Framework (OSS). Set up Tailwind CSS v4 in Expo with react-native-css and NativeWind v5 for universal styling
This guide covers setting up Tailwind CSS v4 in Expo using react-native-css and NativeWind v5 for universal styling across iOS, Android, and Web.
This setup uses:
Add resolutions for lightningcss compatibility:
Create or update metro.config.js:
Create postcss.config.mjs:
Create src/global.css:
With Tailwind v4 and NativeWind v5, you do NOT need a babel.config.js for Tailwind. Remove any NativeWind babel presets if present:
Since react-native-css requires explicit CSS element wrapping, create reusable components:
src/tw/index.tsx)src/tw/image.tsx)src/tw/animated.tsx)Import CSS-wrapped components from your tw directory:
Add custom theme variables in your global.css using @theme:
Use platform media queries for platform-specific styling:
Create a CSS file for Apple semantic colors:
Then use in components:
Use the useCSSVariable hook:
@tailwindcss/postcss instead of tailwindcss@import "tailwindcss/..." instead of @tailwind directives@theme in CSS instead of tailwind.config.jsuseCssElement for className supportwithNativewind with different options (inlineVariables: false)useCssElementwithNativewind appliedplatformColor() in @media ios blockslight-dark() for web/AndroidAdd className to component props:
If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve:
Only submit when you have something specific and actionable to report. Include as much relevant context as possible.
