How to Give In-App Updates in React Native

In-app updates have become an essential feature for modern mobile applications, enabling developers to deliver critical updates and feature enhancements without requiring users to visit app stores. This capability significantly improves user retention and satisfaction by minimizing disruption.

For React Native developers, the sp-react-native-in-app-updates library provides a robust solution for implementing this functionality across both Android and iOS platforms. This comprehensive guide explores the technical implementation, platform-specific configurations, and best practices for integrating in-app updates using this library.

The Importance of Seamless Update Mechanisms

Traditional app update processes require users to manually visit app stores, download updates, and restart applications. Studies show that 30% of users abandon apps requiring frequent manual updates. In-app updates address this by allowing:

  1. Immediate critical bug fixes to resolve crashes or security vulnerabilities.
  2. Feature rollouts aligned with marketing campaigns or user engagement strategies.
  3. A/B testing capabilities for experimental features without full releases.

Platform-Specific Implementations

The sp-react-native-in-app-updates library abstracts platform-specific complexities:

☑️ Android: Uses Google play core’s native APIs for flexible (background download) and immediate (blocking) update modes.
☑️ iOS: Leverages app store deep linking via react-native-siren to redirect users to store updates.

Setting Up sp-react-native-in-app-updates

npm install sp-react-native-in-app-updates --save
# or
yarn add sp-react-native-in-app-updates

Android Configuration

No additional native setup is required beyond standard React Native android configurations.

iOS Configuration

Add the following to your Info.plist to enable app store deep linking:

<key>LSApplicationQueriesSchemes</key>
<array>
<string>itms-apps</string>
</array>

Implementing Update Checks and Flows

Now we will see the step-by-step implementation of in-app updates.

Step 1:

Imports that we require for the implementation of the in-app updates. With all these necessary imports, we will ensure that everything is in place before we begin.

import SpInAppUpdates, {
IAUUpdateKind,
StartUpdateOptions,
IAUInstallStatus,
} from "sp-react-native-in-app-updates";

Step 2:

Here in this next step, we will initialize the in-app-updates library for further work.

const inAppUpdates = new SpInAppUpdates(false); // false = not in debug mode

Step 3:

This is the main functionality that we need to take care of.

try {
// Check if an update is required
const result = await inAppUpdates.checkNeedsUpdate();


try {
if (result.shouldUpdate) {
let updateOptions: StartUpdateOptions = {};


if (isAndroid) {
updateOptions = {
updateType: IAUUpdateKind.IMMEDIATE,
};
} else if (isIos) {
updateOptions = {
forceUpgrade: true,
title: iosUpdateConstants.title,
message: iosUpdateConstants.message,
buttonUpgradeText: iosUpdateConstants.buttonUpgradeText,
buttonCancelText: iosUpdateConstants.buttonCancelText,
};
}


// Listen to download status
inAppUpdates.addStatusUpdateListener((downloadStatus) => {
if (downloadStatus.status === IAUInstallStatus.DOWNLOADED) {
// Install the update
inAppUpdates.installUpdate();
inAppUpdates.removeStatusUpdateListener((finalStatus) => {});
}
});


// Start the update process
await inAppUpdates.startUpdate(updateOptions);
} else {
}
} catch (errr) {}
} catch (error) {}

Implementing In-App Updates

The following code snippet checks whether an update is required and, if so, starts the update process accordingly for Android and iOS:

Breakdown of the Code

Checking for updates: The checkNeedsUpdate() method determines whether an update is available by checking with the app distribution service.

Handling update options:

  1. Android:
    1. Uses IMMEDIATE mode, which forces the update to be applied immediately.
    2. Ensures that users are updated without delay, making it ideal for critical security patches or major bug fixes.
  2. iOS:
    1. Displays a custom upgrade dialogue with a title, message, and action buttons.
    2. Gives users control over when to update, but strongly encourages them to do so.

Listening to download status:

  1. Tracks the progress of the update download.
  2. Automatically installs the update once the download is complete to minimize user effort.
  3. Ensures that listeners are removed after installation to avoid memory leaks.

Error handling:

  1. Captures errors in both the update check and installation process.
  2. Logs errors to facilitate debugging and troubleshooting potential issues.

Best Practices for Implementing In-App Updates

Use IMMEDIATE updates only for critical fixes:

  1. IMMEDIATE updates force users to update before continuing to use the app.
  2. Should be reserved for high-priority fixes that prevent major issues or security vulnerabilities.
  3. Consider using FLEXIBLE updates for non-critical updates, allowing users to continue using the app while downloading.

Test updates in different scenarios:

  1. Ensure a smooth experience across various network conditions and device types.
  2. Simulate poor network environments to check how the update process handles disruptions.
  3. Test both IMMEDIATE and FLEXIBLE updates to ensure reliability.

Ensure proper user messaging:

  1. Customize prompts for iOS users to clearly explain why the update is needed.
  2. Provide informative and engaging messaging to encourage users to update promptly.
  3. Avoid overly aggressive prompts that may frustrate users and lead to uninstalls.

Monitor and analyze update adoption:

  1. Track how many users complete the update process.
  2. Use analytics tools to measure the effectiveness of your update prompts.
  3. Adjust messaging and update strategies based on user feedback and engagement.

Conclusion

By implementing in-app updates, you enhance user experience by ensuring they have the latest version without manually visiting the app store. This method provides a seamless and efficient way to manage app updates, leading to better user retention and fewer outdated versions in circulation. Proper implementation of in-app updates ensures users receive timely improvements while maintaining control over their experience.
