Accessing Device APIs: Camera, Location & Push Notifications

Use Expo SDK modules to request permissions and access native device capabilities.

Expo SDK Modules

The Expo SDK provides JavaScript APIs for native device capabilities. Install individual packages and request permissions before accessing hardware.

# Install what you need:
npx expo install expo-camera expo-location expo-notifications

Requesting Permissions

Always request permission before accessing sensitive device features. Check the result before proceeding.

import * as Location from 'expo-location';

async function getLocation() {
  const { status } = await Location.requestForegroundPermissionsAsync();
  if (status !== 'granted') {
    Alert.alert('Permission denied');
    return;
  }
  const location = await Location.getCurrentPositionAsync({});
  console.log(location.coords);
}
