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 eslint --global). However, this is not recommended, and any plugins or shareable configs that you use must be installed locally in either case.


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": "Form", "formAttribute": "endpoint"}
    "linkComponents": [
      // Components used as alternatives to <a> for linking, eg. <Link to={ url } />
      {"name": "Link", "linkAttribute": "to"}

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",

Other useful plugins

Shareable configurations


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.
