[SOLVED] error 'document' is not defined : eslint / React

error 'document' is not defined : eslint / React

I'm building a React app, with create-react-app.

I got the following error when running ESLint:
8:3 error 'document' is not defined no-undef.

My app runs without error, but I got this ESLint error in 2 files. See one of those .jsx files and my ESLint configuration.

index.jsx:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './index.css';

ReactDOM.render(
  <App />,
  document.getElementById('root'),
);

eslintrc.js:

module.exports = {
  "extends": "airbnb",
  "plugins": [
      "react",
      "jsx-a11y",
      "import"
  ],
  "env": {
    "jest": true
  }
};

How can I fix this ? For the moment I will simply ignore both files ... but I'd rather find a long term solution.

Solution

Add "browser": true your env to include global variables (like document, window, etc.)

See the ESLint environment documentation for more information.
