ESLint-plugin-React

React specific linting rules for ESLint

Installation

Install ESLint either locally or globally.

$ npm install eslint

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

$ npm install eslint-plugin-react

Configuration

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

{
  "plugins": [
    "react"
  ]
}

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

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

Finally, enable all of the rules that you would like to use.
