create-react-app doesn't work with eslint-config-airbnb after eject

I’m using CRA v1.4.1.

1. create-react-app testapp
2. npm eject
3. install https://www.npmjs.com/package/eslint-config-airbnb
4. add eslint with the following config:

{
  "root": true,
  "extends": "airbnb",
  "plugins": ["react"],
  "parserOptions": {
    "ecmaVersion": 6,
    "sourceType": "module",
    "ecmaFeatures": {
      "jsx": true
    }
  },
  "env": {
      "es6": true,
      "browser": true
  },
  "parser": "babel-eslint",
  "rules": {
    "strict": 0
  }
}

The build fails with several errors (JSX not allowed in files with extension ‘.js’, and many in registerServiceWorker.js).

The default react-app config is very limited (eg. it doesn’t enforce semicolons) and airbnb is the de facto standard so would be cool if CRA can be fixed to comply to it by default.

This is still an issue without ejecting, so I think it is an issue with CRA.

This isn’t a concern of CRA; if you’ve ejected it’s up to you to fix your ESLint configuration or errors.

Sorry!

Also, react-app config is strictly for finding errors – we do not enforce style. You should not use eslint to enforce style. Use a tool like Prettier to enforce style.
