shared settings)

  "settings": {
    "react": {
      "createClass": "createReactClass", // Regex for Component Factory to use,
                                         // default to "createReactClass"
      "pragma": "React",  // Pragma to use, default to "React"
      "fragment": "Fragment",  // Fragment to use (may be a property of <pragma>), default to "Fragment"
      "version": "detect", // React version. "detect" automatically picks the version you have installed.
                           // You can also use `16.0`, `16.3`, etc, if you want to override the detected value.
                           // It will default to "latest" and warn if missing, and to "detect" in the future
      "flowVersion": "0.53" // Flow version
    "propWrapperFunctions": [
        // The names of any function used to wrap propTypes, e.g. `forbidExtraProps`. If this isn't set, any propTypes wrapped in a function will be skipped.
        {"property": "freeze", "object": "Object"},
        {"property": "myFavoriteWrapper"},
        // for rules that check exact prop wrappers
        {"property": "forbidExtraProps", "exact": true}
    "componentWrapperFunctions": [
        // The name of any function used to wrap components, e.g. Mobx `observer` function. If this isn't set, components wrapped by these functions will be skipped.
        "observer", // `property`
        {"property": "styled"}, // `object` is optional
        {"property": "observer", "object": "Mobx"},
        {"property": "observer", "object": "<pragma>"} // sets `object` to whatever value `settings.react.pragma` is set to
    "formComponents": [
      // Components used as alternatives to <form> for forms, eg. <Form endpoint={ url } />
      {"name": "SimpleForm", "formAttribute": "endpoint"},
      {"name": "Form", "formAttribute": ["registerEndpoint", "loginEndpoint"]}, // allows specifying multiple properties if necessary
    "linkComponents": [
      // Components used as alternatives to <a> for linking, eg. <Link to={ url } />
      {"name": "MyLink", "linkAttribute": "to"},
      {"name": "Link", "linkAttribute": ["to", "href"]}, // allows specifying multiple properties if necessary

If you do not use a preset you will need to specify individual rules and add extra configuration.

Add "react" to the plugins section.

  "plugins": [

Enable JSX support.

With eslint 2+

  "parserOptions": {
    "ecmaFeatures": {
      "jsx": true

Enable the rules that you would like to use.

  "rules": {
    "react/jsx-uses-react": "error",
    "react/jsx-uses-vars": "error",

Shareable configs


This plugin exports a recommended configuration that enforces React good practices.

To enable this configuration use the extends property in your .eslintrc config file:

  "extends": ["eslint:recommended", "plugin:react/recommended"]

See eslint documentation for more information about extending configuration files.


This plugin also exports an all configuration that includes every available rule. This pairs well with the eslint:all rule.

  "plugins": [
  "extends": ["eslint:all", "plugin:react/all"]

Note: These configurations will import eslint-plugin-react and enable JSX in parser options.

Configuration (new: eslint.config.js)

From v8.21.0, eslint announced a new config system. In the new system, .eslintrc* is no longer used. eslint.config.js would be the default config file name. In eslint v8, the legacy system (.eslintrc*) would still be supported, while in eslint v9, only the new system would be supported.

And from v8.23.0, eslint CLI starts to look up eslint.config.js. So, if your eslint is >=8.23.0, you're 100% ready to use the new config system.

You might want to check out the official blog posts,

and the official docs.


The default export of eslint-plugin-react is a plugin object.

const react = require('eslint-plugin-react');
const globals = require('globals');

module.exports = [
    files: ['**/*.{js,jsx,mjs,cjs,ts,tsx}'],
    plugins: {
    languageOptions: {
      parserOptions: {
        ecmaFeatures: {
          jsx: true,
      globals: {
    rules: {
      // ... any rules you want
      'react/jsx-uses-react': 'error',
      'react/jsx-uses-vars': 'error',
    // ... others are omitted for brevity

Configuring shared settings

Refer to the official docs.

The schema of the settings.react object would be identical to that of what's already described above in the legacy config section.

Shareable configs

There're also 3 shareable configs.

  • eslint-plugin-react/configs/all
  • eslint-plugin-react/configs/recommended
  • eslint-plugin-react/configs/jsx-runtime

If your eslint.config.js is ESM, include the .js extension (e.g. eslint-plugin-react/recommended.js). Note that the next semver-major will require omitting the extension for these imports.

Note: These configurations will import eslint-plugin-react and enable JSX in languageOptions.parserOptions.

In the new config system, plugin: protocol(e.g. plugin:react/recommended) is no longer valid. As eslint does not automatically import the preset config (shareable config), you explicitly do it by yourself.

const reactRecommended = require('eslint-plugin-react/configs/recommended');

module.exports = [
  reactRecommended, // This is not a plugin object, but a shareable config object

You can of course add/override some properties.

Note: Our shareable configs does not preconfigure files or languageOptions.globals. For most of the cases, you probably want to configure some properties by yourself.

const reactRecommended = require('eslint-plugin-react/configs/recommended');
const globals = require('globals');

module.exports = [
    files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
    languageOptions: {
      globals: {

The above example is same as the example below, as the new config system is based on chaining.

const reactRecommended = require('eslint-plugin-react/configs/recommended');
const globals = require('globals');

module.exports = [
    files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
    files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
    languageOptions: {
      globals: {
