CodePush: The Game-Changer for Over-the-Air Mobile App Updates

Introduction: Understanding CodePush and Its Impact on Mobile App Updates

CodePush has transformed the way mobile developers deliver updates by allowing over-the-air (OTA) deployments. You can fix bugs and ship improvements without waiting for app store approval. But with AppCenter shutting down in March 2025, finding a reliable alternative is more important than ever. In this article, we’ll break down how over-the-air updates work, what types of updates it supports, and how Appcircle offers a next-generation solution for seamless OTA delivery.

What is CodePush and How Does It Work?

CodePush is a cloud-based service offered by Microsoft’s App Center, allowing React Native developers to deliver over-the-air (OTA) real-time updates to their mobile applications. The core functionality of OTA updates is to inject updates without modifying the app’s native code. It acts as a central repository where developers can publish updates that do not require native code changes.

How does it enable over-the-air (OTA) updates?

To use the service, mobile developers are expected to integrate an SDK into their apps.
They also need to add deployment keys generated for this purpose into their apps.
The mobile application then communicates with the CodePush SDK and checks for updates continuously.
When an update is available, this update is applied to the mobile app dynamically.
The end-users experience the updated version of the app instantly without the need for reinstallation or updating the app.

What CodePush Can and Can’t Update?

Here is a summary of what you can and cannot update using CodePush:

Update Types	What CodePush CAN Update	What CodePush CANNOT Update
JavaScript	Logic changes, bug fixes, feature improvements	Native module changes, new dependencies
UI & Styling	Styles, UI tweaks, layout updates	New native UI components
Assets	Images, fonts, JSON files, localization	Native assets (e.g., vector drawables)
Permissions & Config	–	App permissions, Gradle/Xcode settings
React Native Framework	–	Major React Native upgrades

Is CodePush Allowed by Apple and Google?

Avoiding App Store Policy Violations

OTA updates are allowed by Apple and Google, but developers must ensure they do not violate any store policies. The key rule of thumb is that over-the-air (OTA) updates must NOT:

Change the app’s primary functionality
Introduce significant modifications
Release content that violates content policies

Additionally, it is recommended not to make substantial UI/UX changes without submitting the app for a full review.

Best Practices to Stay Compliant

Use OTA updates only for minor bug fixes, UI tweaks, and non-native updates.
Keep your app descriptions accurate to reflect any changes.
Allow users choose when to install updates and give them the option to roll back if something goes wrong.
Balance real-time updates with compliance to maintain end-user trust.
Use staged rollouts by gradually releasing updates to a percentage of users rather than releasing to all users
Monitor for issues
Follow Apple and Google’s latest guidelines to stay up to date with policy changes.

By following these best practices, developers can use CodePush seamlessly and safely while staying compliant with Apple and Google policies and maintaining trust and transparency with the end-users.

CodePush Alternatives: What Happens When CodePush is Retired?

App Center will no longer be available after March 31, 2025. Microsoft will continue to offer support until then, but once that date hits, the services will be fully shut down.

It’s a good idea to start looking for alternatives now. Migrating early gives you time to test things out and avoid any last-minute surprises when App Center shuts down.
