How to use Expo Updates for OTA updates?

Question

Accepted Answer

**Expo Updates** — OTA updates for Expo apps.

**Setup:**
```bash
expo install expo-updates
```

**Configuration (app.json):**
```json
{
  "expo": {
    "updates": {
      "url": "https://u.expo.dev/YOUR_PROJECT_ID"
    }
  }
}
```

**Check for updates:**
```tsx
import * as Updates from 'expo-updates';

async function checkUpdates() {
  try {
    const update = await Updates.checkForUpdateAsync();
    if (update.isAvailable) {
      await Updates.fetchUpdateAsync();
      await Updates.reloadAsync();
    }
  } catch (e) {
    console.error("Update error:", e);
  }
}
```

**Auto-update on foreground:**
```tsx
Updates.addListener((event) => {
  if (event.type === Updates.UpdateEventType.UPDATE_AVAILABLE) {
    Updates.fetchUpdateAsync().then(() => {
      Updates.reloadAsync();
    });
  }
});
```

**Limitations:**
- Cannot update native code.
- JavaScript bundle only.
