React specific linting rules for ESLint

Installation

Install ESLint either locally or globally.

$ npm install eslint --save-dev

If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally.

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

Configuration

Add plugins section and specify ESLint-plugin-React as a plugin.

{
  "plugins": [
    "react"
  ]
}

You can also specify some settings that will be shared across all the plugin rules.

{
  "settings": {
    "react": {
      "createClass": "createReactClass", // Regex for Component Factory to use, default to "createReactClass"
      "pragma": "React",  // Pragma to use, default to "React"
      "version": "15.0" // React version, default to the latest React stable release
    },
    "propWrapperFunctions": [ "forbidExtraProps" ] // The names of any functions used to wrap the propTypes object, such as `forbidExtraProps`. If this isn't set, any propTypes wrapped in a function will be skipped.
  }
}

If it is not already the case you must also configure ESLint to support JSX.

With ESLint 1.x.x:

{
  "ecmaFeatures": {
    "jsx": true
  }
}

With ESLint 2.x.x or 3.x.x:

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

Finally, enable all of the rules that you would like to use. Use our preset to get reasonable defaults quickly, and/or choose your own:

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

Shareable configurations

Recommended

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.

The rules enabled in this configuration are:

All

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

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

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