#What Works

Most React Native libraries work seamlessly on Meta Horizon OS if they're self-contained and don't depend on restricted services.

#Core Expo Libraries

These Expo libraries work out of the box:

• expo-file-system - File system operations
• expo-asset - Asset management
• expo-sqlite - Local database
• expo-camera - Camera access
• expo-audio - Audio playback
• expo-av - Media playback
• expo-image - Image handling

#React Native Libraries

Most React Native libraries work without modification:

• State management: Redux, Zustand, Jotai, etc.
• Networking: Fetch API, axios, etc.
• Animations: react-native-reanimated, react-native-gesture-handler
• UI libraries: Most component libraries work (may need VR-specific styling)
• Navigation: React Navigation works with VR considerations

#Rule of Thumb

If a library is self-contained and doesn't depend on external services or restricted hardware, it should work on Meta Horizon OS.

#Examples

#State Management

import { useState } from 'react';
import { useQuery } from '@tanstack/react-query';

// Works perfectly
function MyComponent() {
  const { data } = useQuery({
    queryKey: ['data'],
    queryFn: fetchData,
  });
  // ...
}

#Animations

import Animated from 'react-native-reanimated';

// Works out of the box
<Animated.View
  entering={FadeIn}
  exiting={FadeOut}
>
  <Text>Animated content</Text>
</Animated.View>

#File System

import * as FileSystem from 'expo-file-system';

// Works without modification
const fileUri = FileSystem.documentDirectory + 'file.txt';
await FileSystem.writeAsStringAsync(fileUri, 'content');
