OTA Updates with Expo EAS Update: Faster Iterations Without Store Releases
Learn how Expo's EAS Update lets you push JavaScript and asset changes over‑the‑air, cutting release cycles while keeping native builds stable.
Insight
Expo EAS Update decouples JavaScript code from the native binary, allowing you to ship bug fixes, UI tweaks, or feature flags instantly to users. The OTA flow works only for changes that stay within the JavaScript bundle and bundled assets; any native module or SDK version bump still requires a store submission. By configuring a lightweight update check on app launch, you gain near‑instant feedback loops without sacrificing the safety of a full native release.
Example
import * as Updates from 'expo-updates';
export default function App() {
React.useEffect(() => {
async function checkForUpdates() {
const { isAvailable } = await Updates.checkForUpdateAsync();
if (isAvailable) await Updates.fetchUpdateAsync();
await Updates.reloadAsync(); // apply immediately
}
checkForUpdates();
}, []);
return <MainNavigator />;
}
Takeaway
Use EAS Update for any change that stays in the JavaScript layer—visual tweaks, content updates, or feature flags. Reserve traditional App Store releases for native module upgrades or SDK version changes to keep your binary stable.
