NativeWind — Tailwind CSS for React Native

Overview

NativeWind uses Tailwind CSS as a universal styling language for React Native. Write className strings with Tailwind utility classes and NativeWind compiles them to React Native StyleSheet objects at build time. v4 (current) targets Expo SDK 52+ and uses CSS variables for theming, making dark mode and custom themes effortless.

When to Use

• React Native or Expo projects where your team already knows Tailwind
• Universal apps sharing Tailwind styles across web (Next.js) and native
• Replacing StyleSheet objects with utility-first classes for faster iteration
• Expo projects needing dark mode with minimal setup
• Teams migrating from a web Tailwind codebase to add a native app

Installation / Setup

# NativeWind v4 with Expo
npx expo install nativewind tailwindcss react-native-reanimated react-native-safe-area-context

# Run the setup command (configures babel, metro, tsconfig)
npx expo customize metro.config.js

// tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    './app/**/*.{js,jsx,ts,tsx}',
    './components/**/*.{js,jsx,ts,tsx}',
  ],
  presets: [require('nativewind/preset')],
  theme: {
    extend: {
      colors: {
        brand: '#6366f1',
      },
    },
  },
};

// metro.config.js
const { getDefaultConfig } = require('expo/metro-config');
const { withNativeWind } = require('nativewind/metro');

const config = getDefaultConfig(__dirname);
module.exports = withNativeWind(config, { input: './global.css' });

/* global.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

// app/_layout.tsx
import '../global.css';

// nativewind-env.d.ts (TypeScript support)
/// <reference types="nativewind/types" />

Key Patterns

Basic className Usage

import { View, Text, Pressable } from 'react-native';

function Button({ label, onPress }: { label: string; onPress: () => void }) {
  return (
    <Pressable
      className="bg-indigo-600 rounded-xl px-6 py-3 active:opacity-70"
      onPress={onPress}
    >
      <Text className="text-white font-semibold text-base text-center">
        {label}
      </Text>
    </Pressable>
  );
}

function Card({ title, body }: { title: string; body: string }) {
  return (
    <View className="bg-white dark:bg-zinc-900 rounded-2xl p-4 shadow-sm mx-4 my-2">
      <Text className="text-zinc-900 dark:text-white text-lg font-bold mb-1">
        {title}
      </Text>
      <Text className="text-zinc-500 dark:text-zinc-400 text-sm leading-relaxed">
        {body}
      </Text>
    </View>
  );
}

Dark Mode

import { useColorScheme } from 'nativewind';

function ThemeToggle() {
  const { colorScheme, toggleColorScheme } = useColorScheme();

  return (
    <Pressable
      className="flex-row items-center gap-2 p-3 rounded-lg bg-zinc-100 dark:bg-zinc-800"
      onPress={toggleColorScheme}
    >
      <Text className="text-zinc-900 dark:text-white">
        {colorScheme === 'dark' ? 'Light Mode' : 'Dark Mode'}
      </Text>
    </Pressable>
  );
}

Conditional Classes (clsx/cn)

import { cn } from '@/lib/utils'; // clsx + twMerge helper
import { View, Text } from 'react-native';

type BadgeVariant = 'default' | 'success' | 'warning' | 'error';

function Badge({ label, variant = 'default' }: { label: string; variant?: BadgeVariant }) {
  return (
    <View
      className={cn(
        'px-2 py-0.5 rounded-full self-start',
        variant === 'default' && 'bg-zinc-100 dark:bg-zinc-800',
        variant === 'success' && 'bg-green-100 dark:bg-green-900',
        variant === 'warning' && 'bg-amber-100 dark:bg-amber-900',
        variant === 'error' && 'bg-red-100 dark:bg-red-900',
      )}
    >
      <Text
        className={cn(
          'text-xs font-medium',
          variant === 'default' && ' ',
           ===  && ' ',
           ===  && ' ',
           ===  && ' ',
        )}
      >
        {label}
      
    
  );
}

// lib/utils.ts — cn helper
import { clsx, type ClassValue } from 'clsx';
import { twMerge } from 'tailwind-merge';

export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));
}

Responsive Platform Classes

import { View, Text } from 'react-native';

// NativeWind v4 supports platform modifiers
function PlatformAdaptive() {
  return (
    <View className="ios:pt-12 android:pt-8 web:pt-4 px-4 bg-white dark:bg-black">
      <Text className="ios:text-lg android:text-base font-semibold">
        Platform-specific styles
      </Text>
    </View>
  );
}

FlatList with NativeWind

import { FlatList, View, Text } from 'react-native';

interface Item { id: string; title: string; subtitle: string; }

function ItemRow({ item }: { item: Item }) {
  return (
    <View className="flex-row items-center px-4 py-3 border-b border-zinc-100 dark:border-zinc-800">
      <View className="w-10 h-10 rounded-full bg-indigo-100 dark:bg-indigo-900 items-center justify-center mr-3">
        <Text className="text-indigo-600 dark:text-indigo-300 font-bold text-base">
          {item.title[0]}
        </Text>
      </View>
      <View className="flex-1">
        <Text className="text-zinc-900 dark:text-white font-medium">{item.title}</Text>
        <Text className="text-zinc-500 dark:text-zinc-400 text-sm">{item.subtitle}</Text>
      </View>
    </>
  );
}

 () {
   (
    
  );
}

Custom CSS Variables (Theming)

/* global.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

@layer base {
  :root {
    --color-primary: 99 102 241;      /* indigo-500 */
    --color-background: 255 255 255;
    --color-foreground: 24 24 27;
  }
  .dark {
    --color-primary: 129 140 248;     /* indigo-400 */
    --color-background: 9 9 11;
    --color-foreground: 244 244 245;
  }
}

// tailwind.config.js
theme: {
  extend: {
    colors: {
      primary: 'rgb(var(--color-primary) / <alpha-value>)',
      background: 'rgb(var(--color-background) / <alpha-value>)',
      foreground: 'rgb(var(--color-foreground) / <alpha-value>)',
    },
  },
}

Common Pitfalls

• Dynamic class strings don't work: never concatenate class strings like "bg-" + color — Tailwind's static analyzer won't find them; use cn() with full class names or a cva variant map
• Metro cache must be cleared after config changes: npx expo start --clear after modifying tailwind.config.js or metro.config.js
• Not all Tailwind utilities translate to native: web-only utilities like grid, display: inline, and CSS Grid don't work on native — use flexbox equivalents
• className prop only works on core RN primitives: third-party components don't accept className unless they spread props — wrap them in a View with NativeWind or use cssInterop
• v4 vs v3 APIs differ significantly: v3 used styled() HOC from nativewind; v4 uses native className prop — don't mix tutorials from different versions
