Shareable stylelint config for React Native CSS modules

Install stylelint-config-react-native-css-modules (and stylelint + stylelint-react-native, if you haven't done so yet):

yarn add stylelint stylelint-react-native stylelint-config-react-native-css-modules --dev

or

npm install stylelint stylelint-react-native stylelint-config-react-native-css-modules --save-dev

Create the .stylelintrc config file (or open the existing one) and extend stylelint-config-react-native-css-modules config.

{
  "extends": "stylelint-config-react-native-css-modules",
  "rules": {
    "selector-class-pattern": "^[a-z][a-zA-Z0-9]*$"
  }
}

By default the config is for React Native only, but if you want to share the styles between React Native and Web, extend the stylelint-config-react-native-css-modules/web config instead. This turns some of the errors to warnings to ensure compatibility with Web.

{
  "extends": "stylelint-config-react-native-css-modules/web",
  "rules": {
    "selector-class-pattern": "^[a-z][a-zA-Z0-9]*$"
  }
}

If you want to turn off any of the included errors or warnings, set the rule's value to null:

{
  "extends": "stylelint-config-react-native-css-modules/web",
  "rules": {
    "react-native/font-weight-no-ignored-values": null
  }
}
